You’re standing in the middle of Helgen. The sky is dark, the executioner's axe is raised, and the world is about to end. Then you hear it. Not the terrifying roar of a world-eating dragon, but a shrill, cheerful steam whistle. Suddenly, Alduin drops from the sky, but he isn't a scaly beast. He’s a bright blue steam engine with a dead-eyed, smiling face.
Thomas the Tank Engine in Skyrim is basically the peak of internet absurdist humor.
If you’ve spent any time on the internet in the last decade, you’ve seen the clips. It’s the mod that turned a serious high-fantasy epic into a fever dream. But what most people get wrong is that it wasn't just a one-off joke. It actually changed how people look at modding forever. Honestly, it's the reason we now expect to see Thomas in every game from Resident Evil to Elden Ring.
The Birth of Really Useful Dragons
It all started back in 2013. A modder named Kevin Brock, known online as Trainwiz, decided that dragons were, well, boring. He teamed up with some friends (Haishao and Shippin) to create "Really Useful Dragons."
The mod didn't just swap the 3D models. That would be too easy. It replaced the dragon roars with whistle sounds and changed the fire breath into something far more confusing. Brock has said in interviews that the whole thing was spontaneous. A friend gave him some Thomas models ripped from a low-quality iPhone game and asked what he could do with them. Half an hour later, the dragon-to-train pipeline was born.
People loved it. It went viral instantly. YouTube creators like videogamedunkey helped propel it into the stratosphere. There is something fundamentally broken in the human brain that finds a smiling locomotive committing arson hilarious.

Why it actually works
- The Contrast: Skyrim is gritty, gray, and serious. Thomas is a toddler’s toy. Putting them together creates a "cognitive dissonance" that the internet thrives on.
- The Sounds: Hearing the Thomas theme song get louder as a train-dragon dives toward you is genuinely more frightening than the original game.
- The Uncanny Valley: Let's be real—Thomas has a creepy face. In the context of a dragon, that smile becomes predatory.
Mattel and the Legal Drama You Didn't Know About
You’d think a giant toy company would find this funny. They didn't. Mattel, the owners of the Thomas brand, has a history of being... let's say "protective."
Trainwiz has been pretty vocal about the pushback. He’s claimed Mattel’s lawyers have gone after him for years. Apparently, an intermediary law firm once tried to take down YouTube videos of the mod, arguing it "diminished the brand." YouTube actually defended some of these videos under parody law, which is a rare win for the little guy.
Even as recently as late 2025, Brock was still making headlines for putting Thomas into Morrowind as a direct "middle finger" to the legal threats. He’s gone on record saying he fundamentally doesn't care about corporate intimidation. He just wants to milk the joke until it dies. You've gotta respect the commitment to the bit.
How to Get Thomas in Your Game Today
If you want to experience this chaos yourself, it's still surprisingly easy. The mod is primarily hosted on the Steam Workshop and Nexus Mods.
Technical Requirements
- The Base Game: You need The Elder Scrolls V: Skyrim (either the original or Special Edition).
- Mod Manager: Using something like Mod Organizer 2 or Vortex makes life easier.
- The Files: Search for "Really Useful Dragons."
Just a heads-up: it replaces all dragons. That includes the ones in the main quest. If you're trying to have a serious emotional moment with Paarthurnax, it’s going to be very hard when he looks like a 1940s steam engine.

The Cultural Legacy of the Train Mod
Before Thomas, mods were usually about making the grass look better or adding new swords. After Thomas, the "cursed mod" became its own genre.
We saw the "Macho Man" Randy Savage dragon mod. We saw Shrek replaced with various monsters. But Thomas remains the king. It showed that the modding community didn't just want to "fix" games—they wanted to deconstruct them.
It's a reminder that gaming is supposed to be weird. Skyrim is a masterpiece, sure, but it’s a masterpiece that is objectively improved by the presence of a sentient blue train.
Actionable Next Steps
- Check your compatibility: If you use other dragon overhaul mods (like Diverse Dragons Collection), Thomas might glitch out. Pick one or the other.
- Backup your saves: While "Really Useful Dragons" is generally stable, swapping core meshes mid-playthrough can sometimes get wonky.
- Explore the "Trainwiz" catalog: Brock didn't just stop at Thomas; he's made massive, lore-friendly quest mods and even launched his own space RPG called Underspace.
If you're bored of the same old Frost Dragons and Blood Dragons, just give it a shot. It changes the entire vibe of the game from "saving the world" to "surviving a hallucination." Honestly, that’s the way Skyrim was meant to be played.
