Train 823 pauses briefly at West Baca on July 23, 1988. The dispatcher gives the crew instruction to stop at Bluewater and assist a mechanic working on the air brake system on engine 901. The train has engines 5087, 5252, 5366, and 8037. Just to the right of the lead locomotive you can see the smoke stack for the Plains Escalante Generating Station.
If you are like me, I am used to signals for a westbound train to be on the north side of the tracks, so this shot may look at bit confusing. You are looking at the back side of the signal just ahead of the train. It is for a westward train. Disk 64
