I've started working on a map of the RG&PS which ran between Lumberton NM and Flaugh CO (just SE of Pagosa Springs). The line was removed around 1916 so it isn't always easy to spot on the aerials. What has been drawn so far is based upon traces found on the topo and visual clues on the aerials. I'm sure that there are a few mistakes along the way so take it for what it is worth. I'm missing a big chunk in the center and the southern part of the route. There were also a few spurs up some of the side canyons.
