If you were employed with a model train manufacturer in the 1940's or 50's, what would you have done different than the way it was made? How would you have engineered it?
I'll start, with the common Lionel UCS operating/uncoupling track. To me it would have made a lot more operational sense to make the track 12'' long instead of the standard 10''. And put the uncoupling magnet at the end of the track instead of the center. The operating rails could be 2 inches longer also. This way you could uncouple the car at the end of the track and have the sliding shoes in contact with the operating rails and have the car uncoupled from the train. Would have worked well with the milk cars and lumber unloading cars. Packed with the 12'' uncoupling track would have been a standard straight section of track 8'' long so the 2 put together would be equal to 2 standard sections of O gauge track to balance the layout.
What would you have done different in design of trains?
