8th–Market station

8th–Market station is a rapid transit station complex at the intersection of 8th Street and Market Street in Center City neighborhood of Philadelphia, Pennsylvania. It is served by SEPTA Metro's L and B3 trains, as well as the PATCO Speedline. It is the only station where these three lines intersect. The entire complex is owned by the City of Philadelphia, with the Delaware River Port Authority (owner of PATCO) and SEPTA leasing space for operations.

The station complex comprises three platforms, one for the L line, one for the B3 line, and the 8th & Market station on the PATCO Speedline. These are arranged across three underground levels. The upper mezzanine level spans above the L line tracks, the middle level accommodates the east-west-running L line and the northbound B3 line, and a lower level serving the PATCO Speedline, which runs north–south. Each platform has fare control and entrances/exits, though they are connected via the shared mezzanine level.

For much of the 20th century, the corner of 8th and Market was a retail hub for the city, home to major department stores including Strawbridge's, Gimbels and Lit Brothers, all of which had direct access to the station complex. Today, that underground connection serves the Fashion District Philadelphia shopping mall, which offers indirect access to SEPTA Regional Rail at Jefferson Station, as well as connections to the B line via the Downtown Link concourse.
