That station belonged the Denver, Utah & Pacific Railroad. This line was Moffat's first attempt to build a line due west out of Denver. It has kind of an odd history as the "Branch Line" from Denver to Lyons was built first and the main line from Hallack Jct (about 100th and Wadsworth Blvd) to Salt Lake City via (get this) Rollins Pass, Granby, and Rangely, Colo. The line was surveyed but never built. Their proposed main line missed Grand Junction completely. The DU&P was purchased by the CB&Q and Standard gauged using he old roadbed of the UP subsidiary the Denver, Western & Pacific Railroad from Burns Junction (just west of Broomfied) via Lafayette, Erie and Idaho Creek into Longmont. This depot was also used for many years by the CB&Q as a freight office which is why it survived so long. I remember rattling by it when I was about 18 when a friend of mine (who was a CB&Q engineer) took me for a ride on the "Buckwheat Branch", which is what the branch to Lyons was known as. The depot was still being used by the CB&Q then for MOW.
