I have done a system control for my train. It help train to go on load station only when they are called. That mean more efficient work, an less train on the rail blocking others.
A document explain it (in french), so i put it here and if you need some translation of some part i can help you.
In this document i explain 3 differents things :
Part 2) best load station
Part 3) best unload station
Part 4) control system
I have build all my systeme with plan to get the more efficient railway, so let's see how it work
