13th Street station (SEPTA)

13th Street (formerly 13th/Juniper Street) is a SEPTA Market-Frankford Line and Subway-Surface Lines station in Philadelphia, Pennsylvania, under Market Street between 13th and Juniper Streets in Center City. The station serves the Market–Frankford Line and as the terminus for all five routes of the Subway–Surface Trolley Lines. Until 2011, it was named the 13th Street stop on the Market–Frankford Line and as the Juniper terminus for the Subway–Surface Trolleys.

The Market–Frankford Line platforms are located one story below ground level, connected to the Center City Commuter Connection concourse. The south concourse, accessible from the eastbound platform, features underground access to SEPTA's headquarters and transit museum, located at 1234 Market Street.

The Subway–Surface trolley platform for Routes 10, 11, 13, 34, and 36 is located two stories below ground level, and is accessible only by escalator or stairway from the Market–Frankford platforms. The station is located at the end of the Subway–Surface Line on a balloon loop located under Juniper Street, and features a single track with all trolleys operating in the same direction. Inbound trolleys discharge passengers on the southernmost portion of the platform. The trolley then proceeds to pick up passengers at either Berth 1 or Berth 2. Routes 10, 11 and 13 board at Berth 1, which is located on the northernmost portion of the platform. Routes 34 and 36 board at Berth 2, which is in the center of the platform. Upon departure of the station, the track wraps around and heads west towards 15th Street station. It also features a short spur track to the northeast that is occasionally used to park stranded or dead trolleys.
