Over 40 years ago I lived in Omaha. Whilst there I managed to wangle a visit to UP’s shops. I took photos I know but can I find them? No way, Jose.
The exhibit you are about to see did not exist when I was there. The vid shows a Big Boy on display. I learned of it courtesy of a heads up from our Club’s (The Mendocino Coast Model Railroad and Historical Society) VP, Lonnie Dickson. Lonnie worked for SP (Southern Pacific) and UP after the merger of the two for his entire career.
Pretty cool eh?
