We stopped in Dolores, CO more because of the pretty drive up there than its reputation as an old center of the arts. It is also one of the loci of train entusiasts. This odd item of trainiana originally was driven by a Pierce-Arrow inline-6, but now has a more modern engine from the 1930's.
The local train museum is small, but well focused on its local scene. They are trying to get the right-of-way back to run a tourist line up to connect to the Silverton through another legacy canyon route. The sticking point is some of the townies who now hold the land that the rails once ran through.
