The Interborough Rapid Transit Company (IRT) was the private operator of New York City's original underground subway line that opened in 1904, as well as earlier elevated railways and additional rapid transit lines in New York City. The IRT was purchased by the city in June 1940, along with the younger BMT and IND systems, to form the modern New York City Subway. The former IRT lines are now the A Division or IRT Division of the Subway.

The Dual Contracts, also known as the Dual Subway System, were contracts for the construction and/or rehabilitation and operation of rapid transit lines in the City of New York. The contracts were signed on March 19, 1913, by the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company. As part of the Dual Contracts, the IRT and BRT would build or upgrade several subway lines in New York City, then operate them for 49 years.

New York, often called New York City or NYC, is the most populous city in the United States. With a 2020 population of 8,804,190 distributed over 300.46 square miles (778.2 km2), New York City is the most densely populated major city in the United States and more than twice as populous as Los Angeles, the nation's second-largest city. New York City is located at the southern tip of New York State. It constitutes the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the U.S. by both population and urban area. With over 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York is one of the world's most populous megacities, and over 58 million people live within 250 mi (400 km) of the city.

Home to the headquarters of the United Nations, New York is an important center for international diplomacy, and is sometimes described as the capital of the world.

A side platform is a platform positioned to the side of one or more railway tracks or guideways at a railway station, tram stop, or transitway. A station having dual side platforms, one for each direction of travel, is the basic design used for double-track railway lines. Side platforms may result in a wider overall footprint for the station compared with an island platform where a single width of platform can be shared by riders using either track.

A turnstile is a form of gate which allows one person to pass at a time. A turnstile can be configured to enforce one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, pass, or other method of payment. Modern turnstiles can incorporate biometrics, including retina scanning, fingerprints, and other individual human characteristics which can be scanned. Thus a turnstile can be used in the case of paid access, for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.
