New York City Subway
The New York City Subway is a rapid transit system in New York City, serving four of the city's five boroughs: Manhattan, Brooklyn, Queens, and the Bronx. It is owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the state-run Metropolitan Transportation Authority. Opened on October 27, 1904, the New York City Subway is one of the world's oldest public transit systems, one of the most-used, and the one with the most stations, with 472 stations in operation.
The system has operated 24/7 service every day of the year throughout most of its history, barring emergencies and disasters. By annual ridership, the New York City Subway is the busiest rapid transit system in both the Western Hemisphere and the Western world, as well as the ninth-busiest rapid transit rail system in the world. The subway carried unlinked, non-unique riders in. Daily ridership has been calculated since 1985; the record, over 6.2 million, was set on October 29, 2015.
The system is also one of the world's longest. Overall, the system consists of of routes, comprising a total of of revenue track and a total of including non-revenue trackage. Of the system's routes or "services", pass through Manhattan, the exceptions being the train, the Franklin Avenue Shuttle, and the Rockaway Park Shuttle. Large portions of the subway outside Manhattan are elevated, on embankments, or in open cuts, and a few stretches of track run at ground level; 40% of track is above ground. Many lines and stations have both express and local services. These lines have three or four tracks. Normally, the outer two are used by local trains, while the inner one or two are used by express trains.
, the New York City Subway's budgetary burden for expenditures was $8.7 billion, supported by collection of fares, bridge tolls, and earmarked regional taxes and fees, as well as direct funding from state and local governments.
History
built the first demonstration for an underground transit system in New York City in 1869 and opened it in February 1870. His Beach Pneumatic Transit only extended under Broadway in Lower Manhattan operating from Warren Street to Murray Street and exhibited his idea for an atmospheric railway as a subway. The tunnel was never extended for political and financial reasons. Today, no part of this line remains as the tunnel was completely within the limits of the present-day City Hall station under Broadway. The Great Blizzard of 1888 helped demonstrate the benefits of an underground transportation system. A plan for the construction of the subway was approved in 1894, and construction began in 1900. Even though the underground portions of the subway had yet to be built, several above-ground segments of the modern-day New York City Subway system were already in service by then. The oldest structure still in use opened in 1885 as part of the BMT Lexington Avenue Line in Brooklyn and is now part of the BMT Jamaica Line. The oldest right-of-way, which is part of the BMT West End Line near Coney Island Creek, was in use in 1864 as a steam railroad called the Brooklyn, Bath and Coney Island Rail Road.The first underground line of the subway opened on October 27, 1904, almost 36 years after the opening of the first elevated line in New York City. The subway line, then called the "Manhattan Main Line", ran from City Hall station northward under Lafayette Street and Park Avenue before turning westward at 42nd Street. It then curved northward again at Times Square, continuing under Broadway before terminating at 145th Street station in Harlem. Its operation was leased to the Interborough Rapid Transit Company, and over 150,000 passengers paid the 5-cent fare to ride it on the first day of operation.
By the late 1900s and early 1910s, the lines had been consolidated into two privately owned systems, the IRT and the Brooklyn Rapid Transit Company. The city built most of the lines and leased them to the companies. The first line of the city-owned and operated Independent Subway System opened in 1932. This system was intended to compete with the private systems and allow some of the elevated railways to be torn down but stayed within the core of the city due to its small startup capital. This required it to be run 'at cost', necessitating fares up to double the five-cent fare of the time, or 10¢.
In 1940, the city bought the two private systems. Some elevated lines ceased service immediately while others closed soon after. Integration was slow, but several connections were built between the IND and BMT. These now operate as one division, called the B Division. Since the former IRT tunnels are narrower, have sharper curves, and shorter station platforms, they cannot accommodate B Division cars, and the former IRT remains its own division, the A Division. Many passenger transfers between stations of all three former companies have been created, allowing the entire network to be treated as a single unit.
During the late 1940s, the system recorded high ridership, and on December 23, 1946, the system-wide record of 8,872,249 fares was set.
The New York City Transit Authority, a public authority of New York City, was created in 1953 to take over subway, bus, and streetcar operations from the city, and placed under control of the state-level Metropolitan Transportation Authority in 1968.
Organized in 1934 by transit workers of the BRT, IRT, and IND, the Transport Workers Union of America Local 100 remains the largest and most influential local of the labor unions. Since the union's founding, there have been three union strikes over contract disputes with the MTA: 12 days in 1966, 11 days in 1980, and three days in 2005.
By the 1970s and 1980s, the New York City Subway was at an all-time low. Ridership had dropped to 1910s levels, and graffiti and crime were rampant. Maintenance was poor, and delays and track problems were common. Still, the NYCTA managed to open six new subway stations in the 1980s, make the current fleet of subway cars graffiti-free, as well as order 1,775 new subway cars. By the early 1990s, conditions had improved significantly, although maintenance backlogs accumulated during those 20 years are still being fixed today.

Entering the 21st century, progress continued despite several disasters. The September 11 attacks resulted in service disruptions on lines running through Lower Manhattan, particularly the IRT Broadway–Seventh Avenue Line, which ran directly underneath the World Trade Center. Sections of the tunnel, as well as the Cortlandt Street station, which was directly underneath the Twin Towers, were severely damaged. Rebuilding required the suspension of service on that line south of Chambers Street. Ten other nearby stations were closed for cleanup. By March 2002, seven of those stations had reopened. Except for Cortlandt Street, the rest reopened in September 2002, along with service south of Chambers Street. Cortlandt Street reopened in September 2018.
In October 2012, Hurricane Sandy flooded several underwater tunnels and other facilities near New York Harbor, as well as trackage over Jamaica Bay. The immediate damage was fixed within six months, but long-term resiliency and rehabilitation projects continued for several years. The recovery projects after the hurricane included the restoration of the new South Ferry station from 2012 to 2017; the full closure of the Montague Street Tunnel from 2013 to 2014; and the partial 14th Street Tunnel shutdown from 2019 to 2020. Annual ridership on the New York City Subway system, which totaled nearly 1.7 billion in 2019, declined dramatically during the COVID-19 pandemic and did not surpass one billion again until 2022.
Construction methods
When the IRT subway debuted in 1904, the typical tunnel construction method was cut-and-cover. The street was torn up to dig the tunnel below before being rebuilt from above. Traffic on the street above would be interrupted due to the digging up of the street. Temporary steel and wooden bridges carried surface traffic above the construction.Contractors in this type of construction faced many obstacles, both natural and human-made. They had to deal with rock formations and groundwater, which required pumps. Twelve miles of sewers, as well as water and gas mains, electric conduits, and steam pipes had to be rerouted. Street railways had to be torn up to allow the work. The foundations of tall buildings often ran near the subway construction, and in some cases needed underpinning to ensure stability.
This method worked well for digging soft dirt and gravel near the street surface. Tunnelling shields were required for deeper sections, such as the Harlem and East River tunnels, which used cast-iron tubes. Rock or concrete-lined tunnels were used on segments from 33rd to 42nd streets under Park Avenue; 116th to 120th Streets under Broadway; 145th to Dyckman Streets under Broadway and St. Nicholas Avenue; and 96th Street and Broadway to Central Park North and Lenox Avenue.
About 40% of the subway system runs on surface or elevated tracks, including steel or cast-iron elevated structures, concrete viaducts, embankments, open cuts and surface routes., there are of elevated tracks. All of these construction methods are completely grade-separated from road and pedestrian crossings, and most crossings of two subway tracks are grade-separated with flying junctions. The sole exceptions of at-grade junctions of two lines in regular service are the 142nd Street and Myrtle Avenue junctions, whose tracks intersect at the same level, as well as the same-direction pairs of tracks on the IRT Eastern Parkway Line at Rogers Junction.
The 7,700 workers who built the original subway lines were mostly immigrants living in Manhattan.
More recent projects use tunnel boring machines, which increase the cost. However, they minimize disruption at street level and avoid already existing utilities. Examples of such projects include the extension of the IRT Flushing Line and the IND Second Avenue Line.
