"Pictures of my Pre-war Lionel full scale 700E NYC Hudson engine. Is it the first mass produced 3 Rail Scale engine? Scale dimensions and lotsa detail. Scale couplers. 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."
He definitely was one of the first if not the first. I had some very nice vintage Lionel scale 3 rail freight trucks and freight cars years ago when I was running O scale. ......DaveB
