The Big Boy is the largest articulated steam engine ever to grace the prairies, although heavy the Big Boy could go 80 MPH without hauling anything. Some might speculate that the Alleghany is the heaviest, although some facts are not what they seem. Nothing like Big Boy has ever been seen, only 8 remains in existance.

Unbelievable! That's the best 3-D-model of the 4-8-8-4 I've ever seen! Wonderful weathering! With all this glass stuff it looks like jumping out of steampunk or 1900's world exhibition.
I'm going to model a UP-class 4000 too, but I bang my head. No chance without detailed faksimile plans...
Do you use some UP-or ALCo-plans?
