>>7916521Lego locomotives are kinda my thing, as well as the space thing from Halloween. (I have plans for that, BTW), so I'll redesign the engine. I want to lengthen it anyway, so I'll likely put a small motor in the boiler somewhere, and gear it low. Lego trains tend to move too fast anyway. Battery box with either go in the redesigned tender, which will have the correct 6 wheels, or I'll put it in a brake coach to hide the cabling. Not sure what I'm dong about the motion yet.
