I got somehow a problem:
I have a train Line 1 for the route A-B-C-B-A with some signals. If no train is assigned, I can see that the line is correct and working. After I assign a train to Line 1 it disappears and the train will drive to the next station doing nothing. When I get the train back to the depot, Line 1 will appear again. It happens with all other lines.
But: If I get all trains on the first track of the rail station it works fine (all lines will go through the first track and don’t disappear when I assign a train), but I can’t have that because of the waiting times..
Does anyone else have the same problem?
