I was just up on the Denver Public Library / Western History site and found many photos of Cumbres Pass
Try a search for D&RGW Cumbres. You can see the west end of the coal building (snow shed) in photo OP-8901.
I did not find the Car inspectors house with this search but I know I saw one with a D&GRW search the other day.
Hope this is of some help.
On the same note, if any one has historic photos of signs on the C&TS I would like to get a copy. We were able to replace the Coxo sign in its historic location because to two photos we found.
