The Newark Subway operates out of the lower level, the entrance to which is located in the extreme northeast corner of the station. Stairs descend to an intermediate level where there is a old wooden token booth and artwork in bronze of subway riders. This artwork is entitled The Commuters by Gregory Gurevich and was installed in 1994. Passengers exiting the station use an escalator which bypasses this intermediate level directly to the Pennsylvania Station concourse at street level. Only the two side platforms are used for regular passenger service.
Lighting is fluorescent and walls are tan tile.
The station area serves as the main maintenance shops for the 1940s-era PCC vehicles of the City Subway. Between the side platform areas is a maintenance shop and small yard for storage of the trolleys. At the south end of the station are two loops for turning the cars. New Jersey Transit indicated that the outer loop has an 82 foot turning radius and the inner loop has a 62 foot turning radius. Check the Track Map for details.
