Historical Equipment and Information

I'd like to plan a train trip. Where can I find information?

For historical locomotive excursions hosted by UP, see our Special Trains - Steam section. For regularly scheduled passenger service and for more information, Please  visit  Amtrak.

My relative used to work for UP. How can I get information on them?

We do not have historical records on employees to share. We suggest you try some of the railroad historical societies, or the Railroad Retirement Board. They have general information about employee records (after 1935), and their Help line can assist with questions about family histories and genealogy. The toll-free phone number is 877-772-5772, or browse the Railroad Retirement Board website.

Where is it possible to see a Big Boy locomotive?

There are eight Big Boy locomotives still in existence around the United States. They can be found in the following cities:

  • St. Louis, Missouri
  • Dallas, Texas
  • Omaha, Nebraska
  • Denver, Colorado
  • Scranton, Pennsylvania
  • Green Bay, Wisconsin and
  • Cheyenne, Wyoming – where our last two operating steam locomotives, No. 3985 and No. 844, also may be found.

Depending on the time of year, Cheyenne would be the best site to visit, if you like trains. The roundhouse there has been restored, and as the busiest railroad in the U.S., we always have some modern equipment rolling past the roundhouse. However, the steam shop is a working mechanical shop located in an active freight rail yard - therefore the steam shop is not open to the public, and is available for tours only on a very limited basis and by appointment only.

If your primary interest is in historical equipment, you might want to check out the information in our Special Trains section. It features complete lists of both steam locomotives and diesel locomotives which have been donated, including the cities and states where they can be found.


I don't see any historical information from the CNW, MOPAC, WP or Katy; why not?

Check out the overview pages on our Heritage lines in our Special Trains section.

For the most part though, the UP museum did not receive any material from those railroads when they were merged into the Union Pacific. The museum is our primary source for historical data for the website, so if the museum doesn't have it, you won't see it here. Hopefully, more historical societies will be developing websites in the future.

I'm writing a paper. Can you send me everything you have on your current business, history and equipment?

You will find this information in our About Us section.
