Brooklyn–Manhattan Transit Corporation in the context of "Dual Contracts"

The New York City Subway is a rapid transit system that serves four of the five boroughs of New York City, New York: the Bronx, Brooklyn, Manhattan, and Queens. Its operator is the New York City Transit Authority, which is itself controlled by the Metropolitan Transportation Authority of New York. In 2015, an average of 5.65 million passengers used the system daily, making it the busiest rapid transit system in the United States and the 11th busiest in the world.

The present New York City Subway system is composed of three formerly separate systems that merged in 1940: the Interborough Rapid Transit Company (IRT), the Brooklyn–Manhattan Transit Corporation (BMT), and the Independent Subway System (IND). The privately held IRT, founded in 1902, constructed and operated the first underground railway line in New York City. The opening of the first line on October 27, 1904, is commonly cited as the opening of the modern New York City Subway, although some elevated lines of the IRT and BMT that were initially incorporated into the New York City Subway system but then demolished predate this. The oldest sections of elevated lines still in operation were built in 1885. The BMT, founded in 1923 and also privately held, was formed from the bankruptcy of the Brooklyn Rapid Transit Company. The IND was created by the City of New York in 1921 to be a municipally owned competitor of the two private companies. Unification in June 1940 by the New York City Board of Transportation brought the three systems under one operator. The New York City Transit Authority, created in 1953 to be a public benefit corporation that acquired the rapid transit and surface line (buses and streetcars) infrastructure of the Board of Transportation, remains the operator of the New York City Subway today.

The Jackson Heights–Roosevelt Avenue/74th Street station is a New York City Subway station complex served by the IRT Flushing Line and the IND Queens Boulevard Line. Located at the triangle of 74th Street, Broadway, and Roosevelt Avenue in Jackson Heights, Queens, it is served by the 7, E, and F trains at all times; the R train at all times except late nights; the M train on weekdays during the day; and the <F> train during rush hours in the reverse peak direction.

The complex consists of two stations: the elevated station at Broadway–74th Street, built for the Interborough Rapid Transit Company (IRT) and Brooklyn Rapid Transit Company (BRT), and the underground IND station at Jackson Heights–Roosevelt Avenue, built for the Independent Subway System (IND). The elevated station was built as part of the Dual Contracts and opened on April 21, 1917; the station was also served by the BRT and its successor, the Brooklyn–Manhattan Transit Corporation, until 1949. The IND station opened on August 19, 1933, and was the terminus of the Queens Boulevard Line until 1936. Escalators between the two stations were installed in the 1950s, and the complex was substantially rebuilt between 2000 and 2005.

The IND Culver Line (formerly BMT Culver Line) is a rapid transit line of the B Division of the New York City Subway, extending from Downtown Brooklyn south to Coney Island, Brooklyn, New York City, United States. The local tracks of the Culver Line are served by the F service, as well as the G between Bergen Street and Church Avenue. The express tracks north of Church Avenue are used by the <F> train during rush hours in the peak direction. The peak-direction express track between Ditmas Avenue and Avenue X has not seen regular service since 1987.

The line is named after Andrew Culver, who built the original Culver Line that preceded the current subway line. The present-day line was built as two unconnected segments operated by the Independent Subway System (IND) and Brooklyn–Manhattan Transit Corporation (BMT). The northern section of the line, between Jay Street–MetroTech and Church Avenue, is a four-track line that was built for the IND in 1933, running primarily underground except for a short elevated section over the Gowanus Canal.

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 on June 12, 1940, along with the younger BMT and IND systems, to form the modern New York City Subway. The former IRT lines (the numbered routes in the current subway system) are now the A Division or IRT Division of the Subway.

The Independent Subway System (IND; formerly the ISS) was a rapid transit rail system in New York City that is now part of the New York City Subway. It was first constructed as the Eighth Avenue Line in Manhattan in 1932. It was originally also known as the Independent City-Owned Subway System (ICOSS) or the Independent City-Owned Rapid Transit Railroad (ICORTR).

One of three subway networks that became part of the modern New York City Subway, the IND was intended to be fully owned and operated by the municipal government, in contrast to the privately operated or jointly funded Interborough Rapid Transit Company (IRT) and Brooklyn–Manhattan Transit Corporation (BMT) companies. It was merged with these two networks when the subway system was unified in 1940.

The Brooklyn Rapid Transit Company (BRT) was a public transit holding company formed in 1896 to acquire and consolidate railway lines in Brooklyn and Queens, New York City, United States. It was a prominent corporation and industry leader using the single-letter symbol B on the New York Stock Exchange.

It operated both passenger and freight services on its rail rapid transit, elevated and subway network, making it unique among the three companies which built and operated subway lines in New York City. It became insolvent in 1919. It was restructured and released from bankruptcy as the Brooklyn–Manhattan Transit Corporation in 1923.

The IRT Flushing Line is a rapid transit route of the New York City Subway system, named for its eastern terminal in Flushing, Queens. It is operated as part of the A Division. The Interborough Rapid Transit Company (IRT), a private operator, had constructed the section of the line from Flushing, Queens, to Times Square, Manhattan between 1915 and 1928. A western extension was opened to Hudson Yards in western Manhattan in 2015, and the line now stretches from Flushing to Chelsea, Manhattan. It carries trains of the 7 local service, as well as the express <7> during rush hours in the peak direction. It is the only currently operational IRT line to serve Queens.

It is shown in the color purple on station signs, the official subway map, and internal route maps in R188 cars. Before the line was opened all the way to Flushing in 1928, it was known as the Corona Line or Woodside and Corona Line. Prior to the discontinuation of BMT services in 1949, the portion of the IRT Flushing Line between Times Square and Queensboro Plaza was known as the Queensboro Line. Since the mid-2010s, the line's signal system has been converted to an automated system.

The Times Square–42nd Street station is a major New York City Subway station complex located under Times Square, at the intersection of 42nd Street, Seventh Avenue, and Broadway, in Midtown Manhattan. The complex allows free transfers between the IRT 42nd Street Shuttle, the BMT Broadway Line, the IRT Broadway–Seventh Avenue Line and the IRT Flushing Line, as well as to the IND Eighth Avenue Line a block west at 42nd Street–Port Authority Bus Terminal. The complex is served by the 1, 2, 3, 7, N and Q trains at all times, the W train during weekdays; the R and 42nd Street Shuttle (S) trains at all times except late nights; and <7> trains during rush hours in the peak direction. A free passageway from the shuttle platform to the 42nd Street–Bryant Park/Fifth Avenue station, served by the 7, <7>​​, B, ​D, ​F, <F>, and ​M trains, is open during the day from 6 a.m. to 12 a.m.

The present shuttle platforms were built for the Interborough Rapid Transit Company (IRT) as a local station on the city's first subway line, which was approved in 1900. The station opened on October 27, 1904, as one of the original 28 stations of the New York City Subway. As part of the Dual Contracts between the IRT and the Brooklyn–Manhattan Transit Corporation (BMT), the Broadway–Seventh Avenue Line platforms opened in 1917, followed by the Broadway Line platforms in 1918 and the Flushing Line platforms in 1928. The original platforms were also reconfigured to serve the shuttle. The complex has been reconstructed numerous times over the years. The free transfer between the IRT and BMT opened in 1948, while the transfer to the IND station was placed within fare control in 1988. The complex was placed on the National Register of Historic Places in 2004. In the early 21st century, the shuttle station was reconfigured.
