An extensive number of trolley car lines linked the city of Philadelphia to the rich farmland and picturesque towns of southeastern Pennsylvania. These trolley lines traversed miles of narrow streets lined with row houses whose residents were proud working-class Americans. These historic photographs trace the trolley cars’ routes, including Route 23, the region’s longest urban trolley route, from the expanses of Northwest Philadelphia’s Chestnut Hill through the crowded commercial Center City to South Philadelphia with a variety of neighborhood stops at everything in between. Southeastern Pennsylvania Trolleys follows the history of the trolley cars that have served this diverse and historic region.
