I wanted to test a thing when i get back on the game: Trucks cannot get loads from train stations, but can’t you group a train station and a truck stop? Like a joint hub, like with passengers (who take a train from one to another city, then move around the city with buses)
Or if you can’t, cannot you put a truck stop just a couple of spaces from a train stop, and let the AI do the handling between the station and the stop? Like a manual lay-over from the station to a truck stop across the street.
Will try it, lets see what happens.
