In working on the Semet-Solvay project for Yarmouth I discovered the height of the styrene handrail on the InterMountain 10K car is 3-4 scale inches too high. The S-S prototype had a height of 4-feet 2 1/16-inches from the top of the running board.
Given that the handrails were safety appliances, was this height used by AC&F based on a rule or regulation?
