What an amazing piece of engineering. You'll get a neck cramp looking up how massive this train is. Jaw dropping. Wished this train was still traveling across the country. I'm sure it was impressive during its time in service. Highly recommend seeing a piece of history.

If you have a love for railroading this is a short stop you must make to see this size of this beast in the nice park setting. This is one of a few Big Boys Steam Engines left and it is sad to see it not sheltered from the weather to preserve it for another 100 years. This beast was... More

Interesting to learn about the largest steam engine ever built. It's a good place for a short stop as long as the weather is nice.

I'm an aircraft mechanic so I am amazed at mechanical things. I stood in amazement at how big this thing is. Very cool to see history preserved. I think I know why you are not able to climb around on this thing but it sure would have made my day if I could have. Worth stopping and seeing if you're... More

At the Depot Museum my wife and I learned that there was a Big Boy engine located a few miles away. As a couple of amateur rail fans we decided we had to see it. Despite the poor weather, we're glad we swung through the park to see this behemoth! Since there are only 8 left in the world we're... More

Saw the engine and took a few pictures. It is just what it says, a large steam engine in a park with a bunch of signs explaining it. Nice short visit.

If you are into historic trains this is certainly a "must see". Old Number 4004 is one of only a handful of Big Boy steam locomotives still in existance. In its day it was one of the largest engines in the world, specifically designed to haul heavy loads over the mountins. In retirement it has become a pigeon perch in... More

Steam locomotive fans wouldn't miss the chance to see the "Big Boy" while in Cheyenne. If you're not a rail fan, this glorious engine from a bygone era might look like a hunk of steel sitting in a park. But for rail fans, it is a surviving example of the greatest motive force every put on the rails. It is... More

Although fenced, the train itself is huge and you really need to walk the train to appreciate the size and dimension.

Located in Holiday Park, the engine is quite a site to see. Entrance into the park is free, as is seeing the engine. It does't take much time to see the engine and take a few pics, say 15 minutes top. One cannot access the engine because its fenced off. Understandable, as human contact would only cause problems (sad to... More
