Has anybody approached any of the above - dj models, dapol, paddy murphy, rapido etc.? to see if this would work in theory?
Just from my own limited experience, doing cad for the likes of a H van, or bullied open would be far easier, and if successful with an established manufacturer, would lead to further projects, like Kernow has been doing for some time. An A-class straight out of the box is delusional for a loco - a D or E class would be far more realistic. Just my tuppenceworth. R.
