The Union Pacific Fleet as of January 1, 2002

Archived from the UPRR web site.


Union Pacific operated more than 6,800 locomotives, nearly one-third the total of all the locomotives on Class One railroads in the U.S. The average age of UP's freight locomotives is 14.9 years, making UP's fleet one of the newest of any major railroad.

The Union Pacific Roster
The UP roster is divided into three locomotive types: diesel freight, diesel switch and slug units, and diesel and steam excursion engines. Each type of locomotive performs a different function. Freight engines pull freight cars long distances, switch engines and slug units move cars around rail yards, and passenger engines pull cars for excursion trips.

The following tables show all of the locomotives presently owned by Union Pacific. The tables are categorized by locomotive horsepower and percentage, manufacturer and percentage, axles per unit, average age, and finally, complete lists of each kind of locomotive.
