Preserved Colorado & Wyoming Railroad locomotive simulator car used for training purposes. The Pueblo Railway Museum. Pueblo Colorado USA. 2011., a photo by Eddie from Chicago on Flickr.
My Cousin Allen took this photo, during a recent road trip to Pueblo Colorado.
This unique railroad car, appears to have started it's working life as an ordinary railroad caboose, and was retired as a diesel locomotive simulator car for railroad training purposes on the Colorado & Wyoming Railroad.
Today, it is a museum gift shop building on wheels, at the Pueblo Railway Museum.
