Big Boy Train

Union Pacific’s famed Big Boy No. 4014: the world’s largest steam engine, will pass through nine states, including Colorado, on its fall 2024 tour. It will make two whistle stops in Colorado, but won’t be stopping for a longer display visit here. The whistle stops will be:

• Monday, Oct. 21 from 3:45 p.m. to 4:15 p.m. at the Monroe St. Crossing in Strasburg
• Wednesday, Oct. 23 from 12:35 p.m. to 1:05 p.m. at the 10th St. Crossing in Greeley

The history of Big Boy started with 25 trains, all 132 feet long and weighed 1.2 million pounds. All are now out of service or on display, except for Big Boy No. 4014, which ran in 1941 and retired after 20 years and over a million miles.
