Hi Chuck: Well I model Pennsy, but would have loved to model the Milwaukee Road, if only there were some Milwaukee prototypes available in live steam. And I would have loved modeling the impressive electrics they used. Here is a photo of my K4 in live steam in gauge one in full flight. I chose pennsy because I like that husky no nonsense look of their steam engines, and the availability of some steamlocos and information. Easier from France. I include a photo of a Swiss friend's Hiawatha in live steam in 1/32 scale entirely scratch builtI made that photo at an exhibition we ran at in the Mulhouse museum. And lastly another big atlantic an E6 hauling the Detroit Arrow here in Ardèch, France. Happy modeling.
