The Subway-Surface Lines are five trolley car routes that are operated by the Southeastern Pennsylvania Transportation Authority. They run along surface tracks in West Philadelphia and parts of Delaware County, Pennsylvania, and within a shared subway tunnel that runs eastward directly towards Center City Philadelphia. The eastern teminus for all five routes is 13th and Juniper Streets.
The Subway-Surface Lines have been likened to trolley lines such as Boston's Green Line.
