Well, I was wondering if there are any freights using the ac rail line, because when riding from Cherry Hill To Philly, there are Tracks protruding from the main track before I reach Pennsylvania. If it isn't frieght, what are those extra tracks used for?
Freight trains can use the NJT AC line between the Delair Bridge and the Pemberton Branch.
Closer to Atlantic City, Southern Railroad of NJ freight trains use the NJT AC line between Winslow Junction and Pleasantville.
I photographed the Ringling Brothers circus train being hauled to Pleasantville by SRNJ on NJT (former PRR) at Winslow, after Conrail had delivered it to SRNJ at Winslow on the Conrail track (former Reading).
