Can someone tell me what the correct prototypical height from the rails is for modern box cars, refers, etc?
I’m converting my USA Trains “Ultimate” cars (1:29) over to Kadee #1 couplers and discovered:
1- a 0.188" shim is required, even though Kadee claims only a 0.075" shim is needed on thier web site.
2- once the conversion is done, neither the straight or the droped coupler lift bar will fit and a new lift bar must be fabricated.
All this has left me wondering if the USA Trains cars need to be lowered like the Aristo cars.
Thanks,
Mark
