San Bernardino UP Big Boy (1250)

UP steam engine #4014, known as "Big Boy." 4014 is one of 25 huge steam locomotives built for the UP in the early 1940's, for hauling freight in the Rockies. The engine has been in a railroad museum in Pomona, but UP bought it so as to restore it and use it for special occasions. These pictures were taken in the UP yard near San Bernardino. The engine is in that yard for maintenance that needs to be done before it can be moved to Cheyenne, WY where it will be overhauled. For more detail on the engine and move, and for additional pictures, see Zach's Union Pacific Big Boy
