Maybe not the right forum to post in, but I have a questions. I have seen various pictures from the mid to late 1970s, prior to the CC Commuter Tunnel, of Reading MUs running on Pennsy rails. My question is how did they get there?! Did they use the Swampoodle connection, or did they get there in some other fashion?
Most likely the connection at N. Philly. Another route would be down the Blue line to via Falls jct to the Belmont branch
and across the K ladder at Zoo for the West end of Powelton yard.
