The PATCO Speedline, signed in Philadelphia as the Lindenwold Line and also known colloquially as the PATCO High Speed Line, is a rapid transit route operated by the Port Authority Transit Corporation (PATCO), which runs between Philadelphia, Pennsylvania, and Camden County, New Jersey.

The Delaware River Port Authority (DRPA), officially the Delaware River Port Authority of Pennsylvania and New Jersey, is a bi-state agency instrumentality created by a congressionally approved interstate compact between the state governments of Pennsylvania and New Jersey. The authority is principally charged to maintain and develop transportation links between the two states with four bridges and a mass transit rail line across the Delaware River. Though the DRPA has "port" in its name, it does not own or operate any ports.
