If only the trains worked like Factorio, better even with LTN.
For those that havent palyed factorio with LTN, trains in default state wait at a depot. When there is a matching provider and demanding station, a train gets dispatched to fulfill the request. After gaving done so, the train returns to the depot.
You cannot do this in Satisfactory, not even modded, because of (afaik) the different way how trains are being ‘driven’ (pathing) in Satisfactory vs Factorio.
