During World War II Union Pacific operated some of the most modern and powerful steam locomotives ever built. Among them were the famous "Big Boys," the largest steam locomotives in the world. Working with them were the "800-class" high-speed passenger locomotives, as well as hundreds of older class steam engines. Union Pacific's steam legacy continues today with the preservation and operation of its historic fleet – No. 844 and No. 4014.
