Denver Post Cheyenne Frontier Days Special
Union Pacific Railroad's legendary steam locomotive No. 844, along with one of the largest and most powerful diesel-electric locomotives ever built - Centennial No. 6936 - will pull a special train for Denver Post Cheyenne Frontier Days Special, as well as a fundraising special for the Cheyenne Depot Museum, between Cheyenne, Wyo., and Denver, Colo. The excursions will celebrate railroad history and the heritage of Union Pacific.
