What Is the Big Boy Train?
The Big Boy is one of the largest and most powerful steam locomotives ever built. Designed by the American Locomotive Company (ALCO), the engines were constructed between 1941 and 1944 for Union Pacific Railroad.
Originally, these massive locomotives hauled heavy freight trains across the challenging mountain grades of the American West, especially through the Wasatch Mountains between Utah and Wyoming.
Out of the 25 Big Boy locomotives produced, only one—No. 4014—remains operational today after an extensive restoration completed in 2019.
The Historic Big Boy Train Route
During regular freight service in the mid-20th century, the Big Boy train route primarily connected major western rail corridors.
Key portions of its historic route included:
- Cheyenne, Wyoming
- Laramie, Wyoming
- Rawlins, Wyoming
- Green River, Wyoming
- Ogden, Utah
- Echo Canyon
- Wasatch Mountains
These routes featured steep grades and long distances that demanded exceptional pulling power, making the Big Boy the ideal locomotive for the job.
