I made a double track line with standard crossing and proper signals. I had old mechanic signals and I electrified my line. Then when the train reached the other side of the line, it says “Waiting for free path”, even there’s only one train using the line.
It’s not a missing electified part as if I remove electricity on the line, it says just “no path”. It just wait for something to come and I can’t find what.
Are your signals all set up correctly? One-way signals can sometimes block a train from going where it needs to go, even if there is only one train on it.
