SEPTA's Trolley Route 56, the Erie and Torresdale Avenues Line, is a former streetcar line that is now served by bus. It is operated by the Southeastern Pennsylvania Transportation Authority (SEPTA) in Philadelphia, Pennsylvania, United States. The line runs between the Tioga and Tacony neighborhoods primarily along Erie Avenue and Torresdale Avenue. Route 56 was one of three "suspended" by the SEPTA board effective June 12, 1992. The two others, Routes 15 and 23, were then also operated by buses as of the same year; however, the Route 15 Trolley has since been restored back to trolley as of September 5, 2005.
