I have a problem with the electrical train. All the line is electrified, but when the electrical train arrives to the station it say to me that there isn’t any path. I have checked the line and it’s ok.
There will be a small gap in your electrification somewhere. You need to closely inspect the entire line using the ‘electrification’ tool. Electrified track will show RED any gaps in the electrification will show GREEN, click on any green part to fix the problem!
