Yes i do know about the 20 min rule: travel time + waiting time at stations and signals. All trains are within the time limit.
After watching a few videos about cargo on YouTube, if found that the details tab in the factory info panel worked for them,but not for me,which is why i never knew what was wrong with the chain. Reinstalling the game helped fix that and now i know what’s wrong: i don’t deliver enough raw materials.
What makes matters worse,is that all the mines i’ve connected to the chain,seem to produce less and less,with some of them not working at all anymore. Could it be,that the resource demand is divided up among the connected lines and that it would be better to have fewer connected?
Honestly,cargo in this game is giving me a serious headache :/
