The biggest steam engine in the world – the Big Boy – was allready build by serveral LEGO fans. But none of them used the old spoked wheels for the drive wheels and the large 1/4-panels to model the boiler. My Big Boy should fit in with my other 8-wide train models. First a stand alone model was planed, I didn't thought about going through curves with a 4-8-8-4 [2' D, D 2'] wheel arrangement. The tender in addition has got 7 axles close together.
Due to several request I've recieved by email and as feedback: There are no building instructions nor a part list for the Big Boy LEGO model available.
Is it possible to turn standard Lego driving wheels into 9-volt wheels?

The fact that people have been raving about this model for 6 years really shows how good it is. There is nothing more one can say. Du hast echt unglaubliche Arbeit geleistet!!! It would be great if you could tell me what you think of my BR50.
Cool the big boy is my favorite train nice job (P.S I hate to tell the person who said the yellowstone is the largest hate to tell you this but the yellow stone isn't the biggest train the big boy still is the big boy is a 4-8-8-4 and the yellowstone is a 2-8-8-4 this difference makes their size different and also I've seen the model trains of them and in every scale and the big boy is always the largest of them)

This is awesome, I remember seeing the big boy in Green Bay, and this looks eactly like it! Excellent work! ~T
AWSOME, but not technicaly the biggest Stema Engine ever built. Yes it is known as that, but the Duluth, Messabi, & Iron Range had a 2-8-8-4 that had a larger boiler, 4 feet more face plate to face plate lenght & more tractive effort then a Big Boy... ;-)
But still this is a great model of the Big Boy!!
