I have created a custom scenario using the f125 running from Doncaster to Peterborough and the signals are staying at red and it not changing allowing me to move past them otherwise its scenario failed
Do you have any northbound AI? or any trains in the yard. The crossing point onto the southbound track is beyond the yards and any northbound trains will block you in at that platform.
[Removed - Alex: Suspicious Link] If you're using any mods or custom content in your scenario, there may be conflicts or compatibility issues. Try disabling any mods temporarily and see if the signal behavior improves. If it does, you may need to troubleshoot or update the mods you're using.
