Whoa, I spotted a rail train tied down between Dover and Denville on #2 track Saturday (04/22/12) around 14:00. They ("Dover Extra") were taking a few cars around the wye seperate from the rail train, pulling west on #1 track to Dover interlocking, then shoving east on #2 track, coupling the car up, then going back (just the 3 engines) and doing it all again with a different car. Passenger trains were running both directions on #1 track. Once that hoopalah was all done, the rail train was then taken someplace in a real hurry. That rail train wasn't parked on the wye, east dover freight, stub, greystone, or UN as of Sunday...
Also I saw it being pulled by 3 engines as well, 4300, 4301 and a 41 series jeep in the lead. That rail train was loooong, no rock boxes either.
Houdini rail train, gotta love it. (Scottish voice) Feed your utility board OT, FEED IT!
