Union Pacific has released a detailed schedule for “Big Boy” 4014’s upcoming tour across Wyoming, Utah, Nevada, California and Idaho in July, including a public excursion over the legendary Donner Pass. The month-long trip is supposed to be the first of at least two outings this year that will take the world’s largest operating steam locomotive to multiple parts of the UP system. 

During the tour, the Union Pacific Museum will host a special passenger excursion behind the locomotive on July 14, from Roseville, Calif. to Sparks, Nev., on the former Southern Pacific route over Donner Pass. More information and ticket information will be posted at www.UPtraintix.org in the coming weeks. 

The locomotive is expected to run again in the fall, venturing to Texas, Arkansas, Kansas, and Illinois, among other states.
