I just came across this strange situation: built a station next to a cole mine and set up everything as usual. However the mine will not make use of the railway no matter what I do. See attached screenshot.
While this would make sense and I didn’t stop the exact times I doubt that the train was slower in this case. Besides I tried to delete the road so that the only possible way was the railway. Still it wasn’t used. And I noticed that the mine information said ‘line use: no’?!
I’ve just had something similar. I connected coal and ore mines to a steel works and the steelworks to a town, but when the steelworks started producing it decided that another nearby town was easier to get to than my line with one train, so it’s not using it yet.
