It is located underneath Market Street in Center City Philadelphia, and serves all routes of the SEPTA subway–surface trolley lines.

The station was built by the Philadelphia Rapid Transit Company (PRT), and for the first two years formed part of a subway–surface trolley loop operating underground between 15th Street and the Schuylkill River.

The PRT bridge connected trolley lines in West Philadelphia to the underground subway–surface loop in Center City.

Since Route 31’s routing was hit the most with line running on Market Street, PTC converted the line into a West Philadelphia Shuttle from 46th & Market Streets to 70th & Lansdowne until conversion to bus on June 19, 1956.

Route 38 was converted to bus on the same day the eastbound portion of the subway extension opened on October 15, 1955.
