As a Railfan traveling through Colorado in April 2016 we visited the Colorado Railroad Museum, which is in Golden, Colorado.
The Denver HO Model Railroad Club is there also in the basement of the Railroad Station which is a replica similar to the stations along the Denver & Rio Grand Railroad.
We stopped in the city itself to do a little sightseeing. We will add photos to this gallery of our 2013 trip very soon.
