London Underground

Early years

The Metropolitan Railway opened in 1863 using GWR broad-gauge locomotives.^[20]

Sub-surface lines

The idea of an underground railway linking the City of London with the urban centre was proposed in the 1830s,^[21] and the Metropolitan Railway was granted permission to build such a line in 1854.^[22] To prepare construction, a short test tunnel was built in 1855 in Kibblesworth, a small town with geological properties similar to London. This test tunnel was used for two years in the development of the first underground train, and was later, in 1861, filled up.^[23] The world's first underground railway, it opened in January 1863 between Paddington and Farringdon using gas-lit wooden carriages hauled by steam locomotives.^[24] It was hailed as a success, carrying 38,000 passengers on the opening day, and borrowing trains from other railways to supplement the service.^[25] The Metropolitan District Railway (commonly known as the District Railway) opened in December 1868 from South Kensington to Westminster as part of a plan for an underground "inner circle" connecting London's main-line stations.^[26] The Metropolitan and District railways completed the Circle line in 1884,^[27] built using the cut and cover method.^[28] Both railways expanded, the District building five branches to the west reaching Ealing, Hounslow,^[29] Uxbridge,^[30] Richmond and Wimbledon^[29] and the Metropolitan eventually extended as far as Verney Junction in Buckinghamshire, more than 50 miles (80 km) from Baker Street and the centre of London.^[31]

Deep-level lines

For the first deep-level tube line, the City and South London Railway, two 10 feet 2 inches (3.10 m) diameter circular tunnels were dug between King William Street (close to today's Monument station) and Stockwell, under the roads to avoid the need for agreement with owners of property on the surface. This opened in 1890 with electric locomotives that hauled carriages with small opaque windows, nicknamed padded cells.^[32] The Waterloo and City Railway opened in 1898,^[33] followed by the Central London Railway in 1900, known as the "twopenny tube".^[34] These two ran electric trains in circular tunnels having diameters between 11 feet 8 inches (3.56 m) and 12 feet 2.5 inches (3.72 m),^[35] whereas the Great Northern and City Railway, which opened in 1904, was built to take main line trains from Finsbury Park to a Moorgate terminus in the City and had 16-foot (4.9 m) diameter tunnels.^[36]

While steam locomotives were in use on the Underground there were contrasting health reports. There were many instances of passengers collapsing whilst travelling, due to heat and pollution, leading for calls to clean the air through the installation of garden plants.^[37] The Metropolitan even encouraged beards for staff to act as an air filter.^[38] There were other reports claiming beneficial outcomes of using the Underground, including the designation of Great Portland Street as a "sanatorium for [sufferers of ...] asthma and bronchial complaints", tonsillitis could be cured with acid gas and the Twopenny Tube cured anorexia.^[37]

Electrification

With the advent of electric Tube services (the Waterloo and City Railway and the Great Northern and City Railway), the Volks Electric Railway, in Brighton, and competition from electric trams, the pioneering Underground companies needed modernising.^[39] In the early 20th century, the District and Metropolitan railways needed to electrify and a joint committee recommended an AC system, the two companies co-operating because of the shared ownership of the inner circle. The District, needing to raise the finance necessary, found an investor in the American Charles Yerkes who favoured a DC system similar to that in use on the City & South London and Central London railways. The Metropolitan Railway protested about the change of plan, but after arbitration by the Board of Trade, the DC system was adopted.^[40]

Underground Electric Railways Company era

Yerkes soon had control of the District Railway and established the Underground Electric Railways Company of London (UERL) in 1902 to finance and operate three tube lines, the Baker Street and Waterloo Railway (Bakerloo), the Charing Cross, Euston and Hampstead Railway (Hampstead) and the Great Northern, Piccadilly and Brompton Railway, (Piccadilly), which all opened between 1906 and 1907.^[41][42] When the "Bakerloo" was so named in July 1906, The Railway Magazine called it an undignified "gutter title".^[42] By 1907 the District and Metropolitan Railways had electrified the underground sections of their lines.^[43]

In January 1913, the UERL acquired the Central London Railway and the City & South London Railway, as well as many of London's bus and tram operators.^[44] Only the Metropolitan Railway, along with its subsidiaries the Great Northern & City Railway and the East London Railway, and the Waterloo & City Railway, by then owned by the main line London and South Western Railway, remained outside the Underground Group's control.^[45]

A joint marketing agreement between most of the companies in the early years of the 20th century included maps, joint publicity, through ticketing and UNDERGROUND signs, incorporating the first bullseye symbol,^[37] outside stations in Central London.^[46] At the time, the term Underground was selected from three other proposed names; 'Tube' and 'Electric' were both officially rejected.^[37] Ironically, the term Tube was later adopted alongside the Underground. The Bakerloo line was extended north to Queen's Park to join a new electric line from Euston to Watford, but the First World War delayed construction and trains reached Watford Junction in 1917. During air raids in 1915 people used the tube stations as shelters.^[47] An extension of the Central line west to Ealing was also delayed by the war and was completed in 1920.^[48] After the war, government-backed financial guarantees were used to expand the network and the tunnels of the City and South London and Hampstead railways were linked at Euston and Kennington;^[49] the combined service was not named the Northern line until later.^[50] The Metropolitan promoted housing estates near the railway with the "Metro-land" brand and nine housing estates were built near stations on the line. Electrification was extended north from Harrow to Rickmansworth, and branches opened from Rickmansworth to Watford in 1925 and from Wembley Park to Stanmore in 1932.^[51][52] The Piccadilly line was extended north to Cockfosters and took over District line branches to Harrow (later Uxbridge) and Hounslow.^[53]

London Passenger Transport Board era

In 1933, most of London's underground railways, tramway and bus services were merged to form the London Passenger Transport Board, which used the London Transport brand.^[54] The Waterloo & City Railway, which was by then in the ownership of the main line Southern Railway, remained with its existing owners.^[55] In the same year that the London Passenger Transport Board was formed, Harry Beck's diagrammatic tube map first appeared.^[56]

In the following years, the outlying lines of the former Metropolitan Railway closed, the Brill Tramway in 1935, and the line from Quainton Road to Verney Junction in 1936.^[57] The 1935–40 New Works Programme included the extension of the Central and Northern lines and the Bakerloo line to take over the Metropolitan's Stanmore branch.^[58] The Second World War suspended these plans after the Bakerloo line had reached Stanmore and the Northern line High Barnet and Mill Hill East in 1941.^[59] Following bombing in 1940, passenger services over the West London line were suspended, leaving Olympia exhibition centre without a railway service until a District line shuttle from Earl's Court began after the war.^[60] After work restarted on the Central line extensions in east and west London, these were completed in 1949.^[61]

During the war many tube stations were used as air-raid shelters.^[62] They were not always a guarantee of safety however; on 11 January 1941 during the London Blitz, a bomb penetrated the booking hall of Bank Station, the blast from which killed 111 people, many of whom were sleeping in passage ways and on platforms.^[63] On 3 March 1943, a test of the air-raid warning sirens, together with the firing of a new type of anti-aircraft rocket, resulted in a crush of people attempting to take shelter in Bethnal Green Underground station. A total of 173 people, including 62 children, died, making this both the worst civilian disaster in Britain during the Second World War, and the largest loss of life in a single incident on the London Underground network.^[64]

London Transport Executive and Board era

On 1 January 1948, under the provisions of the Transport Act 1947, the London Passenger Transport Board was nationalised and renamed the London Transport Executive, becoming a subsidiary transport organisation of the British Transport Commission, which was formed on the same day.^[65][66][67] Under the same act, the country's main line railways were also nationalised, and their reconstruction was given priority over the maintenance of the Underground and most of the unfinished plans of the pre-war New Works Programme were shelved or postponed.^[68]

The District line needed new trains and an unpainted aluminium train entered service in 1953, this becoming the standard for new trains.^[69] In the early 1960s, the Metropolitan line was electrified as far as Amersham, British Railways providing services for the former Metropolitan line stations between Amersham and Aylesbury.^[70] In 1962, the British Transport Commission was abolished, and the London Transport Executive was renamed the London Transport Board, reporting directly to the Minister of Transport.^[66][71] Also during the 1960s, the Victoria line was dug under central London and, unlike the earlier tunnels, did not follow the roads above. The line opened in 1968–71 with the trains being driven automatically and magnetically encoded tickets collected by automatic gates gave access to the platforms.^[72]

Greater London Council era

On 1 January 1970 responsibility for public transport within Greater London passed from central government to local government, in the form of the Greater London Council (GLC), and the London Transport Board was abolished. The London Transport brand continued to be used by the GLC.^[73]

On 28 February 1975, a southbound train on the Northern City Line failed to stop at its Moorgate terminus and crashed into the wall at the end of the tunnel, in the Moorgate tube crash. There were 43 deaths and 74 injuries, the greatest loss of life during peacetime on the London Underground.^[74] In 1976 the Northern City Line was taken over by British Rail and linked up with the main line railway at Finsbury Park, a transfer that had already been planned prior to the accident.^[75]

In 1979 another new tube, the Jubilee line, named in honour of Queen Elizabeth's Silver Jubilee, took over the Stanmore branch from the Bakerloo line, linking it to a newly constructed tube between Baker Street and Charing Cross stations.^[76] Under the control of the GLC, London Transport introduced a system of fare zones for buses and underground trains that cut the average fare in 1981. Fares increased following a legal challenge but the fare zones were retained, and in the mid-1980s the Travelcard and the Capitalcard were introduced.^[77]

London Regional Transport era

In 1984 control of London Buses and the London Underground passed back to central government with the creation of London Regional Transport (LRT), which reported directly to the Secretary of State for Transport, still retaining the London Transport brand.^[78] One person operation had been planned in 1968, but conflict with the trade unions delayed introduction until the 1980s.^[79]

On 18 November 1987, fire broke out in an escalator at King's Cross St Pancras tube station. The resulting fire cost the lives of 31 people and injured a further 100. London Underground was strongly criticised in the aftermath for its attitude to fires underground, and publication of the report into the fire led to the resignation of senior management of both London Underground and London Regional Transport.^[80] Following the fire, substantial improvements to safety on the Tube were implemented - including the banning of smoking, removal of wooden escalators, installation of CCTV and fire detectors, as well as comprehensive radio coverage for the emergency services.^[81]

In April 1994, the Waterloo & City Railway, by then owned by British Rail and known as the Waterloo & City line, was transferred to the London Underground.^[55] In 1999, the Jubilee Line Extension project extended the Jubilee line from Green Park station through the growing Docklands to Stratford station. This resulted in the closure of the short section of tunnel between Green Park and Charing Cross stations. The 11 new stations were designed to be "future-proof", with wide passageways, large quantities of escalators and lifts, and emergency exits. The stations were the first on the Underground to have platform edge doors, and were built to have step free access throughout.^[82] The stations have subsequently been praised as exemplary pieces of 20th century architecture.^[83]

Transport for London era

In 2000, Transport for London (TfL) was created as an integrated body responsible for London's transport system. Part of the Greater London Authority, the TfL Board is appointed by the Mayor of London, who also sets the structure and level of public transport fares in London. The day-to-day running of the corporation is left to the Commissioner of Transport for London.^[84]

TfL eventually replaced London Regional Transport, and discontinued the use of the London Transport brand in favour of its own brand. The transfer of responsibility was staged, with transfer of control of London Underground delayed until July 2003, when London Underground Limited became an indirect subsidiary of TfL.^[85][86]

In the early 2000s, London Underground was reorganised in a Public-Private Partnership (PPP) as part of a project to upgrade and modernise the system. Private infrastructure companies (infracos) would upgrade and maintain the railway, and London Underground would run the train service. One infraco – Metronet – went into administration in 2007, and TfL took over the other – Tube Lines – in 2010.^[87] Despite this, substantial investment to upgrade and modernise the Tube has taken place - with new trains (such as London Underground S7 and S8 Stock), new signalling, upgraded stations (such as King's Cross St Pancras) and improved accessibility (such as at Green Park). Small changes to the Tube network occurred in the 2000s, with extensions to Heathrow Terminal 5, new station at Wood Lane and the Circle line changed from serving a closed loop around the centre of London to a spiral also serving Hammersmith in 2009.^[88]

In July 2005, four coordinated terrorist attacks took place, three of them occurring on the Tube network. It was the UK's deadliest terrorist incident since 1988.^[89]

Electronic ticketing in the form of the contactless Oyster card was first introduced in 2003,^[90] with payment using contactless banks cards introduced in September 2014.^[91] In 2019^[update], over 12 million Oyster cards and 35 million contactless cards were used, generating around £5bn in ticketing revenue.^[92]

During the London 2012 Olympic and Paralympic Games, the Underground saw record ridership levels, with over 4.3 million people using the Tube on some days.^[93] This record was subsequently beaten in later years, with 4.82 million riders in December 2015.^[94] In 2013, the Underground celebrated its 150th anniversary, with celebratory events such as steam trains and installation of a unique Labyrinth artwork at each station.^[95]

Under TfL, London's public transport network became more unified, with existing suburban rail lines across London upgraded and rebranded as London Overground from 2007, with the former East London line became part of the Overground network in 2010.^[96][97] Many Overground stations interchange with Underground ones, and Overground lines were added onto the Tube map.

In the 2010s, the £18.8bn Crossrail project built a new east–west railway tunnel under central London.^[98][99] The project involved rebuilding and expanding several central Underground stations including Tottenham Court Road and Whitechapel.^[98][100] By increasing rail capacity, the line aims to reduce overcrowding on the Tube and cut cross-London journey times.^[100] The railway opened as the Elizabeth line in May 2022.^[98] Although not part of the Underground, the line connects with several Underground stations.

In 2020, passenger numbers fell significantly during the COVID-19 pandemic and 40 stations were temporarily closed.^[101] The Northern Line Extension opened in September 2021, extending the Northern line from Kennington to Battersea Power Station via Nine Elms. The extension was privately funded, with contributions from developments across the Battersea Power Station, Vauxhall and Nine Elms areas.^[102][103]

History of the London Underground

History of the London Underground

The history of the London Underground began in the 19th century with the construction of the Metropolitan Railway, the world's first underground railway. The Metropolitan Railway, which opened in 1863 using gas-lit wooden carriages hauled by steam locomotives, worked with the District Railway to complete London's Circle line in 1884. Both railways expanded, the Metropolitan eventually extending as far as Verney Junction in Buckinghamshire, more than 50 miles (80 km) from Baker Street and the centre of London. The first deep-level tube line, the City and South London Railway, opened in 1890 with electric trains. This was followed by the Waterloo & City Railway in 1898, the Central London Railway in 1900, and the Great Northern and City Railway in 1904. The Underground Electric Railways Company of London (UERL) was established in 1902 to fund the electrification of the District Railway and to complete and operate three tube lines, the Baker Street and Waterloo Railway, the Charing Cross, Euston and Hampstead Railway and the Great Northern, Piccadilly and Brompton Railway, which opened in 1906–07. By 1907 the District and Metropolitan Railways had electrified the underground sections of their lines.

City of London

City of London

The City of London is a city, ceremonial county and local government district that contains the historic centre and constitutes, alongside Canary Wharf, the primary central business district (CBD) of London. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages, but the modern area named London has since grown far beyond the City of London boundary. The City is now only a small part of the metropolis of Greater London, though it remains a notable part of central London. Administratively, the City of London is not one of the London boroughs, a status reserved for the other 32 districts. It is also a separate ceremonial county, being an enclave surrounded by Greater London, and is the smallest ceremonial county in the United Kingdom.

Metropolitan Railway

Metropolitan Railway

The Metropolitan Railway was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the capital's financial heart in the City to what were to become the Middlesex suburbs. Its first line connected the main-line railway termini at Paddington, Euston, and King's Cross to the City. The first section was built beneath the New Road using cut-and-cover between Paddington and King's Cross and in tunnel and cuttings beside Farringdon Road from King's Cross to near Smithfield, near the City. It opened to the public on 10 January 1863 with gas-lit wooden carriages hauled by steam locomotives, the world's first passenger-carrying designated underground railway.

Kibblesworth

Kibblesworth

Kibblesworth is a village 2 miles (3.2 km) west of Birtley, Tyne and Wear, England. Kibblesworth was a mainly rural community until the development of the pit and brickworks and the resulting increase in population. Following the closure of the pit in 1974, few of the residents now work in the village. Historically in County Durham, it was transferred into the newly created county of Tyne and Wear in 1974.

Farringdon, London

Farringdon, London

Farringdon is a small district in Central London, the southern part of the London Borough of Islington. The term is used to describe the area around Farringdon station. Historically the district corresponded to southern Clerkenwell and the small parish of St Sepulchre Middlesex.

District Railway

District Railway

The Metropolitan District Railway, also known as the District Railway, was a passenger railway that served London from 1868 to 1933. Established in 1864 to complete an "inner circle" of lines connecting railway termini in London, the first part of the line opened using gas-lit wooden carriages hauled by steam locomotives. The Metropolitan Railway operated all services until the District Railway introduced its own trains in 1871. The railway was soon extended westwards through Earl's Court to Fulham, Richmond, Ealing and Hounslow. After completing the inner circle and reaching Whitechapel in 1884, it was extended to Upminster in Essex in 1902.

Circle line (London Underground)

Circle line (London Underground)

The Circle line is a spiral-shaped London Underground line, running from Hammersmith in the west to Edgware Road and then looping around central London back to Edgware Road. The railway is below ground in the central section and on the loop east of Paddington. Unlike London's deep-level lines, the Circle line tunnels are just below the surface and are of similar size to those on British main lines. Printed in yellow on the Tube map, the 17-mile (27 km) line serves 36 stations, including most of London's main line termini. Almost all of the route, and all the stations, are shared with one or more of the three other sub-surface lines, namely the District, Hammersmith & City and Metropolitan lines. On the Circle and Hammersmith & City lines combined, over 114 million passenger journeys were recorded in 2011/12.

Ealing

Ealing

Ealing is a district in West London, England, 7.5 miles (12.1 km) west of Charing Cross in the London Borough of Ealing. Ealing is the administrative centre of the borough and is identified as a major metropolitan centre in the London Plan.

Hounslow

Hounslow

Hounslow is a large suburban district of West London, 10+3⁄4 miles west-southwest of Charing Cross. It is the administrative centre of the London Borough of Hounslow, and is identified in the London Plan as one of the 12 metropolitan centres in Greater London.

Buckinghamshire

Buckinghamshire

Buckinghamshire, abbreviated Bucks, is a ceremonial county in South East England that borders Greater London to the south-east, Berkshire to the south, Oxfordshire to the west, Northamptonshire to the north, Bedfordshire to the north-east and Hertfordshire to the east.

Baker Street tube station

Baker Street tube station

Baker Street is a London Underground station at the junction of Baker Street and the Marylebone Road in the City of Westminster. It is one of the original stations of the Metropolitan Railway (MR), the world's first underground railway, opened on 10 January 1863.

City and South London Railway

City and South London Railway

The City and South London Railway (C&SLR) was the first successful deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotives—an experimental technology at the time—was chosen instead.

Railway

As of 2021, the Underground serves 272 stations.^[104][105] Sixteen Underground stations are outside London region, eight on the Metropolitan line and eight on the Central line. Of these, five (Amersham, Chalfont & Latimer, Chesham, and Chorleywood on the Metropolitan line, and Epping on the Central line), are beyond the M25 London Orbital motorway. Of the 32 London boroughs, six (Bexley, Bromley, Croydon, Kingston, Lewisham and Sutton) are not served by the Underground network, while Hackney has Old Street (on the Northern line Bank branch) and Manor House (on the Piccadilly line) only just inside its boundaries. Lewisham used to be served by the East London line (stations at New Cross and New Cross Gate). The line and the stations were transferred to the London Overground network in 2010.^[106]

A geographic London Underground map showing the extent of the current network (Amersham and Chesham stations, top left, are beyond the extent of the map.)

London Underground's eleven lines total 402 kilometres (250 mi) in length,^[1] making it the seventh longest metro system in the world. These are made up of the sub-surface network and the deep-tube lines.^[1] The Circle, District, Hammersmith & City, and Metropolitan lines form the sub-surface network, with railway tunnels just below the surface and of a similar size to those on British main lines, converging on a circular bi-directional loop around zone 1. The Hammersmith & City and Circle lines share stations and most of their track with each other, as well as with the Metropolitan and District lines. The Bakerloo, Central, Jubilee, Northern, Piccadilly, Victoria and Waterloo & City lines are deep-level tubes, with smaller trains that run in two circular tunnels (tubes) with a diameter about 11 feet 8 inches (3.56 m). These lines have the exclusive use of a pair of tracks, except for the Uxbridge branch of the Piccadilly line, which shares track with the District line between Acton Town and Hanger Lane Junction and with the Metropolitan line between Rayners Lane and Uxbridge; and the Bakerloo line, which shares track with London Overground's Watford DC Line for its aboveground section north of Queen's Park.^[107]

Fifty-five per cent of the system runs on the surface. There are 20 miles (32 km) of cut-and-cover tunnel and 93 miles (150 km) of tube tunnel.^[1] Many of the central London underground stations on deep-level tube routes are higher than the running lines to assist deceleration when arriving and acceleration when departing.^[108] Trains generally run on the left-hand track. In some places, the tunnels are above each other (for example, the Central line east of St Paul's station), or the running tunnels are on the right (for example on the Victoria line between Warren Street and King's Cross St. Pancras, to allow cross-platform interchange with the Northern line at Euston).^[107][109]

The lines are electrified with a four-rail DC system: a conductor rail between the rails is energised at −210 V and a rail outside the running rails at +420 V, giving a potential difference of 630 V. On the sections of line shared with mainline trains, such as the District line from East Putney to Wimbledon and Gunnersbury to Richmond, and the Bakerloo line north of Queen's Park, the centre rail is bonded to the running rails.^[110]

The average speed on the Underground is 20.5 mph (33.0 km/h).^[11] Outside the tunnels of central London, many lines' trains tend to travel at over 40 mph (64 km/h) in the suburban and countryside areas. The Metropolitan line can reach speeds of 62 mph (100 km/h).^[111]

Lines

The London Underground was used by 296.1 million passengers in 2020–21.^[3]

Services using former and current main lines

A map of the entire system with accurate positions of stations but simplified presentation of lines

The Underground uses several railways and alignments that were built by main-line railway companies.

Bakerloo line

Between Queen's Park and Harrow & Wealdstone this runs over the Watford DC Line also used by London Overground, alongside the London & North Western Railway (LNWR) main line that opened in 1837. The route was laid out by the LNWR in 1912–15 and is part of the Network Rail system.

Central line

The railway from just south of Leyton to just south of Loughton was built by Eastern Counties Railway in 1856 on the same alignment in use today.^[119] The Underground also uses the line built in 1865 by the Great Eastern Railway (GER) between Loughton to Ongar via Epping. The connection to the main line south of Leyton was closed in 1970 and removed in 1972. The line from Epping to Ongar was closed in 1994; most of the line is in use today by the heritage Epping Ongar Railway.^[119] The line between Newbury Park and Woodford junction (west of Roding Valley) via Hainault was built by the GER in 1903, the connections to the main line south of Newbury Park closing in 1947 (in the Ilford direction) and 1956 (in the Seven Kings direction).^[119]

Central line

The line from just north of White City to Ealing Broadway was built in 1917 by the Great Western Railway (GWR) and passenger service introduced by the Underground in 1920. North Acton to West Ruislip was built by GWR on behalf of the Underground in 1947–8 alongside the pre-existing tracks from Old Oak Common junction towards High Wycombe and beyond, which date from 1904.^[119] As of May 2013^[update], the original Old Oak Common junction to South Ruislip route has one main-line train a day to and from Paddington.^[120]

District line

• South of Kensington (Olympia) short sections of the 1862 West London Railway (WLR) and its 1863 West London Extension Railway (WLER) were used when District extended from Earl's Court in 1872. The District had its own bay platform at Olympia built in 1958 along with track on the bed of the 1862–3 WLR/WLER northbound. The southbound WLR/WLER became the new northbound main line at that time, and a new southbound main-line track was built through the site of former goods yard. The 1872 junction closed in 1958, and a further connection to the WLR just south of Olympia closed in 1992. The branch is now segregated.^[119]
• The line between Campbell Road junction (now closed), near Bromley-by-Bow, and Barking was built by the London, Tilbury & Southend Railway (LTSR) in 1858. The slow tracks were built 1903–05, when District services were extended from Bow Road (though there were no District services east of East Ham from 1905 to 1932). The slow tracks were shared with LTSR stopping and goods trains until segregated by 1962, when main-line trains stopped serving intermediate stations.^[119]
• The railway from Barking to Upminster was built by LTSR in 1885 and the District extended over the route in 1902. District withdrew between 1905 and 1932, when the route was quadrupled. Main-line trains ceased serving intermediate stations in 1962, and the District line today only uses the 1932 slow tracks.^[119]
• The westbound track between east of Ravenscourt Park and Turnham Green and Turnham Green to Richmond (also used by London Overground) follows the alignment of a railway built by the London & South Western Railway (LSWR) in 1869. The eastbound track between Turnham Green and east of Ravenscourt Park follows the alignment built in 1911; this was closed 1916 but was re-used when the Piccadilly line was extended in 1932.^[119] The section between Turnham Green and Richmond still belongs to Network Rail now.^[121]
• The line between East Putney and Wimbledon was built by the LSWR in 1889. The last scheduled main-line service ran in 1941^[119] but it still sees a few through Waterloo passenger services at the start and end of the daily timetable.^[122] The route is also used for scheduled ECS movements to/from Wimbledon Park depot and for Waterloo services diverted during disruptions and track closures elsewhere. This section is now owned by London Underground but the signalling is still operated by Network Rail.^[121]

Hammersmith & City

Between Paddington and Westbourne Park Underground station, the line runs alongside the main line. The Great Western main line opened in 1838, serving a temporary terminus the other side of Bishop's Road. When the current Paddington station opened in 1854, the line passed to the south of the old station.^[119] On opening in 1864, the Hammersmith & City Railway (then part of the Metropolitan Railway) ran via the main line to a junction at Westbourne Park, until 1867 when two tracks opened to the south of the main line, with a crossing near Westbourne Bridge, Paddington. The current two tracks to the north of the main line and the subway east of Westbourne Park opened in 1878.^[123] The Hammersmith & City route is now completely segregated from the main line.

Jubilee line

The rail route between Canning Town and Stratford was built by the GER in 1846, with passenger services starting in 1847. The original alignment was quadrupled "in stages between 1860 and 1892" for freight services before the extra (western) tracks were lifted as traffic declined during the 20th century, and were re-laid for Jubilee line services that started in 1999. The current Docklands Light Railway (ex-North London line) uses the original eastern alignment and the Jubilee uses the western alignment.^[119]

Northern line

The line from East Finchley to Mill Hill East was opened in 1867, and from Finchley Central to High Barnet in 1872, both by the Great Northern Railway.^[119]

Piccadilly line

The westbound track between east of Ravenscourt Park and Turnham Green was built by LSWR in 1869, and originally used for eastbound main-line and District services. The eastbound track was built in 1911; it closed in 1916 but was re-used when the Piccadilly line was extended in 1932.^[119]

Main line services using LU tracks

Chiltern Railways shares track with the Metropolitan Line between Harrow-on-the-Hill and Amersham. Three South Western Railway passenger trains a day use District Line tracks between Wimbledon and East Putney.^[124]

Trains

London Underground trains come in two sizes, larger sub-surface trains and smaller deep-tube trains.^[125] Since the early 1960s all passenger trains have been electric multiple units with sliding doors^[126] and a train last ran with a guard in 2000.^[127] All lines use fixed-length trains with between six and eight cars, except for the Waterloo & City line that uses four cars.^[128] New trains are designed for maximum number of standing passengers and for speed of access to the cars and have regenerative braking and public address systems.^[129] Since 1999 all new stock has had to comply with accessibility regulations that require such things as access and room for wheelchairs, and the size and location of door controls. All underground trains are required to comply with The Rail Vehicle Accessibility (Non Interoperable Rail System) Regulations 2010 (RVAR 2010) by 2020.^[130]

Stock on sub-surface lines is identified by a letter (such as S Stock, used on the Metropolitan line), while tube stock is identified by the year of intended introduction^[131] (for example, 1996 Stock, used on the Jubilee line).

Depots

The Underground is served by the following depots:

• Bakerloo: Stonebridge Park, Queen's Park, London Road
• Central: Hainault, Ruislip, White City
• Circle: Hammersmith
• District: Ealing Common, Lillie Bridge Depot, Upminster
• Hammersmith & City: Hammersmith
• Jubilee: Neasden, Stratford Market
• Metropolitan: Neasden
• Northern: Edgware, Golders Green, Highgate, Morden
• Piccadilly: Cockfosters, Northfields, South Harrow
• Victoria: Northumberland Park
• Waterloo & City: Waterloo
• London Underground: Acton Works

Disused and abandoned stations

In the years since the first parts of the London Underground opened, many stations and routes have been closed. Some stations were closed because of low passenger numbers rendering them uneconomical; some became redundant after lines were re-routed or replacements were constructed; and others are no longer served by the Underground but remain open to National Rail main line services. In some cases, such as Aldwych and Ongar, the buildings remain and are used for other purposes. In others, such as British Museum, all evidence of the station has been lost through demolition.

London Transport Museum runs guided tours of several disused stations including Down Street and Aldwych through its "Hidden London" programme. The tours look at the history of the network and feature historical details drawn from the museum's own archives and collections.^[132]

Proposed line extensions

Proposed route, safeguarded by TfL in 2021

Bakerloo line extension to Lewisham

A southern extension of the Bakerloo line from Elephant & Castle has been proposed multiple times since the line opened. In the 2010s, consultation events and preliminary design work took place on an extension. A route from Elephant & Castle to Lewisham via the Old Kent Road and New Cross Gate was chosen by Transport for London in 2019.^[133] The line could be extended further on the Hayes National Rail line in future. Estimated to cost between £4.7bn to £7.9bn (in 2017 prices), the extension would take around 7 years to construct.^[134] Due to financial impacts of the COVID-19 pandemic, work to implement the extension is currently on hold.^[135]

Other proposed extensions and lines

Several other extensions have been proposed in recent years, including a further extension of the Northern line to Clapham Junction.^[136] The long proposed Croxley Rail Link (an extension of the Metropolitan line) was cancelled in 2018 due to higher than expected costs and lack of funding.^[137][138] In 2019, the Canary Wharf Group suggested the construction of a new rail line between Euston and Canary Wharf, to improve connections to the future High Speed 2 railway.^[139]

Bakerloo line

The thirty-six 1972-stock trains on the Bakerloo line have already exceeded their original design life of 40 years. London Underground is therefore extending their operational life by making major repairs to many of the trains to maintain reliability. The Bakerloo line will receive new trains as part of the New Tube for London project. This will replace the existing fleet with new air-cooled articulated trains and a new signalling system to allow Automatic Train Operation. The line is predicted to run a maximum of 27 trains per hour, a 25% increase on the current 21 trains per hour during peak periods.^[140][141]

Central line

The Central line was the first line to be modernised in the 1990s, with 85 new 1992-stock trains and a new automatic signalling system installed to allow Automatic Train Operation. The line runs 34 trains per hour for half an hour in the morning peak but is unable to operate more frequently because of a lack of additional trains. The 85 existing 1992-stock trains are the most unreliable on the London Underground as they are equipped with the first generation of solid-state direct-current thyristor-control traction equipment. The trains often break down, have to be withdrawn from service at short notice and at times are not available when required, leading to gaps in service at peak times. Although relatively modern and well within their design life, the trains need work in the medium term to ensure the continued reliability of the traction control equipment and maintain fleet serviceability until renewal, which is expected between 2028 and 2032. Major work is to be undertaken on the fleet to ensure their continued reliability with brakes, traction control systems, doors, automatic control systems being repaired or replaced, among other components. The Central line will be part of the New Tube for London Project. This will replace the existing fleet with new air-cooled walkthrough trains and a new automatic signalling system. The line is predicted to run 36 trains per hour, a 25% increase compared to the present service of 34 trains for the busiest 30 minutes in the morning and evening peaks and 27–30 trains per hour during the rest of the peak.^{[140][142][143]}

Jubilee line

The signalling system on the Jubilee line has been replaced to increase capacity on the line by 20%—the line now runs 30 trains per hour at peak times, compared to the previous 24 trains per hour. As with the Victoria line, the service frequency is planned to increase to 36 trains per hour. To enable this, ventilation, power supply and control and signalling systems will be adapted and modified to allow the increase in frequency. London Underground also plans to add up to an additional 18 trains to the current fleet of 63 trains of 1996 stock.^[144][145]

Northern line

The signalling system on the Northern line has been replaced to increase capacity on the line by 20%, as the line now runs 24 trains per hour at peak times, compared to 20 previously. Capacity can be increased further if the operation of the Charing Cross and Bank branches is separated. To enable this up to 50 additional trains will be built in addition to the current 106 1995 stock. Five trains will be required for the Northern line extension and 45 to increase frequencies on the rest of the line. This, combined with segregation of trains at Camden Town junction, will allow 30–36 trains per hour compared to 24 trains per hour currently.^[145][146]

Piccadilly line

The eighty-six 1973 stock trains that operate on the Piccadilly line are some of the most reliable trains on the London Underground. The trains have exceeded their design life of around 40 years and are in need of replacement. The Piccadilly line will be part of the New Tube for London Project. This will replace the existing fleet with new air-cooled walk-through trains and a new signalling system to allow Automatic Train Operation. The line is predicted to run 30–36 trains per hour, up to a 50% increase compared to the 24–25 train per hour service provided today. The line will be the first to be upgraded as part of the New Tube for London Project, as passenger numbers have increased over recent years and are expected to increase further. This line is important in this project because it currently provides a less frequent service than other lines.^[140]

Victoria line

The signalling system on the Victoria line has been replaced to increase capacity on the line by around 25%; the line now runs up to 36 trains per hour compared to 27–28 previously. The trains have been replaced with 47 new higher-capacity 2009-stock trains. The peak frequency was increased to 36 trains per hour in 2016 after track works were completed to the layout of the points at Walthamstow Central crossover, which transfers northbound trains to the southbound line for their return journey. This resulted in a 40% increase in capacity between Seven Sisters and Walthamstow Central.^[147][148]

Waterloo & City line

The line was upgraded with five new 1992-stock trains in the early 1990s, at the same time as the Central line was upgraded. The line operates under traditional signalling and does not use Automatic Train Operation. The line will be part of the New Tube for London Project. This will replace the existing fleet with new air-cooled walk-through trains and a new signalling system to allow Automatic Train Operation. The line is predicted to run 30 trains per hour, an increase of up to 50% on the current 21 trains per hour. The line may also be one of the first to be upgraded, alongside the Piccadilly line, with new trains, systems and platform-edge doors to test the systems before the Central and Bakerloo lines are upgraded.^[140]

Sub-surface lines (District, Metropolitan, Hammersmith & City and Circle)

New S Stock trains have been introduced on the sub-surface (District, Metropolitan, Hammersmith & City and Circle) lines. These were all delivered by 2017. 191 trains have been introduced: 58 for the Metropolitan line and 133 for the Circle, District and Hammersmith & City lines. The track, electrical supply and signalling systems are also being upgraded in a programme to increase peak-hour capacity. The replacement of the signalling system and the introduction of Automatic Train Operation and Control is scheduled for 2019–22. A control room for the sub-surface network has been built in Hammersmith and an automatic train control (ATC) system is to replace ageing signalling equipment dating from between the mid-1920s and late 1980s, including the signal cabin at Edgware Road, the control room at Earl's Court, and the signalling centre at Baker Street. Bombardier won the contract in June 2011 but was released by agreement in December 2013, and London Underground has now issued another signalling contract, with Thales.^{[149][150][151]}

New trains for deep-level lines

In mid-2014 Transport for London issued a tender for up to 18 trains for the Jubilee line and up to 50 trains for the Northern line. These would be used to increase frequencies and cover the Battersea extension on the Northern line.^[152]

In early 2014 the Bakerloo, Central, Piccadilly and Waterloo & City line rolling-stock replacement project was renamed New Tube for London (NTfL) and moved from the feasibility stage to the design and specification stage. The study had showed that, with new generation trains and re-signalling:

• Piccadilly line capacity could be increased by 60% with 33 trains per hour (tph) at peak times by 2025.
• Central line capacity increased by 25% with 33 tph at peak times by 2030.
• Waterloo & City line capacity increased by 50% by 2032, after the track at Waterloo station is remodelled.
• Bakerloo line capacity could be increased by 25% with 27 tph at peak times by 2033.

The project is estimated to cost £16.42 billion (£9.86 billion at 2013 prices). A notice was published on 28 February 2014 in the Official Journal of the European Union asking for expressions of interest in building the trains.^[153][154] On 9 October 2014 TFL published a shortlist of those (Alstom, Siemens, Hitachi, CAF and Bombardier) who had expressed an interest in supplying 250 trains for between £1.0 billion and £2.5 billion, and on the same day opened an exhibition with a design by PriestmanGoode.^[155][156] The fully automated trains may be able to run without drivers,^[157] but the ASLEF and RMT trade unions that represent the drivers strongly oppose this, saying it would affect safety.^[158] The invitation to tender for the trains was issued in January 2016;^[159] the specifications for the Piccadilly line infrastructure are expected in 2016,^[153][154] and the first train is due to run on the Piccadilly line in 2023.^[160] Siemens Mobility's Inspiro design was selected in June 2018 in a £1.5 billion contract.^[161]

Ventilation and cooling

When the Bakerloo line opened in 1906, it was advertised with a maximum temperature of 60 °F (16 °C), but over time the tube tunnels have warmed up.^[162] In 1938 approval was given for a ventilation improvement programme, and a refrigeration unit was installed in a lift shaft at Tottenham Court Road.^[162] Temperatures of 117 °F (47 °C) were reported in the 2006 European heat wave.^[163] It was claimed in 2002 that, if animals were being transported, temperatures on the Tube would break European Commission animal welfare laws.^[164] A 2000 study reported that air quality was seventy-three times worse than at street level, with a passenger inhaling the same mass of particulates during a twenty-minute journey on the Northern line as when smoking a cigarette.^[165][166] The main purpose of the London Underground's ventilation fans is to extract hot air from the tunnels,^[162] and fans across the network are being refurbished, although complaints of noise from local residents preclude their use at full power at night.^[167]

In June 2006 a groundwater cooling system was installed at Victoria station.^[168] In 2012, air-cooling units were installed on platforms at Green Park station using cool deep groundwater and at Oxford Circus using chiller units at the top of an adjacent building.^[169] New air-conditioned trains have been introduced on the sub-surface lines, but was initially ruled out for the tube trains due to space being considered limited on tube trains for air-conditioning units and that these would heat the tunnels even more. The New Tube for London, which will replace the trains for the Bakerloo, Central, Waterloo and City and Piccadilly lines, is planned to have air conditioning for the new trains along with better energy conservation and regenerative braking.^{[129][170][171]}

In the original Tube design, trains passing through close fitting tunnels act as pistons to create air pressure gradients between stations. This pressure difference drives ventilation between platforms and the surface exits through the passenger foot network. This system depends on adequate cross-sectional area of the airspace above the passengers’ heads in the foot tunnels and escalators, where laminar airflow is proportional to the fourth power of the radius, the Hagen–Poiseuille equation. It also depends on an absence of turbulence in the tunnel headspace. In many stations the ventilation system is now ineffective because of alterations that reduce tunnel diameters and increase turbulence. An example is Green Park tube station, where false ceiling panels attached to metal frames have been installed that reduce the above-head airspace diameter by more than half in many parts. This has the effect of reducing laminar airflow by 94%.

Originally, air turbulence was kept to a minimum by keeping all signage flat to the tunnel walls. Now, the ventilation space above head height is crowded with ducting, conduits, cameras, speakers and equipment acting as a baffle plates with predictable reductions in flow.^[172] Often, electronic signs have their flat surface at right angles to the main air flow, causing choked flow. Temporary sign boards that stand at the top of escalators also maximise turbulence. The alterations to the ventilation system are important, not only to heat exchange, but also the quality of the air at platform level, particularly given its asbestos content.^[173]

Lifts and escalators

Escalators at Canary Wharf station

Originally access to the deep-tube platforms was by a lift.^[174] Each lift was staffed, and at some quiet stations in the 1920s the ticket office was moved into the lift, or it was arranged that the lift could be controlled from the ticket office.^[175] The first escalator on the London Underground was installed in 1911 between the District and Piccadilly platforms at Earl's Court and from the following year new deep-level stations were provided with escalators instead of lifts.^[176] The escalators had a diagonal shunt at the top landing.^[176][177] In 1921 a recorded voice instructed passengers to stand on the right and signs followed in the Second World War.^[178] Travellers were asked to stand on the right so that anyone wishing to overtake them would have a clear passage on the left side of the escalator.^[179] The first 'comb' type escalator was installed in 1924 at Clapham Common.^[176] In the 1920s and 1930s many lifts were replaced by escalators.^[180] After the fatal 1987 King's Cross fire, all wooden escalators were replaced with metal ones and the mechanisms are regularly degreased to lower the potential for fires.^[181] The only wooden escalator not to be replaced was at Greenford station, which remained until March 2014 when TfL replaced it with the first incline lift on the UK transport network in October 2015.^[182]

There are 426 escalators on the London Underground system and the longest, at 60 metres (200 ft), is at Angel. The shortest, at Stratford, gives a vertical rise of 4.1 metres (13 ft). There are 184 lifts,^[183] and numbers have increased in recent years because of investment in making tube stations accessible. Over 28 stations will have lifts installed over the next 10 years, bringing the total of step-free stations to over 100.^[184] Lift and escalators are abundant with advertising posters which can be used for artistic purposes due to the nature of their layout.^[185]

Wi-Fi and mobile phone reception

In mid-2012, London Underground, in partnership with Virgin Media, tried out Wi-Fi hot spots in many stations, but not in the tunnels, that allowed passengers free internet access. The free trial proved successful and was extended to the end of 2012,^[186] whereupon it switched to a service freely available to subscribers to Virgin Media and others, or as a paid-for service.^[187] It was not previously possible to use mobile phones on most parts of the Underground (excluding services running overground or occasionally sub-surface, depending on the phone and carrier) using native 2G, 3G or 4G networks, and a project to extend coverage before the 2012 Olympics was abandoned because of commercial and technical difficulties.^[188]

This partially changed in March 2020, when 4G signal was made available on parts of the Jubilee line, between Westminster and Canning Town, throughout the stations and tunnels.^[189] UK subscribers to the Three mobile network can use the^[190] InTouch^[191] app to route their voice calls and texts messages via the Virgin Media Wifi network at 138 London Transport stations.^[192] The EE network has also recently released a WiFi calling feature available on the iPhone.^[193]

Ticketing

The Oyster card, a contactless smart card used across the London transport system

The Underground received £2.669 billion in fares in 2016/17 and uses Transport for London's zonal fare system to calculate fares.^[194] There are nine zones with zone 1 being the central zone, which includes the loop of the Circle line with a few stations to the south of River Thames. The only London Underground stations in Zones 7 to 9 are on the Metropolitan line beyond Moor Park, outside London region. Some stations are in two zones, and the cheapest fare applies.^[195] Paper tickets, the contactless Oyster cards, contactless debit or credit cards^[196] and Apple Pay^[197] and Android Pay^[198] smartphones and watches can be used for travel.^[199] Single and return tickets are available in either format, but Travelcards (season tickets) for longer than a day are available only on Oyster cards.^{[200][201][202]}

TfL introduced the Oyster card in 2003; this is a pre-payment smartcard with an embedded contactless RFID chip.^[203] It can be loaded with Travelcards and used on the Underground, the Overground, buses, trams, the Docklands Light Railway, and National Rail services within London.^[204] Fares for single journeys are cheaper than paper tickets, and a daily cap limits the total cost in a day to the price of a Day Travelcard.^[205] The Oyster card must be 'touched in' at the start and end of a journey, otherwise it is regarded as 'incomplete' and the maximum fare is charged.^[206] In March 2012 the cost of this in the previous year to travellers was £66.5 million.^[207]

In 2014, TfL became the first public transport provider in the world to accept payment from contactless bank cards.^[16] The Underground first started accepting contactless debit and credit cards in September 2014.^[15] This was followed by the adoption of Apple Pay in 2015^[197] and Android Pay in 2016,^[198] allowing payment using a contactless-enabled phone or smartwatch. Over 500 million journeys have taken place using contactless, and TfL has become one of Europe's largest contactless merchants, with around 1 in 10 contactless transactions in the UK taking place on the TfL network.^[16] This technology, developed in-house by TfL,^[208] has been licensed to other major cities like New York City^[209] and Boston.^[210]

A concessionary fare scheme is operated by London Councils for residents who are disabled or meet certain age criteria.^[211] Residents born before 1951 were eligible after their 60th birthday, whereas those born in 1955 will need to wait until they are 66.^[212] Called a "Freedom Pass" it allows free travel on TfL-operated routes at all times and is valid on some National Rail services within London at weekends and after 09:30 on Monday to Fridays.^[213] Since 2010, the Freedom Pass has included an embedded holder's photograph; it lasts five years between renewals.^[214]

In addition to automatic and staffed faregates at stations, the Underground also operates on a proof-of-payment system. The system is patrolled by both uniformed and plain-clothes fare inspectors with hand-held Oyster-card readers. Passengers travelling without a valid ticket must pay a penalty fare of £80 (£40 if paid within 21 days) and can be prosecuted for fare evasion under the Regulation of Railways Act 1889 and Transport for London Byelaws.^[215][216]

Hours of operation

The tube closes overnight during the week, but since 2016, the Central, Jubilee, Northern, Piccadilly, and Victoria lines, as well as a short section of the London Overground have operated all night on Friday and Saturday nights. The first trains run from about 05:00 and the last trains until just after 01:00, with later starting times on Sunday mornings.^[217][218] The nightly closures are used for maintenance,^[217] but some lines stay open on New Year's Eve^[219] and run for longer hours during major public events such as the 2012 London Olympics.^[220] Some lines are occasionally closed for scheduled engineering work at weekends.^[221]

The Underground runs a limited service on Christmas Eve with some lines closing early, and does not operate on Christmas Day.^[219] Since 2010 a dispute between London Underground and trade unions over holiday pay has resulted in a limited service on Boxing Day.^[222]

Night Tube

Route map of Night Tube

On 19 August 2016, London Underground launched a 24-hour service on the Victoria and Central lines with plans in place to extend this to the Piccadilly, Northern and Jubilee lines starting on Friday morning and continuing right through until Sunday evening.^[223] The Night Tube proposal was originally scheduled to start on 12 September 2015, following completion of upgrades, but in August 2015 it was announced that the start date for the Night Tube had been pushed back because of ongoing talks about contract terms between trade unions and London Underground.^[224][225] On 23 May 2016 it was announced that the night service would launch on 19 August 2016 for the Central and Victoria lines. The service operates on the:

Central line

between Ealing Broadway and Hainault via Newbury Park or Loughton. No service on the West Ruislip Branch, between Woodford and Hainault via Grange Hill or between Loughton and Epping.

Northern line

between Morden and Edgware / High Barnet via Charing Cross. No service on Mill Hill East, Battersea or Bank branches.

Piccadilly line

between Cockfosters and Heathrow Terminals 1, 2, 3 and 5. No service to Terminal 4 or between Acton Town and Uxbridge.

Jubilee line

Full line – Stratford to Stanmore.

Victoria line

Full line – Walthamstow Central to Brixton.

The Jubilee, Piccadilly and Victoria lines, and the Central line between White City and Leytonstone, operate at 10-minute intervals. The Central line operates at 20-minute intervals between Leytonstone and Hainault, between Leytonstone and Loughton, and between White City and Ealing Broadway. The Northern line operates at roughly 8-minute intervals between Morden and Camden Town via Charing Cross, and at 15-minute intervals between Camden Town and Edgware and between Camden Town and High Barnet.^[226]

Night Tube services were suspended in March 2020, during the COVID-19 pandemic.^[227]

Accessibility

A wheelchair user on a Tube train

Accessibility for people with limited mobility was not considered when most of the system was built, and before 1993 fire regulations prohibited wheelchairs on the Underground.^[228] The stations on the Jubilee Line Extension, opened in 1999, were the first stations on the system designed with accessibility in mind, but retrofitting accessibility features to the older stations is a major investment that is planned to take over twenty years.^[229] A 2010 London Assembly report concluded that over 10% of people in London had reduced mobility^[230] and, with an ageing population, numbers will increase in the future.^[231]

The standard issue tube map indicates stations that are step-free from street to platforms. There can also be a step from platform to train as large as 12 inches (300 mm) and a gap between the train and curved platforms, and these distances are marked on the map. Access from platform to train at some stations can be assisted using a boarding ramp operated by staff, and a section has been raised on some platforms to reduce the step.^[232][233]

As of January 2022^[update], there are 90 stations with step-free access from platform to train,^{[184][234][235]} and there are plans to provide step-free access at another 11 stations by 2024.^[235] By 2016 a third of stations had platform humps that reduce the step from platform to train.^[236] New trains, such as those being introduced on the sub-surface network, have access and room for wheelchairs, improved audio and visual information systems and accessible door controls.^[236][130]

Delays and overcrowding

An overcrowded Northern line train. Overcrowding is a regular problem for Tube passengers, especially during peak hours.

During peak hours, stations can get so crowded that they need to be closed. Passengers may not get on the first train^[237] and the majority of passengers do not find a seat on their trains,^[238] some trains having more than four passengers every square metre.^[239] When asked, passengers report overcrowding as the aspect of the network that they are least satisfied with, and overcrowding has been linked to poor productivity and potential poor heart health.^[240] Capacity increases have been overtaken by increased demand, and peak overcrowding has increased by 16 percent since 2004–05.^[241]

Compared with 2003–04, the reliability of the network had increased in 2010–11, with lost customer hours reduced from 54 million to 40 million.^[242] Passengers are entitled to a refund if their journey is delayed by 15 minutes or more due to circumstances within the control of TfL,^[243] and in 2010, 330,000 passengers out of a potential 11 million Tube passengers claimed compensation for delays.^[244] Mobile phone apps and services have been developed to help passengers claim their refund more efficiently.^[245]

Safety

London Underground is authorised to operate trains by the Office of Rail Regulation. As at 19 March 2013^[update] there had been 310 days since the last major incident,^[246] when a passenger had died after falling on the track.^[247] As of 2015^[update] there have been nine consecutive years in which no employee fatalities have occurred.^[248] A special staff training facility was opened at West Ashfield tube station in TFL's Ashfield House, West Kensington in 2010 at a cost of £800,000. Meanwhile, Mayor of London Boris Johnson decided it should be demolished along with the Earls Court Exhibition Centre as part of Europe's biggest regeneration scheme.^[249]

In November 2011 it was reported that 80 people had died by suicide in the previous year on the London Underground, up from 46 in 2000.^[250] Most platforms at deep tube stations have pits, often referred to as 'suicide pits', beneath the track. These were constructed in 1926 to aid drainage of water from the platforms, but also halve the likelihood of a fatality when a passenger falls or jumps in front of a train.^{[251][252][253]}

Fast and semi-fast services

The Metropolitan line operates express services, known as "fast" or "semi-fast", which do not stop at certain stations, thus decreasing total travelling time and increasing capacity. Stopping services, which stop at every station on the route, may be described as "all-stations" services. Fast and semi-fast services operate only during peak hours; southbound only in the mornings, northbound only in the evenings.

The Tube Challenge

The Tube Challenge is the competition for the fastest time to travel to all London Underground stations, tracked by Guinness World Records since 1960. The goal is to visit all the stations on the system, but not necessarily using all the lines; participants may connect between stations on foot, or by using other forms of public transport.

As of 2021, the record for fastest completion was held by Steve Wilson (UK) and Andi James (Finland), who completed the challenge in 15 hours, 45 minutes and 38 seconds on 21 May 2015.^[254]

London fare zones

London fare zones

Rail service fares in Greater London and the surrounding area are calculated in accordance with the London fare zones system managed by Transport for London. Within London, all London Underground, National Rail, London Overground, TfL Rail and Docklands Light Railway stations are assigned to six fare zones. Fare zone 1 covers the central area and fare zones 2, 3, 4, 5 and 6 form concentric rings around it. Some National Rail stations and almost all Transport for London served stations outside Greater London in the home counties of Buckinghamshire, Essex, Hertfordshire and Surrey are either included in fare zones 4, 5 or 6 or in extended zones beyond these. Transport for London fare zones are also known simply as zones or travelcard zones, referring to their use in calculating prices for the travelcards or pay-as-you-go caps. Before flat fares were introduced in 2004, fare zones were used on the London Buses network. London fare zones are also used for calculating the cost of single and return paper tickets, Oyster card pay-as-you-go fares and season tickets.

Moor Park tube station

Moor Park tube station

Moor Park is a London Underground station in the Three Rivers district of Hertfordshire, serving those living on the Moor Park estate, and also on the neighbouring Eastbury and South Oxhey estates. The station is outside the Greater London boundary but is in both Zone 6 and Zone 7, between the Metropolitan line stations of Rickmansworth, Croxley and Northwood.

Greater London

Apple Pay

Apple Pay

Apple Pay is a mobile payment service by Apple Inc. that allows users to make payments in person, in iOS apps, and on the web. It is supported on iPhone, Apple Watch, iPad, and Mac. It digitizes and can replace a credit or debit card chip and PIN transaction at a contactless-capable point-of-sale terminal. It does not require Apple Pay-specific contactless payment terminals; it can work with any merchant that accepts contactless payments. It adds two-factor authentication via Touch ID, Face ID, PIN, or passcode. Devices wirelessly communicate with point of sale systems using near field communication (NFC), with an embedded secure element (eSE) to securely store payment data and perform cryptographic functions, and Apple's Touch ID and Face ID for biometric authentication.

Contactless payment

Contactless payment

Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication for making secure payments. The embedded integrated circuit chip and antenna enable consumers to wave their card, fob, or handheld device over a reader at the point of sale terminal. Contactless payments are made in close physical proximity, unlike other types of mobile payments which use broad-area cellular or WiFi networks and do not involve close physical proximity.

Debit card

Debit card

A debit card, also known as a check card or bank card is a payment card that can be used in place of cash to make purchases. The term plastic card includes the above and as an identity document. These are similar to a credit card, but unlike a credit card, the money for the purchase must be in the cardholder's bank account at the time of a purchase and is immediately transferred directly from that account to the merchant's account to pay for the purchase.

Credit card

Credit card

A credit card is a payment card issued to users (cardholders) to enable the cardholder to pay a merchant for goods and services based on the cardholder's accrued debt. The card issuer creates a revolving account and grants a line of credit to the cardholder, from which the cardholder can borrow money for payment to a merchant or as a cash advance. There are two credit card groups: consumer credit cards and business credit cards. Most cards are plastic, but some are metal cards, and a few gemstone-encrusted metal cards.

In 2021, the system had a ridership of 160,557,600, or about 678,000 per weekday as of the third quarter of 2022, of which the rapid transit lines averaged 246,700 and the light rail lines 82,600, making it the fourth-busiest rapid transit system and the third-busiest light rail system in the United States. As of the third quarter of 2022, average weekday ridership of the commuter rail system was 69,400, making it the sixth-busiest commuter rail system in the U.S.

Freedom Pass

Freedom Pass

Freedom Pass is a concessionary travel scheme, which began in 1973, to provide free travel to residents of Greater London, England, who are aged 66 and over or who have a disability. The scheme is funded by local authorities and coordinated by London Councils. Originally the pass was a paper ticket, but since 2004 it has been encoded on to a contactless smartcard compatible with Oyster card readers.

Map

The left side shows the 1933 Beck map and the right side the map in 2012.

Early maps of the Metropolitan and District railways were city maps with the lines superimposed,^[255] and the District published a pocket map in 1897.^[256] A Central London Railway route diagram appears on a 1904 postcard and 1905 poster,^[257] similar maps appearing in District Railway cars in 1908.^[258] In the same year, following a marketing agreement between the operators, a joint central area map that included all the lines was published.^[259][260] A new map was published in 1921 without any background details, but the central area was squashed, requiring smaller letters and arrows.^[261] Although Fred H. Stingemore enlarged the central area of the map, it was Harry Beck who took this further by distorting geography and simplifying the map so that the railways appeared as straight lines with equally spaced stations.^[262] He presented his original draft in 1931, and after initial rejection it was first printed in 1933. Today's tube map is an evolution of that original design, and the ideas are used by many metro systems around the world.^[263][264]

The current standard tube map shows the Docklands Light Railway, London Overground, Emirates Air Line, London Tramlink and the London Underground;^[265] a more detailed map covering a larger area, published by National Rail and Transport for London, includes suburban railway services.^[195] The tube map came second in a BBC and London Transport Museum poll asking for a favourite UK design icon of the 20th century^[266] and the underground's 150th anniversary was celebrated by a Google Doodle on the search engine.^[267][268]

Commissioned by Art on the Underground, the cover of the pocket map is designed by various British and international artists, one of the largest public art commissions in the UK.^[269]

Roundel

While the first use of a roundel in a London transport context was the trademark of the London General Omnibus Company registered in 1905, it was first used on the Underground in 1908 when the UERL placed a solid red circle behind station nameboards on platforms to highlight the name.^[270][271] The word "UNDERGROUND" was placed in a roundel instead of a station name on posters in 1912 by Charles Sharland and Alfred France, as well as on undated and possibly earlier posters from the same period.^[272] Frank Pick, impressed by the Paris Metro, thought the solid red disc cumbersome and took a version where the disc became a ring from a 1915 Sharland poster and gave it to Edward Johnston to develop, and registered the symbol as a trademark in 1917.^[273][39] The roundel was first printed on a map cover using the Johnston typeface in June 1919, and printed in colour the following October.^[274]

After the UERL was absorbed into the London Passenger Transport Board in 1933, it used forms of the roundel for buses, trams and coaches, as well as the Underground. The words "London Transport" were added inside the ring, above and below the bar. The Carr-Edwards report, published in 1938 as possibly the first attempt at a graphics standards manual, introduced stricter guidelines.^[275] Between 1948 and 1957 the word "Underground" in the bar was replaced by "London Transport".^[276] As of 2013^[update], forms of the roundel, with differing colours for the ring and bar, are used for other TfL services, such as London Buses, Tramlink, London Overground, London River Services and Docklands Light Railway.^[277] Crossrail will also be identified with a roundel.^[278] The 100th anniversary of the roundel was celebrated in 2008 by TfL commissioning 100 artists to produce works that celebrate the design.^[279][280]

In 2016, Tate Modern commissioned conceptual artist Michael Craig-Martin to "reimagine" the roundel, changing its colours for the first time since the sign was introduced. His design was displayed at Southwark Station in collaboration with Art on the Underground to mark the opening weekend of the new Tate Modern gallery situated near the station.^[281]

Architecture

Seventy of the 272 London Underground stations use buildings that are on the Statutory List of Buildings of Special Architectural or Historic Interest, and five have entrances in listed buildings.^[282] The Metropolitan Railway's original seven stations were inspired by Italianate designs, with the platforms lit by daylight from above and by gas lights in large glass globes.^[283] Early District Railway stations were similar and on both railways the further from central London the station the simpler the construction.^[284] The City & South London Railway opened with red-brick buildings, designed by Thomas Phillips Figgis, topped with a lead-covered dome that contained the lift mechanism and weather vane (still visible at many stations e.g. Clapham Common.^[37][285] The Central London Railway appointed Harry Bell Measures as architect, who designed its pinkish-brown steel-framed buildings with larger entrances.^[286]

Russell Square, one of the UERL stations designed by Leslie Green clad in ox-blood tiles

55 Broadway, above St James's Park station, was designed by Charles Holden in 1927 and is one of only two Grade I listed buildings on the Underground.

In the first decade of the 20th century Leslie Green established a house style for the tube stations built by the UERL, which were clad in ox-blood faience blocks.^[287] Green pioneered using building design to guide passengers with direction signs on tiled walls, with the stations given a unique identity with patterns on the platform walls.^[288][289] Many of these tile patterns survive, though a significant number of these are now replicas.^[290] Harry W. Ford was responsible for the design of at least 17 UERL and District Railway stations, including Barons Court and Embankment, and claimed to have first thought of enlarging the U and D in the UNDERGROUND wordmark.^[291] The Met's architect Charles Walter Clark had used a neo-classical design for rebuilding Baker Street and Paddington Praed Street stations before the First World War and, although the fashion had changed, continued with Farringdon in 1923. The buildings had metal lettering attached to pale walls.^[286] Clark would later design "Chiltern Court", the large, luxurious block of apartments at Baker Street, that opened in 1929.^[292] In the 1920s and 1930s, Charles Holden designed a series of modernist and art-deco stations some of which he described as his 'brick boxes with concrete lids'.^[293] Holden's design for the Underground's headquarters building at 55 Broadway included avant-garde sculptures by Jacob Epstein, Eric Gill and Henry Moore.^[294][295]

When the Central line was extended east, the stations were simplified Holden proto-Brutalist designs,^[296] and a cavernous concourse built at Gants Hill in honour of early Moscow Metro stations.^[297] Few new stations were built in the 50 years after 1948, but Misha Black was appointed design consultant for the 1960s Victoria line, contributing to the line's uniform look,^[298] with each station having an individual tile motif.^[299] Notable stations from this period include Moor Park, the stations of the Piccadilly line extension to Heathrow and Hillingdon.

In recent years, the stations of the 1990s Jubilee Line Extension were designed in a high-tech style by architects such as Norman Foster and Michael Hopkins.^[300] The project was critically acclaimed, with the Royal Fine Arts Commission describing the project as "an example of patronage at its best and most enlightened", and two stations shortlisted for the Stirling Prize.^[301] Stations were built to the latest standards, future proofed for growth, with innovations such as Platform screen doors.^[302] West Ham station was built as a homage to the red brick tube stations of the 1930s, using brick, concrete and glass.

Many platforms have unique interior designs to help passenger identification. The tiling at Baker Street incorporates repetitions of Sherlock Holmes's silhouette,^[303] at Tottenham Court Road semi-abstract mosaics by Eduardo Paolozzi feature musical instruments, tape machines and butterflies, ^[304] and at Charing Cross, David Gentleman designed the mural depicting the construction of the Eleanor Cross.^[37] Robyn Denny designed the murals on the Northern line platforms at Embankment.^[303]

Johnston typeface

The first posters used various type fonts, as was contemporary practice,^[305] and station signs used sans serif block capitals.^[306] The Johnston typeface was developed in upper and lower case in 1916, and a complete set of blocks, marked Johnston Sans, was made by the printers the following year.^[307] A bold version of the capitals was developed by Johnston in 1929.^[308] The Met changed to a serif letterform for its signs in the 1920s, used on the stations rebuilt by Clark.^[309] Johnston was adopted systemwide after the formation of the LPTB in 1933 and the LT wordmark was applied to locomotives and carriages.^[310] Johnston was redesigned, becoming New Johnston, for photo-typesetting in the early 1980s when Elichi Kono designed a range that included Light, Medium and Bold, each with its italic version. The typesetters P22 developed today's electronic version, sometimes called TfL Johnston, in 1997.^[311]

Posters and patronage of the arts

1913 Underground poster by Tony Sarg

Early advertising posters used various letter fonts.^[312] Graphic posters first appeared in the 1890s,^[313] and it became possible to print colour images economically in the early 20th century.^[314] The Central London Railway used colour illustrations in their 1905 poster,^[315] and from 1908 the Underground Group, under Pick's direction, used images of country scenes, shopping and major events on posters to encourage use of the tube.^[316] Pick found he was limited by the commercial artists the printers used, and so commissioned work from artists and designers such as Dora Batty,^[317] Edward McKnight Kauffer, the cartoonist George Morrow,^[313] Herry (Heather) Perry,^[317] Graham Sutherland,^[313] Charles Sharland^[318] and the sisters Anna and Doris Zinkeisen. According to Ruth Artmonsky, over 150 women artists were commissioned by Pick and latterly Christian Barman to design posters for London Underground, London Transport and London County Council Tramways.^[319]

The Johnston Sans letter font began appearing on posters from 1917.^[318] The Met, strongly independent, used images on timetables and on the cover of its Metro-land guide that promoted the country it served for the walker, visitor and later the house-hunter.^[320][321] By the time London Transport was formed in 1933 the UERL was considered a patron of the arts^[313] and over 1000 works were commissioned in the 1930s, such as the cartoon images of Charles Burton and Kauffer's later abstract cubist and surrealist images.^[322] Harold Hutchison became London Transport publicity officer in 1947, after the Second World War and nationalisation, and introduced the "pair poster", where an image on a poster was paired with text on another. Numbers of commissions dropped, to eight a year in the 1950s and just four a year in the 1970s,^[313] with images from artists such Harry Stevens and Tom Eckersley.^[323]

Artwork by French artist Daniel Buren, commissioned by Art on the Underground at Tottenham Court Road

Art on the Underground was launched in 2000 to revive London Underground as a patron of the arts.^[324] Today, commissions range from the pocket tube map cover, to temporary art pieces, to large scale permanent installations in stations.^[325][326] Major commissions by Art on the Underground in recent years have included Labyrinth by Turner prize winning artist Mark Wallinger to mark the 150th anniversary of the London Underground,^[327] "Diamonds and Circles" permanent works "in situ" by French artist Daniel Buren at Tottenham Court Road^[328] and "Beauty Frank Pick by Langlands & Bell at Piccadilly Circus.^[329]

Similarly since 1986, Poems on the Underground has commissioned poetry that is displayed in trains.^[330]

The Underground (including several fictitious stations^[331]) has been featured in many movies and television shows, including Skyfall, Death Line, Die Another Day, Sliding Doors, An American Werewolf in London, Creep, Tube Tales, Sherlock and Neverwhere. The London Underground Film Office received over 200 requests to film in 2000.^[332] The Underground has also featured in music such as The Jam's "Down in the Tube Station at Midnight" and in literature such as the graphic novel V for Vendetta. Popular legends about the Underground being haunted persist to this day.^[333] In 2016, British composer Daniel Liam Glyn released his concept album Changing Stations based on the 11 main tube lines of the London Underground network.^[334]

Call of Duty: Modern Warfare 3 has a single-player level named Mind The Gap where most of the level takes place between the dockyards and Westminster while the player and a team of SAS attempt to take down terrorists attempting to escape using the London Underground via a hijacked train. The game also features the multiplayer map "Underground", in which players are combating in a fictitious Underground station. The London Underground map serves as a playing field for the conceptual game of Mornington Crescent^[335] (which is named after a station on the Northern line) and the board game The London Game.

In 1999, Carlton Television premiered a regional game show (Greater London area only) also called Mind the Gap.^[336]

Busking

The London Underground provides busking permits for up to 39 pitches across 25 central London stations, with over 100,000 hours of live music performed each year.^[337] Performers are chosen by audition, with previous buskers including Ed Sheeran, George Michael and Rod Stewart.^[338]

Harry Beck

Harry Beck

Henry Charles Beck was an English technical draughtsman who created the present London Underground Tube map in 1931. Beck drew the diagram after being fired at the London Metro Signal Office. Although his design was initially rejected, the Publicity Office of London Transport changed their minds after Beck resubmitted an updated copy and the map was first issued as a pocket edition in January 1933. It was immediately popular, and the Underground has used topological maps to illustrate the network ever since. Harry Beck wanted to make the network easier to understand by colouring each train route and using straight lines and 45 degree angles.

Google Doodle

Google Doodle

A Google Doodle is a special, temporary alteration of the logo on Google's homepages intended to commemorate holidays, events, achievements, and notable historical figures. The first Google Doodle honored the 1998 edition of the long-running annual Burning Man event in Black Rock City, Nevada, and was designed by co-founders Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. Early Marketing employee Susan Wojcicki then spearheaded subsequent Doodles, including an alien landing on Google and additional custom logos for major holidays. Google Doodles were designed by an outside contractor until 2000, when Page and Brin asked public relations officer Dennis Hwang to design a logo for Bastille Day. Since then, a team of employees called "Doodlers" have organized and published the Doodles.

List of Art on the Underground Tube map covers

Since 2004, Art on the Underground has commissioned artists to create covers for London Underground's pocket Tube map. These free maps are one of the largest public art commissions in the UK. Over 35 different designs have been produced, with designs from a wide variety of British and international artists. Around 2 million maps are printed for each cover, down from a high of around 12 million in the early 2010s. In 2014, The Guardian published a pictorial survey of the first 10 years' designs, and The Londonist has a survey up to 2017. Between 2016 and 2018, there were also a series of covers for Night Tube.

London Overground

London Overground

London Overground is a suburban rail network serving London and its environs. Established in 2007 to take over Silverlink Metro routes, it now serves a large part of Greater London as well as the home county of Hertfordshire, with 113 stations on nine different routes.

Docklands Light Railway

Docklands Light Railway

The Docklands Light Railway (DLR) is an automated light metro system serving the redeveloped Docklands area of London, England and provides a direct connection between London's two major financial districts, Canary Wharf and the City of London. First opened on 31 August 1987, the DLR has been extended multiple times, giving a total route length of 38 km. Lines now reach north to Stratford, south to Lewisham, west to Tower Gateway and Bank in the City of London financial district, and east to Beckton, London City Airport and Woolwich Arsenal. Further extensions are being considered.

Crossrail

Crossrail

Crossrail is a railway construction project centred around London. Its aim is to provide a high-frequency hybrid commuter rail and rapid transit system crossing the capital from suburbs on the west to east, by connecting two major railway lines terminating in London: the Great Western Main Line and the Great Eastern Main Line. The project was approved in 2007, and construction began in 2009 on the central section and connections to existing lines that became part of the route, which has been branded the Elizabeth line in honour of Queen Elizabeth II who opened the line on 17 May 2022 during her Platinum Jubilee. The central section of the line between Paddington and Abbey Wood opened on 24 May 2022, with 12 trains per hour running in each direction through the core section in Central London

Conceptual art

Conceptual art

Conceptual art, also referred to as conceptualism, is art in which the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic, technical, and material concerns. Some works of conceptual art, sometimes called installations, may be constructed by anyone simply by following a set of written instructions. This method was fundamental to American artist Sol LeWitt's definition of conceptual art, one of the first to appear in print:In conceptual art the idea or concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.

The London Underground is frequently studied by academics because it is one of the largest, oldest, and most widely used systems of public transit in the world. Therefore, the transportation and complex network literatures include extensive information about the Tube system.

For London Underground passengers, research suggests that transfers are highly costly in terms of walk and wait times. Because these costs are unevenly distributed across stations and platforms, path choice analyses may be helpful in guiding upgrades and choice of new stations.^[339] Routes on the Underground can also be optimized using a global network optimization approach, akin to routing algorithms for Internet applications.^[340] Analysis of the Underground as a network may also be helpful for setting safety priorities, since the stations targeted in the 2005 London bombings were amongst the most effective for disrupting the transportation system.^[341]

Harry Beck

Harry Beck

Henry Charles Beck was an English technical draughtsman who created the present London Underground Tube map in 1931. Beck drew the diagram after being fired at the London Metro Signal Office. Although his design was initially rejected, the Publicity Office of London Transport changed their minds after Beck resubmitted an updated copy and the map was first issued as a pocket edition in January 1933. It was immediately popular, and the Underground has used topological maps to illustrate the network ever since. Harry Beck wanted to make the network easier to understand by colouring each train route and using straight lines and 45 degree angles.
