[?]Looking for drawings and/or photos of the Pueblo Colorado Union Station as it appeared around 1953.[?]
Chevypanel52,
Did a Google search and found a heritage center is now in the Union Station at Pueblo:
http://www.se-colorado-heritage.org/
Suggest you click on the link, and then use their contact link to learn what they have in the way of photos and plans. There is also at least one postcard view of the station available according to the same Google search results. Possibly someone else knows of a Web site specializing in depots and stations. Another possibility is the “fallen flags” Web site.
