After the 483/480 Extra West reached Chama the tank cars were removed and the train was reorganized and dispatched with 481 to what I assume would be Durango. One shot of 483 on Labato Trestle and then a couple shots of 481 leaving Chama on a small bridge (yard can be seen at the rear of the train) and a shot near Monero. I can't make out the markings on the side of the excavators which might help us figure out where they were going. I don't think they are RR equipment, but again it's hard to tell.
