The Wall Street station is a station on the IRT Broadway–Seventh Avenue Line of the New York City Subway, located at the intersection of Wall Street and William Street in the Financial District of Manhattan. It is served by the 2 train at all times and the 3 train at all times except late nights. History The Wall Street station was built on the portion of the IRT Broadway–Seventh Avenue Line built as part of the Dual Contracts, which is the section south of Times Square–42nd Street. The line first opened as a shuttle to 34th Street–Penn Station on June 3, 1917. The line was extended south to South Ferry on July 1, 1918; the Wall Street station opened on the same date, and was the southern terminus of a shuttle on the line's Brooklyn Branch to Chambers Street. On August 1, 1918, the new "H" system was implemented on August 1, 1918, joining the two halves of the Broadway–Seventh Avenue Line and sending all West Side trains south from Times Square. As a result, shuttle service to this station was replaced by through service. This station was the line's terminus until April 15, 1919, when the Clark Street Tunnel opened, allowing service to run to Brooklyn. The city government took over the IRT's operations on June 12, 1940. During the 1964–1965 fiscal year, the platforms at Wall Street, along with those at four other stations on the Broadway–Seventh Avenue Line, were lengthened to 525 feet to accommodate a ten-car train of 51-foot IRT cars. In 1995, as a result of service reductions, the MTA was considering permanently closing one of the two Wall Street stations, as well as two other stations citywide, due to their proximity to each other. Either the IRT Broadway–Seventh Avenue Line station or the IRT Lexington Avenue Line station would have been closed. Station layout This underground station is the southernmost in Manhattan on the Brooklyn Branch of the Broadway–Seventh Avenue Line. South of here, the line travels under the East River via the Clark Street Tunnel to Brooklyn Heights. The single island platform is between the two tracks, and is very narrow compared to other stations in system. It has blue I-beam columns and dark blue floors tiles. The walls by the tracks have small "W" tablets on a mosaic trim except at the north end, where they have "WALL ST" written in black
