This was taken on the Port Road, during a 1954 PRR excursion train, looking out the back window. Today about 80% of the old PRR signals on this route are still serving, and the Port Line remains a heavy freight tonnage route for the NS, with lots of nighttime traffic account of Amtrak & work windows on the NE corridor during the day. Thanks to rp.net viewer Joe Benson for the caption info.
