Union Pacific Steam Excursion Trains
   No other railroad in this country has retained its historical equipment and honored its past like the Union Pacific.
The preservation of its fleet speaks to the high value UP places on its heritage and its role in America's history. The
fleet itself dates back to 1912, but most of the passenger cars are closer to a half-century old - built during the
height of passenger train travel. Each car is unique and chronicles a different chapter of Union Pacific's past. For more
than a century, they've transported iconic individuals (presidents and senators, generals and soldiers, artists and
architects, singers and actors) ... people who influenced and transformed America.
   The last steam engines operated by Union Pacific represented the pinnacle of railroad steam power development in
the 1940s. Steam operations ended on Union Pacific in the late 1950s, though UP has retained two of those "modern"
steam locomotives for historic and public relations purposes.  In 2015 Union Pacific is in the process of restoring a
third steam engine - the #4014 'Big Boy', one of the largeststeam engines to operate in the western United States.

UP 4014 is a 4-8-8-4 Articulated type, Big Boy, freight steam locomotive. On July 28, 2013, it was announced that
the UP was acquiring UP 4014 from The Southern California Chapter of The Railway and Locomotive Historical Society
in Pomona, with the goal of restoring it to service. 4014 was moved from Pomona to the Union Pacific West Colton
yard on January 26, 2014 and restoration to full operating condition will begin soon. Volunteers and paid contractors
will assist the UP steam crew in the rebuild predominately at the UP Steam Shop in Cheyenne, Wyoming.

UP 844 is a 4-8-4 Northern type express passenger steam locomotive (class FEF-3). It was the last steam locomotive
built for UP and has been in continuous service since its 1944 delivery. Many people know the engine as the No.
8444, since an extra '4' was added to its number in 1962 to distinguish it from a diesel numbered in the 800 series.
It regained its rightful number in June 1989, after the diesel was retired. A mechanical failure occurred on June 24,
1999, in which the boiler tubes from the 1996 overhaul, being made of the wrong material, collapsed inside the boiler
and put the steam locomotive out of commission. The UP steam crew successfully repaired it and returned it to
service on November 10, 2004. It is the only steam locomotive to never be officially retired from a North American
Class I railroad.

UP 3985 is a 4-6-6-4 Challenger class dual-service steam locomotive. It is the largest steam locomotive still in
operation anywhere in the world. Withdrawn from service in 1962, it was stored in the UP roundhouse until 1975,
when it was moved to the employees' parking lot outside the Cheyenne, Wyoming, depot until 1981 when a team of
employee volunteers restored it to service. In 2007, it underwent repairs for service, and was back up and running in
2008 to continue its run.

UP 951, 949 and 963B are a trio of streamlined General Motors Electro-Motive Division E9 passenger locomotives
built in 1955. They are used to haul the UP business cars and for charter specials. While externally they are 1955
vintage locomotives, the original twin 1200 hp 12-cylinder 567 series engines have been replaced with single EMD
16-645E 2000 hp (1.5 MW) engines and the electrical and control equipment similarly upgraded, making them more
modern locomotives under the skin. Some refer to the units as "E38-2" units, as the internal equipment was taken
from wrecked GP38-2 locomotives. The set is made of two A units and one B unit. The B unit contains an HEP
engine-generator set for powering passenger cars. The two A units were recently modified to eliminate the nose doors
to increase safety in the event of collision.
