Thoughts was is going in this unusual photo? Was the Pooch so ugly they made it run backwards?
After I typed that, I found the full story in the description. I will post it under the photo.

"...Amtrak's westbound "Sunset Ltd." at Lordsburg, New Mexico on September 10, 1985. The lead locomotive has been damaged and had to be set out en route; the train was brought into town by a single "Pooch" running backwards. An SP unit will be added here for the trip west. Photo by David Rector."
Without that description, I doubt anyone would have correctly guessed what really happened.
