    Schuco rail length calc

    Chaps, I notice the Schuco Rail length calculation is "22 mm + [number of modules x (module width + 21 mm)]". I'm guessing this leaves zero gap at the end of the rail after the end-clamps. Are Schuco expecting their end-clamps to be flush with the end of the rail then?
