| The junction at the west end of Rockville bridge was a classic example of PRR grade separation, with tracks on a couple of levels. This one was a good way to "sneak in" a train from the west, on this track that dipped under the west end of the bridge, and avoided some of the conflict that occurred with other simultaneous moves. A new C40-8W leads this train into Enola. Looks like a U23B is the trailing unit. |
