Delaware & Hudson train PYRP (Potomac Yard – Rouses Point) parallels the Lehigh River through the Lehigh Narrows between Packerton and Jim Thorpe, Pennsylvania. Under operation by the Susquehanna, D&H trains could show up with an almost unlimited combination of power. Today’s train includes a CSX GP40, a Chessie/CSX GP38, and a Susquehanne F45.
