The Center City Commuter Connection, commonly referred to as "the commuter tunnel", is a passenger railroad tunnel in Center City, Philadelphia, Pennsylvania, built to connect the stub ends of the two separate regional commuter rail systems, originally operated by two rival railroad companies: the Pennsylvania Railroad and the Reading Railroad. All of the SEPTA Regional Rail lines except for the Cynwyd Line pass completely through the four-track tunnel, which contains two underground stations - Suburban Station and Market East Station, and the above-ground upper-level concourse for the east-west commuter lines serving 30th Street Station.
