Full length passenger cars are usually 85' over the couplers. Shortie cars could be 72'. Probably 80% of the full length and must negotiate 20" radius HiRail track with ease.
As for the general operating radius of Scale S Gauges, I don't know that answer. Need some feedback for that. Feel free to chime in.

Usually take 75% of an O gauge measurement. That's close to what is possible in S. But a radius is a radius. So if an O gauge car can do a 20" radius, so can an S gauge car which is shorter so the trucks don't have to deflect as much. At least that's how I see it. I've been driving for the past 8 hours, so forgive me if I'm wrong.
