I was thinking the Leadville yard but I google earthed it and the yard is mostly gone. I guess the mine shut down and they pulled it up. Looks like just a tourist operation now. And the RR has been severed from the Tenesse pass line in town. Alot of the branch still exists and the yard at California Gulch junction maybe those are possible places.
I noticed two ROWs leaving leadville toward the pit mine, one has track and the other does not. What were those two lines? Im assuming C&S or CM main lines? Dont know much about that area...
