Thanks for the tips, guys. It did work but only for a moment… I forgat to check the city demand which already was at 50/50… Then i tried to deliver the goods from mill.2 to the new city where the coal mine belongs to. Hooked up 3 goods wagons to the coal train but then the coal wouldn’t transfer anymore to the truck stop, to be picked up by the mill.2 truck… Instead mill.1 started to upgrade its production significantly and filled up the freight station with goods which were then picked up by the coal train and taken to the new city. The coal mine production upgraded too, coal wagons now fully filled ( nice new load animation ! 😉 )
Great fun, learned a lot during this exercise ! 🙂
