Union Pacific Steam

No other railroad in this country has retained its historical equipment and honored its past like Union Pacific. The preservation of its fleet speaks to the high value Union Pacific places on its heritage and its role in America's history.

One of the largest steam locomotives ever built, UP No. 4014, was acquired in 2013 and towed from California back to Cheyenne. Check out the video gallery for all the No. 4014 Project film clips, and Community Ties for archived updates. Now in 2015, UP is dedicating even more resources to its Heritage Fleet Program. Watch our UP Steam Updates to see the latest.

Stay tuned to Facebook and Twitter for updates on all Steam .
