Located at the intersection of Broadway and 225th Street in the Marble Hill neighborhood of Manhattan, it is served by the 1 train at all times.[3] To address overcrowding, in 1909, the New York Public Service Commission proposed lengthening the platforms at stations along the original IRT subway.[4]: 168 As part of a modification to the IRT's construction contracts made on January 18, 1910, the company was to lengthen station platforms to accommodate ten-car express and six-car local trains.[14] From August 21, 1989 to May 27, 2005 this was one of three (originally four) stations served by only the 9 train during rush hours (as well as middays before September 4, 1994), when skip stop service was operating.Access to and from the northbound platform is via two full-height turnstiles, one exit-only and the other entry-exit, and one staircase going down to the east side of Broadway across from the northwest corner of 225th Street.This station today and the neighborhood it serves reside on the north shore of the Harlem River Ship Canal, also known as Spuyten Duyvil Creek, and are thus geographically on the mainland.
