What is the minimum radius for S scale?
Well, that depends. If using small equipment, GP-9’s, freight cars, small steam, etc., expect the minimum to be about 28″ on the mainline. If running large steam, full-length passenger equipment, etc., plan to use 42″ or more as the minimum. Naturally, industrial sidings and parts of the yard may use smaller radii. Narrow gauge equipment will negotiate even small curves. Many find 22″ a nice radius to use. If K-36 or K-37 locomotives are run, look toward using a 28″ minimum for better operation and appearance.
