Originating out of Rockport, NJ, the Chesapeake & Delaware's Dover & Rockaway River local train RP2 heads east through Mount Arlington Train Station on Track #1. Behind the leader is DRRV 5304 (GP38-2) which was bought from Norfolk Southern in December of 2020. Earlier, it belonged to Conrail as CR 8119, and before that, it belonged to the Penn Central as PC 8119. The leader originally was built as a GP38 for the Chesapeake & Ohio as CO 3870, before going to CSX as CSXT 2070. It was then rebuilt into a GP38-2 for the Chicago & Northwestern as CNW 4706, then it went to the CIT Group/Capital Finance Inc. as CEFX 404, before going to the Chesapeake & Delaware's Dover & Rockaway River Railroad.
