Glanford/Esplen to Pittsburgh South Side Junction

From the junction between the Weirton Secondary and the Conrail Mon Line at CP Esplen (MP 2.4), the Mon Line heads southeast, single track, CTC, maximum speed 25 mph, past a former wye on the south side where the erstwhile alternate line from Wagner Tower once connected in, a connection (flat crossing) from the CSX line on the north side at West End, departing on the south side as the CSX line up to West Liberty and beyond, a former bridge that once carried the erstwhile Pittsburgh & West Virginia passenger line overhead, and the former Pittsburgh South Side Junction, where the PRR passenger line once turned across the Monongahela River to reach Penn Station.
