These are scenes from Douglas Wyoming, which is the location of a Railroad Interpretive Center. The old Great Northwestern depot serves as its headquarters, as well as the chamber of commerce's headquarters.
The last photograph is not at the Railroad interpretive center, but is nearby. This is the former Burlington Northern depot, now a restaurant.
Updated on April 28, 2015, from the original March 31, 2012 publication. Most of these photos depict things already photographed, but an old railroad building of some kind, now in use for another purpose, also now appears.
