A two-track spur of the Broad Street Line, known as the Broad–Ridge Spur, diverges from the main line at Fairmount. Originally known as the Ridge–8th Street subway, the line follows Ridge Avenue, southeastward from the intersection of Broad Street, Ridge and Fairmount Avenues to a two-level junction beneath 8th and Race Streets, where tunnels leading to and from the Benjamin Franklin Bridge to Camden connect to it, then proceeds south under 8th Street. At its southern terminus at 8th and Market streets, passengers may transfer to the Market-Frankford Line and the PATCO Speedline. The spur operates Mondays through Saturdays from 6 am to 9 pm, running two-car trains (though platforms can fit five cars).
