WORLD'S BIGGEST TRAIN made out of LEGO!

Vote on LEGO IDEAS for this LEGO model to become a real set! ideas.lego.com...
I've spent more than 300 hours designing this model of the iconic Union Pacific No.4014 "Big Boy". This is the biggest steam train ever produced. It weighs more than 500 tons and has 7000 horsepower. "That's too big, it can't turn" you may say. Well, lets take a look...

[@TweetsieRailroader]

This model is incredible. Not only does it look accurate, but the fact it takes R-40 curves? That’s a feat of engineering right there. Excellent work!

[@professormetal4411]

It's able to take the curves because both sets of drivers swivel instead of just the front set of drivers like on actual big boys. It's basically a combination of a mallet articulated locomotive in appearance, and a meyer articulated locomotive in function.

[@innocenttroll0]

I’m surprised that it can run on Lego track since legos had some problems in the past making models work “cough” “cough” hogwarts express

[@steffenrosmus9177]

Looking accurate? Have you ever seen an Big Boy in real?

[@gravedigger7510]

@@steffenrosmus9177 its quite accurate ( i watch the real one from KZbin ) , and this one can be used on Lego tracks so its very good , definitely gonna in my list to buy if this thing become official Lego set

Awesome!

[@davidguest3506]

The amount of detail crammed into such a small Form... Extremely impressive. This reminds me of why I loved Legos so much, to challenge myself to make things function with the odds stacked against you in this small model. Bravo.

[@thetankcommander3838]

Nothing is more majestic than seeing a mighty leviathan of the rails take to LEGO form. Job well done! I would consider buying in a heartbeat!

[@tristanperina1557]

I’ve already supported this! Let’s get it to 10,000! Also, it looks AMAZING!

[@thedarkblackspeedy3140]

Lets get this to 10K and let the factorys go nuts because everyone wants this. I want 3 for starters. Hopefully they ad the power up too on the set. I have already a big boy but more is always stronger in numbers

[@edtoomuchfun957]

Going around that curve it reminds me of race cars letting their back wheels skid to go around a tight curve fast. Nice job!

[@Northern1225]

Note:the big boy was the biggest articulated engine but there was an engine bigger,the engine being the prr S1

[@Herno1231]

This is amazing. I voted on your previous one, and for this one as well. I hope for Lego to pick this up more than ever before. I already have how I'm going to display it figured out. Here's hoping! Keep up the good work!

[@joao.viitor_7]

Why isn’t this a set!!! We need this!

[@ianbroughton7074]

Will you do more Union Pacific models, maybe the 844? This is exactly the kind of train set we need. I'm a proud Lego ideas supporter.

[@Situation-X]

Nice job man, would it be possible for a more in depth look at the train at some point?

[@Johnc0094]

That is completely awesome

[@jonathansmith8672]

I really hope LEGO will do an Icons set on the Big Boy! 🤗🤗🤗🤗💗💗

[@WasatchWind]

Beautiful set, I'd love to see how much better it could look in an official set. : ) I generally wish we got more lego trains, more lego steam - and then some american steam. The MOCs I've seen of different american locomotives always looks wonderful, but anything more niche than 4014 I doubt could get support. Maybe someday if I have tons of cash to burn I'll finally make some nice smaller lego steam locos.

[@tybehny5722]

He did it. That mad lad actually did it.

[@glowytheglowbug]

Yes LEGO please!

[@tylertichoc7330]

YEEEEEEEEESSSSSSSSSSSS!!!!!!!! C'mon guys, we HAVE to make this a thing. This is everything Childhood me could ever dream about and it's been SO LONG since the Emerald Night was a thing. Let's make this thing a reality and a this hype train worth the wait with megatons of support! I'm voting on this right now. Thank you.

[@teenytinybricks]

Very impressive that you got it to work irl!

[@ronik24]

Nice! However, there are already a few established Big Boy MOCs out there, I would be careful with non-original content. Especially morningstrummer's Big Boy is widely known, some elements of it look quite similar.

[@Towerofterrorfan21]

This will get 10,000 votes. Lego NEEDS to approve this.

[@eligebrown8998]

Great work! Might want to straighten those curves a little. I would love to but this if it was a set. Very cool

[@Mr_Tea_Rexx]

Should invest in the aftermarket wider curves. Loco looks amazing

[@mikeym32_]

Mfw this can make typical lego track turns but the official crocodile loco can't. Fantastic build!

[@A_person473]

Fun fact: the Union Pacific "Big Boys" (as of 2024) are not the biggest in the world, neither were they ever the biggest. Yes it is the biggest operational locomotive in the world. The PRR S1 has it beat in length, and the C&O's H-8 were stronger. There are more locomotives that out beat the Big Boy, but those two are the main ones.

[@5MadMovieMakers]

Look out, Thomas!

[@alphasongmusic979]

Please LEGO! Please make this an actual set! While we're at it can we get more trains?

[@pizzaeater997]

good idea. but the only thing that triggers me is that the rear part turns too. I guess its hard to do on these thight lego curves

[@marcleslac2413]

The fact it was mentionned by up in a company newspaper, it should get the companys blessing

[@dereckdanechallonergascond1374]

This should be an official set

[@BinaryArmorOnline]

Words do not exist to express how happy this makes me. If this doesn't make it on to shelves as an official Lego set, I hope you'll sell instructions, because I will be prepared to buy.

[@Swedish_bias88]

The biggest steam engine in the world is actually the Belgium quadruplex.

[@georgemeyer8521]

The UP big boy was NOT the biggest steam engine ever produced. C&O Alleghenys had 7500 horsepower and weighted 600 tons. They only built 25 "Big Boys" and C&O built 60 "Alleghenys", and even these engines were not the "biggest".

[@leongarcia8th419]

[@frogmouth2]

Great build but it looks pretty damn big which would make it a hard sell for both consumers and lego.

Valve gear is timed wrong, eccentric cranks should be timed 90 degrees behind the connecting rod, its currently timed 90 degrees ahead. Other than that its a really nice model, the valve gear is a nice touch
