Pittsburgh South Side Junction to Pittsburgh Penn Station

From the former Pittsburgh South Side Junction, where the PRR passenger line once turned across the Monongahela River to reach Penn Station, the erstwhile line turned north-northeast, bridging over the CSX track along the west bank of the Monongahela River and then over that river, turning north in tunnel below the streets of Pittsburgh, and turning northeast to emerge from that tunnel on the south side platforms at Pittsburgh Penn Station, before joining into the PRR Harrisburg line east of that station.

This right-of-way is now used by the Pittsburgh Light Rail system.
