The Southeastern Pennsylvania Transportation Authority, abbreviated as SEPTA, is a regional public transportation authority that operates bus, rapid transit, commuter rail, light rail, and electric trolleybus services for nearly four million people throughout five counties in and around Philadelphia, Pennsylvania. It also manages projects that maintain, replace, and expand its infrastructure, facilities, and vehicles.
SEPTA is the major transit provider for Philadelphia and four surrounding counties within the Philadelphia metropolitan area, including Delaware, Montgomery, Bucks, and Chester counties. It is a state-created authority, with the majority of its board appointed by the five counties it serves. Several SEPTA commuter rail and bus services serve New Castle County, Delaware and Mercer County, New Jersey, although service to Philadelphia from South Jersey is provided by the PATCO Speedline, which is run by the Delaware River Port Authority, a bi-state agency, and NJ Transit, which operates many bus lines and a commuter rail line to Philadelphia.
