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.
We know you missed seeing our steam locomotives last year nearly as much as the UP Steam Team missed operating No. 844 and Big Boy No. 4014. We have great news, the Steam Team is busy planning an excursion for No. 4014, likely kicking off August.
Union Pacific's historic steam locomotives – Big Boy No. 4014 and the Living Legend No. 844 – toured the Union Pacific system throughout 2019 to commemorate the transcontinental railroad's 150th anniversary.
The Big Boy's return to the rails is the product of more than two years of meticulous restoration work by the Union Pacific Steam Team. No. 4014 is the world's only operating Big Boy locomotive.
