This underground station, opened on July 1, 1933, has two side platforms and three tracks. The center track is used by the D express train during rush hours in peak direction. Both platforms have an orange trim line with a black border and "155" in small white lettering on a black border underneath. The name tablets have "155TH ST. – 8TH AVE." in white sans serif lettering on a black background and green border on them. Yellow I-beam columns run along both platforms at regular intervals, with alternating ones having the standard black name plate in white lettering. The street staircase is wider than normal staircases, since the Polo Grounds stadium, home of the former New York Giants, was situated near the station, before the team left for San Francisco in 1958. The stadium was demolished in 1964 to make way for public housing after the New York Mets played there in 1962 and 1963. Today, Rucker Park is located at the entrance of the station. An abandoned tower sits on the south end of the Brooklyn-bound platform. When the IRT Ninth Avenue Line and later the Polo Grounds Shuttle were in service, there was a provision for transfer tickets between the IND underground level and the IRT elevated shuttle level. A very steep walk was needed to make this transfer. This is the only station in Manhattan that is served solely by the IND Concourse Line. To the north, the line continues under the Harlem River towards 161st Street–Yankee Stadium in the Bronx. To the south, the line continues under Saint Nicholas Place to a transfer station with the IND Eighth Avenue Line at 145th Street. South of 145th Street, the IND Concourse Line merges with the IND Eighth Avenue Line.
Exit
This station has a full length mezzanine above the platforms. However, only the northern end is open and has six staircases to the platforms. The Brooklyn-bound platform has four closed staircases while the Bronx-bound one has five. The mezzanine has yellow I-beam columns. The fare control area at the north end has a turnstile bank, token booth, one exit-only turnstile on each side of the mezzanine, and a quadruple-wide staircase diagonal to the mezzanine that goes up to the west side of Frederick Douglass Boulevard between 155th Street and Harlem River Drive.
