I been model rail enthusiast for near on 50 years, and this question has only just popped up, at which point on 00 gauge set track work, is the dimension for the radius taken? is it taken from 1) the outer rail, 2) middle of both rails, or 3) the inner rail? or is it some other point on the track, i expect theres lots of you who are thinking thats an easy one to answer, but i just dont know.
