I think that a cool "version" of the DHR's locos could be made using a Bachmann On30 0-4-0 or 0-4-2t. The adventureous basher might get an outside frame 4-4-0 or maybe an OF Forney and do some whackin' here & there. The passenger cars would need to be scratched OR look at Teebee's Shapeways offerings, one of the fine open tourist cars would be great! Of course I am thinking about 1:35n2 here. The only great expenditure of time & dinero might be all the throngs of figures that would need to be made/modified for the scenes. The DHR is just about the coolest railroad around anyway!
