Union Pacific Big Boy

Union Pacific’s iconic steam locomotive Big Boy No. 4014 is concluding its “Great Race Across the Southwest” tour in Cheyenne, which provided rail fans an opportunity to interact with this rolling piece of history during its tour across the Southwest.

Local railfans can observe the giant steam locomotive and train consist from popular viewing areas, such as the railroad overpass downtown, the Historic Depot, and along Lincolnway. As always, exercise caution in parking and do not enter railroad property or rights of way.

The Big Boy is expected to arrive and be active in the yards on Tuesday, November 26 at approximately 3:15 p.m, for its arrivalat the Union Pacific Steam Shop in Cheyenne. The scheduling of the return was set so that train crews could be home with their families for the Thanksgiving holiday.

Twenty-five Big Boys were built exclusively for Union Pacific, the first of which was delivered in 1941 to handle the steep terrain between Cheyenne, Wyoming, and Ogden, Utah. Of the eight still in existence, No. 4014 is the world’s only operating Big Boy and the only one still owned by Union Pacific. Following more than two and a half years of restoration, No. 4014 recently completed a tour of the upper Midwest and a trip to Ogden in May for Union Pacific’s 150th anniversary of the transcontinental railroad’s completion. The Big Boy and historic steam locomotive Living Legend No. 844 met nose-to-nose, recreating the iconic image taken May 10, 1869, when the last spike was tapped into place at Promontory Summit, creating America’s first transcontinental railroad.
