It operated a citywide system of bus, trolley, and trackless trolley routes, the Market–Frankford Line (subway-elevated rail), the Broad Street Line (subway), and the Delaware River Bridge Line (subway-elevated rail to City Hall, Camden, New Jersey, and now part of the PATCO Speedline) which became SEPTA's City Transit Division.
PTC operated the rapid transit lines in urban Philadelphia – principally the Market–Frankford Line and Broad Street Line – leasing their fixed infrastructure from the City of Philadelphia.
