me too.
yesterday. added more trains to increase frequency. nothing happened. Added roads all around the forest and the saw mill try to get the saw mill and forest “hooked in” again. nothing. Added roads between forest -> saw mill -> town ….. nothing.
I think I have figured out something though. There has to be a need for the goods you produce. Say you set up line “A” with horse drawn transport. You add vehicles until the production stops increasing. Then you build some roads to connect more resources and set up line “B”. But …..
If the goods from line B go to the same city as line A you should see production in line A industry go down. So it seems that the city is choking on goods. Demand driven. City “ok to recieve goods”, saw mill “ok to send goods therefore ok to recieve wood”, forest “ok then I produce and send wood”.
So I started a new map. and started a train line immediately Forest -> Saw Mill -> Town. And to be sure I did not “kill the spawn point” for goods I only upgraded the road and deleted the rest. added train station and connected to the road.
No production started. And I did this test so that the goods that were to be produced did not have to compete with another source.
So I added a road again between forest, saw mill, town, and now goods started to be produced. So I added horse drawn transport and the goods started to use that “Line use YES”. Then I added more trains to improve frequency. And then I deleted the horse route and ended up with “Line use NO”.
Seemed the train route was invisible to the game.
I keep running into so many problems with this game I will never be able to complete a map…. 🙁
