Big Boy Steam Engine 4004
Table of Contents
Description
Let’s talk about the Big Boy Steam Engine 4004—a serious heavyweight (literally and figuratively) in the world of American rail history. When you roll up and lay your eyes on this jaw-dropping mechanical marvel, sitting stoic just off Morrie Ave in Cheyenne, you can’t help but channel your inner kid. Honestly, I don’t care if you’re a hard-nosed train aficionado or you struggle to tell a caboose from a coal car—this engine triggers a mix of awe and nostalgia that’s hard to shake off.
Now, I won’t sugarcoat it—it’s just one locomotive, parked immobile, outdoors. But wow, what a locomotive! Union Pacific’s Big Boy engines are legends for a reason. Only 25 of these bad boys were ever built, and the 4004 is one of just eight left on Earth. The sheer size gets me every time; it’s practically bursting out of its display fence. You’ll notice families, retired engineers, and camera-toting tourists hanging around, and just about everyone ends up muttering “I had no idea these things were this big.”
Don’t expect gates, ticket lines, or gift shops. This is a straightforward, no-frills, honest-to-goodness slice of railroading history. It sits in Holliday Park, which—by the way—makes the visit super easy for everyone. There are ramps and paved lots, restrooms that aren’t scary (phew), and parents will appreciate that the spot is pretty kid-friendly. Most folks spend 20–45 minutes here, maybe a bit more if you’re the type to circle the engine three times for “better angles” (guilty as charged).
The best bit: even if you’re on a tight travel schedule, you can swing by, soak in the magnitude, and snap some killer photos without fuss. If you’ve ever wanted to brush up against an American legend, this is your chance.
Key Features
- Massive Historic Locomotive: Measuring more than 132 feet long, Big Boy 4004 is among the largest steam locomotives ever built—an absolute beast in person.
- Outdoor Display: Set in an open-air environment, you can walk right up to the engine for close views and photos. No ropes keeping you at arm’s length (though climbing isn’t allowed—I did check, alas).
- Wheelchair Accessible: Paved paths, ramps, and accessible parking make it easy for everyone to get close, including those with mobility needs.
- Family Friendly: Space to roam, safe footing, and even a grassy park area nearby so kids can burn off some steam (pun intended!).
- Onsite Amenities: Located within a city park with modern restroom facilities—no hunting for a coffee shop just to wash up.
- Unique Photo Opportunities: The sheer size and classic look make for some epic selfies or family shots—I’ve seen engagement photos taken right next to the drive wheels.
- Open Year-Round: No locked gates, making it super convenient for spontaneous stops or off-schedule visits.
- Educational Plaques: Info signs scattered around help decode the technical details and history, for those who want the story behind the steel.
- Quiet, Relaxed Atmosphere: Since it’s in a public park rather than a bustling tourist museum, you can actually hear yourself think while you soak in the history.
Best Time to Visit
Alright, I’ll be straight—Wyoming’s weather is no joke. Unless your idea of fun is getting wind-whipped in sub-zero temps, I’d steer you toward late spring through early fall. From May to September, you’re in that weather sweet spot; sunny skies, green grass, and temps that make wandering outdoors feel good, not punishing. Summer brings more out-of-towners, sure, but the spot doesn’t usually feel crowded. There’s just enough space to stake out your view or plop down for a picnic without someone photo-bombing your shot.
Want the postcard-perfect lighting? I’d aim for early morning or late afternoon. Not just because I love golden hour (who doesn’t?), but the play of sunlight on the black iron and big silver drive rods… it’s dramatic in the best way. If you want the park at its quietest, try weekday stops; weekends draw more families and local events, especially during Cheyenne Frontier Days in July. Consider this your insider tip—hit it midweek, grab your coffee, and have the place nearly to yourself.
Outside of summer, the snow can add a whole mood—think Big Boy, steam-era grit, and winter’s hush. Dress for it, park close, and you’ll get a very different but equally impressive scene. (Just don’t lick the metal. Trust me, as the kid who learned that lesson on a dare—I’ll leave it at that.)
How to Get There
Not gonna lie, Cheyenne is pretty easy to navigate. If you’re driving, the area’s got ample parking—even RVs have enough room to maneuver nearby. It’s around five minutes from the city center, and honestly, if you miss it, you weren’t paying attention. Public parks, street signs, and—if you’re old school—a folded map, will get you right there. If you’re navigating with a rideshare app or coming from the interstate, it’s almost embarrassingly simple. Just punch in “Holliday Park” or “Big Boy Steam Engine” and you’re good to go. The route’s paved, signage is clear, and you don’t need to stress about rough roads or backwoods directions.
If you’re rolling in on an Amtrak or Greyhound, it’s a short cab (or even a solid walk) from the stations. I’ve bumped into plenty of tourists who just strolled over from nearby hotels; safe paths, crosswalks, and pretty scenery make it a nice leg-stretcher after a long drive.
For cyclists: you’ll find bike racks nearby, plus the ride through Cheyenne itself is honestly kind of charming, especially if the prairie breeze isn’t too grumpy that day.
Tips for Visiting
A few little nuggets I’ve picked up—mostly by learning the hard way, but hey, that’s half the fun when you travel, right?
- Bring a Camera—or phone, whatever. Photos don’t do justice to how absolutely titanic Big Boy is, but you’ll want to try anyway. Get shots from the front, standing next to the drive wheels, or throw in a family member for scale.
- Check the Weather. This is an outdoor attraction, and Cheyenne is notorious for its sudden wind gusts and unpredictable clouds. I once got caught in a squall, umbrella flip and all, but it did lead to the most dramatic sky for my pictures!
- Pack Snacks or a Picnic. Holliday Park’s grassy areas and benches make for a great snack spot, especially if you have kids in tow. There are restrooms, which earns big points if you ask me.
- Look for Events. Sometimes there are local steam shows, history walks, or school tours happening—you might catch a local expert dropping unexpected stories or old-timer railroaders sharing their memories. Don’t be shy about joining in; I once listened to a retired engineer talk about driving a Big Boy and, frankly, it gave me chills.
- Keep an Eye on Little Ones. The park is kid-friendly, but the engine itself is fenced off for a reason. It’s tempting to try and hop up for a close inspection, but safety first (plus, you don’t want a “get down from there!” moment).
- Read the Info Signs. They’re easy to skip, but the plaques have quirky facts you won’t find from a quick Google search. Did you know these engines were built to haul massive loads over the Wasatch Mountains? Makes your morning commute look pretty wimpy, if you ask me.
- Early or Late Visits. If you want golden light, cool air, or fewer crowds, show up early or closer to sunset. You’ll get a calmer atmosphere (sometimes it feels like you have a private rail yard).
- Accessibility is Solid. Don’t stress about mobility issues; there’s parking close by, smooth pavement, and access ramps that make it easy for wheelchairs and strollers alike.

Take Your Time. Most folks linger for 20–45 minutes. If you’re a true train buff and want every angle, give yourself a good hour, bring a notebook, or just hang back and watch the changing
