Wheelspur is RR property so be mindful if you try going back there.
3100 should have been gone already. Three weeks ago Frontier was down there loading M3s - they got two loaded but couldn't get the 3100 onto a flat for some reason. Perhaps some trouble with the rental equipment, or the elements (they were loading right after that snow storm). The two M3s they loaded left town last week. Those two didn't come from Arch street, LIRR had those two stashed somewhere else. Not sure what numbers they were.
Greg Grice has a nice photo of 3100 here:

The little tombstones on the side have its former numbers, and the hand painted alco logo adds to it. On the far side there's an inscription: 'the many lives of an American locomotive, blt: 1951, rip 2018'. Nice send 'NY' send off...
