What Travellers Say
Reviews Summary
Visitors consistently praise Big Boy 4004 as an awe-inspiring piece of engineering history, with many recommending it as a must-see stop in Cheyenne. Its impressive size and static display in a pleasant park setting are frequently highlighted as major positives.
"If you're reading this, you probably already know what the big boy is. For anyone new, this is one of the world's largest steam engines. It was used to transport large amounts of freight across the plains and deep into the Rockies.
With only a few made, this was one of the candidates to be restored as part of the Union Pacific steam program. It was not picked and has a great display in a city park. If you are in town or even passing by, stop and see one of these amazing feet of engineering before they had computers."
