Collection Introduction Minimize
These venerable old trains exist today because of the hard work and dedication of a relatively small number of people.  It all began in 1961 when the founders of our museum realized that not only had the era of luxurious steam powered passenger trains come to a close, but little even remained of their existence.  Over the next several years, they set out to save what precious few pieces of equipment were left.  Some were graciously donated by the railroads upon retirement; others were literally pulled from the scrap lines.  These are the survivors – the lucky ones – perhaps a little rough but they are tangible evidence of our heritage. 

Pullman Sleeping Car "Goliad" arrives at the Age of Steam, 1965. A new generation of committed individuals is working to steward this museum into the next century.  But such an endeavor is not an easy one.  Historic preservation often faces challenging circumstances.  We’re constantly seeking additional sources of support as we carry out our mission.  We do our best to maintain the collection and minimize the effects of time and exposure.  We do this in an effort to preserve an important part of history along with a sense of pride in our community. 

There are many stories behind the iron and steel artifacts that are gathered here.  They have undoubtedly touched many lives.  We hope you enjoy your visit.  While some of you will relive the past, others will discover it for the first time.  This collection is part of your heritage.  If you leave here more enlightened and enriched, then we consider our efforts to have been a success.

Union Pacific Steam Locomotive "Big Boy" 4018

Build Date: December, 1941
Builder: ALCO, Schenectady, NY
Current Status: Static
Road: Union Pacific
Configuration: 4-8-8-4

Union Pacific's route across the high plaines of Wyoming, including Sherman Hill, and the Wasatch Range of Utah (part of the original transcontinental railroad),  provided significant challenges to moving heavy freight. As steam locomotive technology progressed, Union Pacific ordered larger, faster and more powerful locomotives: 2-8-8-0s in 1918, the three-cylinder 4-12-2s in 1926, then 4-6-6-4s in 1937, and ultimately a locomotive which could move freight over steep Sherman Hill unassisted and maintain a fast schedule. In 1941, Union Pacific received the first out of an eventual 25 locomotives in the 4000 class dubbed "Big Boys," the last five of which were delivered in 1944. At the time, these were the longest and among the heaviest, most powerful steam locomotives in the world.

Big Boy 4018 was in service and assigned to Wyoming's Cheyenne-Green River territory in September of 1957, having received its final repairs at the Cheyenne shops in April of 1957. By October of 1957 engine 4018 was stored serviceable at Green River. 1958 saw several 4000s in service on the Cheyenne-Laramie segment only. As a result some 4000s were stored at Laramie at the end of 1958, and the last six 4000s located at Cheyenne were placed into service for just 15 days in 1959. Union Pacific 4018 was officially retired in 1962 and donated in 1964, traveling from Wyoming to Kansas City, then south via the Santa Fe into Dallas. In 1998 the museum was approached with a proposal to restore 4018 to operation for a feature film which did not materialize. Union Pacific 4018 remains on static display at the museum site in Dallas as it has been since 1964. There are no plans for an operational restoration.
