Distance from each other at which vehicles stop before coupling. The value is inherited in the section hierarchy. This value is stored as an evaluated number in the section hierarchy - so, if you use a random expression, it will be evaluated at the point you define it, and exactly the same value will be inherited. The default value is 1/6th of the vehicle height as specified in the Stock List **''[[imgy|$IMGY]]''** parameter.
