The idea of this concept is to have different people (or groups thereof) manage different parts of the map with focus on different goods. These parts are connected via a transfer terminal with the ML where they exchange goods and are brought to their final destination. It requires some kind of role-playing, some general manager to plan the ML layout and co-ordinate. Very well playable also with a track sharing patch.

This is untested yet but goes in the direction of wwottdgd.
