The local portion of the Broad Street Line carries a headway of eight minutes or less during the daytime all day weekdays, 10–12 minutes all day on weekends and major holidays, and 12 minutes in the evenings. Weekend night service consists of a 20-minute frequency, while owl bus service early weekday mornings utilize a 15-minute frequency.

Broad–Ridge Spur 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). Ridge Spur service to 8th and Market streets began on December 21, 1932. As part of that project, a tunnel shell running south under 8th Street then west under Locust Street to 18th Street (reusing parts of the never-completed Center City loop constructed in 1917) was completed in 1933 but not outfitted for service. Bridge Line service from 8th and Market to Camden began on June 7, 1936, sharing the Ridge Spur platforms at 8th and Market and splitting off from the Ridge Spur just south of Chinatown station. Beginning in June 1949, Ridge Spur and Bridge Line trains were through-routed at 8th and Market. The unused Locust Street tunnel was completed on February 15, 1953; Bridge Line trains were extended to a new terminus at 15th–16th Street station with two intermediate stops, while Ridge Spur trains reverted to running between 8th Street and Girard. In January 1954, due to low ridership, off-peak service and Saturday again began operating between Girard and Camden, with a shuttle train operating between 8th and 16th stations. Sunday service was suspended at that time due to minimal usage. Ridge Spur service was suspended from August 23 to
