We were visiting Cheyenne WY and wanted to take our dog Nugget for a walk. We found Holiday Park which has the Big Boy steam engine thereVery nice park with a lake, tennis courts, volleyball, and a kids playground. You can walk around the lake and plenty of places for a picnic lunch.The steam engine is there and it is one of several of the largest engines ever built.One thing to mention is there is parking at the park and across the street. If you park accross the street there is a pedestrian tunnel that goes under the road to get to the park

Very well maintained Steam Engine. Dont like the fence but know its for purpose. Kids love it anyway

Very cool place to visit! Huge train on display in a park, that also has tennis courts, picnic tables, plenty of parking, sports fields, walking trails, and other things to see. Definitely stop by if you can!

An absolutely breathtaking view of such a historic site. Super clean and well maintained facilities.

Good park area. But thieves lurk around there. I had to learn to look for them the hard way.

The park has easy access parking, trimmed lawns and a lot of trees plus water and covered picnic tables! It was relaxing there. A perfect place for a picnic.

Pretty cool train and even better Park. With a great lake walk, wonderful playgrounds and even an AARP workout area. It just a great spot to hangout in Cheyenne.

Very cool to be able to see one of the eight remaining largest steam engines ever built. It is stored in a beautiful a park in Cheyenne. Theres not much you can do other than look at the fenced in train and read about the Big Boy on a board, but still definitely worth visiting if you are in the area.

The view from the outside is nice. See also 360 and YouTube

One of the coolest steam engines ever made. The size is awe-inspiring.

When it comes to old trains, 4004 is the biggest out there! And as far as static displays of Big Boys goes this one is easier to get to than the one in Omaha. Plus it isnt far from down town so not out of the way to see!

Loved it! So Cool and great park with the best grass. would be a great lunch spot

A favorite train of my sons. We were so happy to unexpectedly find this train on a quick trip to Cheyenne. Would have loved to have been able to take pics without the fence, but it was great to see it in such great condition.

Its close to home, it has alot of gazebos a super cute pond to walk the dog around and the train engine is always a gun place to visit. Oh. It also has 2 play grounds.

Easy access in the park, borrow my Dad to give you details on the locomotive design and functionality and including production history.

They say only 8 of 25 Big Boys built are still around. Heck, I saw 27 on this trip alone and I wasn’t even looking for them. I have one in my backyard. Not in my area backyard, my actual backyard. I stole it, borrowed it, Engine #4999. Logistics were a little tricky, but I was determined to make it work. Don’t tell Union Pacific, cause I’m not giving it back. Neat train display in a mediocre park. My display is better.

I love trains and this Big Boy have a lot of history! I’m so glad future generations will be able to enjoy and admire such big piece of machinery.

If you love trains then plan to add this to your bucket list along with the Cheyenne Depot Museum.

Amazing piece of history located in Cheyenne, the plaques give good background info and the locomotive is easily accessed.

The steam engine is in a park near the UP Steam shop and the Cheyenne Muesuem for trains as well. The train is near the tennis courts in side a half height fence, so you cant touch the train. Its huge as most people know. This area of Wyoming has been getting lots of rain so the grass is swampy now. There is an entrance to a parking lot on the south west side. It is surrounded by busy roads. Kids had a great time.

Awesome old steam engine on display in a city park with tennis courts, basketball courts and picnic/party areas

Big Boy in good shape at Holliday park. Great seeing one of the monsters of the steam era.

Love this train and am absolutely happy it is displayed in the park

A great part of our historical town! A excellent place to teach the next generation!

Very nice park huge train glad to see a bit of history

A very important and impressive display of locomotive history located 3 minutes from the heart of downtown Cheyenne. This huge steam locomotive cannot be described with words or pictures in terms of of its immense size and footprint. If youre into steam trains or the role they played in this part of the country, you need to go to Cheyenne and see this thing in person

Very cool piece of American iron.

Its cool maybe needs a bit of polish

Love this park all year long! Personally enjoy quiet time on a snowy winter day.

Very impressive sight. Its unfortunate that it is fenced off so you cant touch or climb on it.

My dog had fun there.

Nice train after they reconditioned it..

One of a few remaining 4-8-8-4 steam engines Union Pacific had to move freight over the mountains of the west. Its certainly seen better days but its there and mostly in one piece, although it appears to be undergoing continued restoration and upkeep. Its just off the road in Holliday Park and something to see in an important railroad town.

Holy Cow. This locomotive is Enormous

Great piece of history open and accessible to the general public.

This engine is really cool to see in person. It’s impossible to imagine the scale of this machine without being there in person. I took one star off because I think the site and engine could use some better upkeep.

I saw BIG BOY at a public park, Cheyenne, WY, circa 1973-75...display then was rather rudimentary.

Something to see, very large steam engine railroad

We love the Big Boy Steam Locomotives! Glad to check another one off our list! The playground near it is also amazing!

Nice park met with friends beautiful day

Beautiful park with history....

I didnt dislike it. It just isnt very impressive to me.

What fun seeing this iconic treasure in n Cheyenne, WY

Best thing Ive ever seen since color TV

Beautiful park! And so peaceful!

Beautiful park! Very relaxing

Love looking at old trains

I grew up visiting this train and now that theyve restored it and everything thats really cool looking

Really cool for the kids

Nice engine love to run it

Great part of UP history.

Big chungus

Big boy is looking a bit work these days,but it is still worth the visit for a train buff. This massive machine is still very impressive.

Union Pacific 4004 Big Boy is worth the visit . 8 of the 25 made are still in existence. This little part of history is well honored here. The park setting is nice and the dog possible enjoyed the situation as much as I did. It would be interesting to get a second engine on display being so near such a major section of historical rail track. Make sure you also see the station, its a beautiful building.

It is very impressive! When people say its big you dont fully realize how huge this engine truly is until you see with your eyes.

You cannot fathom the size of this monster until you actually see it. A great stop on my many travels. Be sure to take a walk around the lake

It was pretty cool to see one of the largest steam locomotives ever made close up and personal. Well worth the time to see...

Great stop after visiting the downtown museum. Its a shame they have to fence if off...visiting hours to have closer access would be ideal.

An amazing piece of Wyoming and Rail Road history. Great place to visit for both locals and tourists!

Pretty intimidating up close.

Hey, I like trains. What can I say? This is a cool place to stop and to look at, and its free, so whats not to like?

Something for everyone. Located in Holiday Park with information on the engine and place to meet and kids to play. Great place to visit.

Crossed the most epic steam locomotive off of my bucket list! The restoration is truly marvelous, looks like this could just roll off into the sunset.

Fabulous place for afternoon with the kiddo! Big fun!

It was great to see

Its nice. Clean and felt comfortable.

Very interesting piece of History if your kid loves trains definitely bring them by

The railroad has been an important part of Cheyennes history. The recently restored Big Boy is a great example of local tribute to the past and the role of the steel giants that shaped the West.

An amazing piece of history. Hard to wrap your head around the size of this and the role it played

Too many homeless people and druggies to feel comfortable letting your little ones play

Cool but it would be much better if you could get rid of the high chain link fence around it

Great train and history but the best part is the memorial to a young man who obviously came from a UPRR family. He is loved by family and all who visit

The parks in this are are really fun for the kids we really enjoyed it.

Simply amazing piece of equipment from a bygone era.

Cool to see

A very impressive piece of equipment.

Nice, clean park

My kids love trains so we had to see this while we were there. Its pretty neat. Probably not going to to go out of our way to see it again but it was cool to look at!

A must for rail fans. Recently overhauled, big boy has never looked better.

We were fortunate enough to visit during a special event when they had the gate open, so we could touch it.

Very impressive and informative! It would be nice if they would put pamphlets in the Box provided. Great tourist attraction for people like my dad who worked on those big guys.

Nice clean park. Good family fun!

It was big and impressive. I can say I seen one time

One of eight. . period. Not in known existance just built. . and what a Herculean endevour. . and to think i have accidentally bagged all but half in my travels makes me tingle with delight. . . most bang for your buck is Cheyene wyoming. One 4004 sits humble and magnificent to the elements at holiday park. . while in the hollowed steam shack of UP opperational hub behind the auto parts store is the only opperational bigboy in the world . . the 4014 is a laviathan whose black heart still gurgles with the equivelent steam power of 2 nuculeur reactors. . .and with the challenger- comprise numbe one and two largest operational engines in the whole world! @$!:&? In any language- train nuts come in the know come from all directions to the mecca of mechanical wonderment. cosidering how hard it is to find a welcome way into the nearby steamshackvwithout a friend from highscool who happens to work there, scoffing, see it everyday like he is wearing searsucker onstead of pinstripes- youor luck in the scedule search for depot days for best results comes down to production schedule and luck- the elite and mysterious dream team crew that makes the magic in tgousands if manhours per mile on the one remaining bigboy that runs, and the last challenger, all reside here in thier special batcave in chyenne as headquarters. Romour may have it, there are only five in all of UP . . A shame that these master boilermakers dont have baseball cards or tshirts out to mark the shear respect in wroght-iron-whispering they truely deserve. I. Would print them in German, Mandarin, Japanese, Spanish and Russian fullsized steam dream posters so these beautiful people get the chops they deserve. And bless union Pacific for keepiing this very expensive project on the corperate teet- the british havw come closest in ups mighty shadow- there really is something poetic and beautiful happening here most folks dont understand. . . and well holiday park has a piece if that testimony between the tennis couts and the olympic sized hourse shoe pitch

Great park for our picnic and wow what a steam engine. We love Wyoming!! Cheyenne is a great place to visit.

Recently renovated and it looks fantastic. A must see.

I mean if you like trains.

I love this park so huge

They just finished renovating Big Boy and it looks absolutely wonderful!! If you can visit it at night to because they added lights to it. The headlight has a motion sensor that turns it on. What a great thing they did to preserve a part of the history of Cheyenne.

I always take my kids to see big boy! Choo choo here comes the train!

Quiet, peaceful and attractive park.

Nice little park they redid the kids play area. Take a walk around the pond and enjoy the nice weather in Cheyenne. Sorry I don’t have pictures but it’s worth the stop

Id say that its as big as an adult steam engine. Im not sure why it doesnt have a job. Im also pretty sure that its selling drugs in that park. I wouldnt make eye contact with it if I were you.

Umm, its a steam engine.

What a rare and massive sight. My great uncle would have really appreciated seeing it. Beautiful park to stretch your legs and find a grocache.

Awesome steam locomotive and cosmetically restored well

It is a big train engine, behind a fence, so you can look at it. It has history plaques around it. Not much else to say or to be expected from a landmark in a park.

This is truly a big boy engine! Loved seeing it!

Nice new kids playground installed in August 2018.Usually pretty chill atmosphere- You do get the occasional sketchy elimant at the park,but nothing too problematic. Nice place to jog,shoot hoops or take a stroll around the lake.

I l iLearn recently that the big boy train was actually built in Fort Collins Chris is very close by only about 45 minute drive via I-25 pretty badass in my opinion I had not known that before so if I can contribute that to your knowledge then not something that youve learned as well God bless you its all about it love amen!!!
