SR,
The layout was the DSMR's Colorado Midland, now dismantled.
Up on the face of the mesa is a coal mine. The coal was sent down to a bin, where a bull dozier or front loader could load the coal into the conveyor belt, which is what you see, that carries the coal to a load-out. The tracks in the foreground hold hoppers prior to their trip under the load-out.
