8th Street station is a subway station complex in Philadelphia, Pennsylvania, located at the intersection of 8th Street and Market Street in Center City. It is served by SEPTA's Market–Frankford and Broad–Ridge Spur lines, as well as the PATCO Speedline (signed by SEPTA as the "Lindenwold Line"). The entire complex is owned by SEPTA, while the PATCO areas are leased by the Port Authority Transit Corporation, which operates that line. 8th Street is the only station in Philadelphia where these three subway lines interchange.
