History.
The station opened on September 10, 1932, as part of the city-operated Independent Subway System (IND)'s initial segment, the Eighth Avenue Line between Chambers Street and 207th Street.
In 1981, the MTA listed the station among the 69 most deteriorated stations in the subway system. The station was renovated in the 1980s, during which two stairs to each platform at the north end were removed and the platforms' original white floor tiling was replaced. The station was damaged in a water main break in 1989. Another renovation later restored the closed staircases and made the station ADA-accessible with the installation of elevators near the middle of the platforms.
On June 27, 2017, a southbound A train derailed just north of the station. This derailment, caused by improperly secured replacement rails, left 34 passengers injured.
Station layout.
The outer track wall tiles have a Prussian green trim line with a black border with small "125" signs in white lettering on a black background beneath it. Both platforms have one line of green I-beam columns that run at regular intervals for their entire length except for a small section at either ends. Every other column has the standard black station name plate in white lettering.
The station has a mezzanine above the tracks at the Southern end and platforms that connect both fare control areas at either ends. There are five staircases to each platform and large-scale photos of Harlem in the 1920s and 1930s.
The next express station to the south, 59th Street–Columbus Circle, is 3.35 miles (5.391 km) away with seven local stations in between, which is the longest distance between two express stops in the system.
Exits.
The full-time fare control area is at the south end of the mezzanine, serving the 125th Street exits, and has a turnstile bank and token booth. It serves the exits at St. Nicholas Avenue and West 125th Street. The other fare control area at the north end, serving the 127th Street exits, is unstaffed, containing full height turnstiles. There is also evidence of closed exit stairs going up to 126th Street and 124th Street, one on each side of both mezzanines. One of the staircases led directly into the basement of a business that existed at street level.
