145th Street is a station on the IRT Lenox Avenue Line of the New York City Subway. Located at the intersection of 145th Street and Lenox Avenue in the Harlem neighborhood of Manhattan, it is served by the 3 train at all times. It is landmarked on the National Register of Historic Places.Station layoutThere are two tracks with two short side platforms that accommodate about 6 cars (only the first 5 cars open, because all five cars of each R62 train used on the 3 service must have their doors open at the same time (selective door operation is used)). Even then, only four cars opened up to serve passengers at this station until 2002, as each 3 train ran nine cars per train on the R62A cars.Like the other stations on the original IRT subway, it was initially built for trains shorter in length than the standard eight to ten cars used by the subway. Eventually, all of the other stations were either lengthened or closed, leaving 145th Street as the only original IRT station that still cannot accommodate ten-car trains. Directly north of the station is a diamond crossover for the approach to the northern terminal of the 3 train at Harlem–148th Street. Directly south of the station is the 142nd Street Junction with the IRT White Plains Road Line. The proximity of the switches on both directions is the reason why the station was not lengthened.
