The Broad Street Line (BSL), also known as the Broad Street subway (BSS), Orange Line, or Broad Line, is a subway line owned by the city of Philadelphia and operated by the Southeastern Pennsylvania Transportation Authority (SEPTA). The line runs primarily north-south from the Fern Rock Transportation Center in North Philadelphia through Center City Philadelphia to NRG station at Pattison Avenue in South Philadelphia; the latter station provides access to the stadiums and arenas for the city's major professional sports teams at the South Philadelphia Sports Complex, about a quarter mile away. It is named for Broad Street, under which the line runs for almost its entire length. In 2024, as part of the SEPTA Metro plan, the Broad Street Line is expected to be renamed the B Line.

Rapid transit or mass rapid transit (MRT), also known as metro, is a type of high-capacity public transport that is generally built in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways, usually electric, that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles. They are often grade-separated in tunnels or on elevated railways.
The London Underground is the world's first and oldest rapid transit system.
The New York City Subway is the world's largest single-operator rapid transit system by number of metro stations, at 472.
