Spring Street (IRT Lexington Avenue Line) - Station Layout

Station Layout

Spring Street is laid out in a typical local stop setup. There are two side platforms and four tracks, the center two of which are express tracks. The southbound local track is technically known as MM1 and the northbound one is MM4; the MM designation is used for chaining purposes along the Lexington Avenue Line from Brooklyn Bridge – City Hall to Times Square – 42nd Street via Grand Central and the 42nd Street Shuttle. Although they cannot be accessed at Spring Street, the southbound and northbound express tracks are known as MM2 and MM3, respectively. These designations are rarely, if ever, used in everyday speech. Both platforms have a slight curve which creates a gap between the train and the platform. Because this gap is not significant, gap fillers are not necessary.

Spring Street had a unique fifth center track which has now been removed. This track did not last long; it was reportedly disconnected and removed in 1906, only two years after the subway opened. Although its function has never been determined, the trackway is now used as the location of a mechanical room.

The station retains the typical large and small IRT mosaics in the old (prior to platform lengthening) portion. The station has small "S" cartouches with two poppies from 1904, made by Atlantic Terra Cotta, and large mosaic tablets by Heins & LaFarge, also from 1904. Other small "S" and "Spring St" mosaics are newer. The "S" cartouches are similar to the ones cast for Canal Street station.
