Big Boy a must see for Train lovers

Heard that one of the remaining biggest steam engines ever was in Cheyenne so we just had to stop and take a look. Can see why they called it "Big Boy". It was worth seeing.

Title pretty much says it all. Big Boy has a history - if you know it, then you know why the train is here. If you don't know, or don't care about the history, it's just a train engine in a park....

Stumbled on the Holliday Park in Cheyenne to have a relaxing lunch on an awesome summer afternoon and found the Big Boy Steam Engine - what a great piece of history! Holliday Park is also an awesome, well shaded and relaxing oasis with public tennis courts among other amenities - nice courts for public use but sorry I didn't snap... More

The other Bib Boy (4014) is currently being restored by Union Pacific in their Cheyenne Steam shop. It is expected to be operational by mid 2019 giving Cheyenne 25% of the remaining Big Boys!

Great thing to take kids to, especially. If they enjoy locomotives! My son loves trains and the size alone leaves him in awe!

One of only a few remaining examples of the Union Pacific Big Boy Steam locomotive, it is well worth a stop just to walk around the Big Boy and marvel at the size and power of such a machine.

Holliday Park was a cute little park with a lake, a playground and a Big Boy Steam Engine. We couldn't visit Cheyenne and not make time to appreciate the historic steam engine. "Big Boy" is the popular name for the American Locomotive Company 4000 class coal fired steam locomotives. They were manufactured between 1941 and 1944 and operated by the... More

No. 4004 was the world's largest steam locomotive, using 28 tons of fuel and 25,000 gallons of water for the trip from Cheyenne to Ogden. 25 Big Boys were built for... More

My son's has loved trains ever since he was a small boy, and now he works for the RR, so we need to stop and look at the big train, as if he were still that little boy.

I was surprised to find the Big Boy Steam Engine, An Icon of it's day.. Had just been stuck in a park, left open to all the elements. When you consider it's history. Why is it not sat outside the Wyoming State Museum ?, Preferably covered. From what we saw of Cheyenne,it is a town worth a visit. But the... More
