Pictures of my Pre-war Lionel full scale 700E NYC Hudson engine. Is it the first mass produced 3 Rail Scale engine? Scale dimensions. Lots of detail. Scale couplers. Engine and tender reasonably close coupled with a double drawbar. All wheels with flanges. Runs on 3 rail track.
What do you think? Is it 3RS and if so is it the first 3RS engine? If yes then I suggest that Joshua Lionel Cowen was the very first 3 rail O scale guy.
