This is the end of the line and the customer served is Dupont ( Chambers Works ) . This location is also home to the Carneys Point CoGen plant , they receive coal train from NS and sometimes CSX. It changes so much it's hard to keep track . https://en.wikipedia.org/wiki/Penns_Grove_Secondary#Route Pennsgrove Secondary runs for approximately 20 miles between its it southern terminus at PennsGrove and Woodbury at the north where it joins the Vineland Secondary about 8.5 miles south of Pavonia Yard in Camden. At its southern end the Deepwater Point Running Track continues another 3.7 miles through Carneys Point to Deepwater. Located within Gloucester County and Salem County, the PennsGrove Secondary serves industries and distribution facilities in the corridor along the east bank of the Delaware River and with spur lines to Pureland Industrial Complex and maritime facilities, including the Port of Paulsboro, where rail interchange is provided by SMS Rail Lines. At the north, the line begins in Woodbury at a junction with the Salem Secondary and the Vineland Secondary. It then passes through Thorofare, West Deptford, Paulsboro, Gibbstown, Repaupo, Bridgeport, Pedricktown, and Penns Grove. For much of its length it travels parallel to US Route 130 and New Jersey Route 44. It bridges Mantua Creek, Repaupo Creek, White Sluice Race, Starrs Ditch, Raccoon Creek, and Oldmans Creek. Some of the bridges have been automated. South of PennsGrove, the Deepwater Point Industrial Track continues through Carneys Point to a DuPont industrial complex known as the Chamber Works at Deepwater in the vicinity of the vehicular Delaware Memorial Bridge.
