General information for future tours:

Take advantage of this rare opportunity to tour the Union Pacific Steam Shop! There were just twenty-five of the massive Big Boy steam engines ever built, and only 8 remain today. Now’s your chance to visit the Steam Shop where Big Boy # 4014 is housed. Public access to the Steam Shop is only offered a few times per year. These tours include admission to the Cheyenne Depot Museum and transport to the Steam Shop on the Cheyenne Street Railway trolleys. Ticket prices are $40 per person with a $2.50 processing fee. 

Tour begins at the Cheyenne Depot Museum - 121 W. 15th St.
