Ross built this MOC when he was still 12! It is 8 wide, and is the most detailed MOC diesel engine I have seen to date. The Burlington Northern decals are "O" scale (1:48) and are produced by MICROSCALE DECALS.
OK, I confess, I keep coming back here just to drool over it... I see you cut the regular chains for the small bit up front. I don't normally approve ABS torture, but I'm inclined to turn the other cheek because this is THE most detailed lego diesel in existence. No kidding.
