 The inner track existed when the station was built, but only as a storage track.When the "H" system of the IRT opened on July 1, 1918, Broadway–Seventh Avenue Line trains used the outer platform while the inner platform was opened for IRT Lexington Avenue Line trains which used the original trunk line in Lower Manhattan.Only the end doors of each car of the five-car trains could platform at the station, because of the large gap between the middle doors and the platform, owing to the severe curve of the station.
