Saw a photo on the Friend's site of #490 pulling an excursion train through Allison, Colorado, so I decided to try recreate the tracks and structures on Google My Maps.

Not sure if that pile of wood is the remains of the Allison Depot, or if the depot was moved or fully demolished. The pile of wood is approximately in the same spot of the depot when you look at the photo. The end of the siding heading to Chama could be longer or shorter, but I never found any photos of it or any maps.
If you have any suggestions/corrections, please feel free to say.
