This is a bug i found in Run 8 that is still there even after update 5. https://www.youtube.com/watch?v=nbo8KBRSA_Y It shows how an AI train will stop at Gomez junction even though the signal was clear. As soon as the train passes the signal,the signal drops to red.Then the train also stops and then locks the junction after a few seconds as it is now occupying that track area.
I put this post here as no thread for the latest patch 5 bugs. You can move it to another thread if it is in the wrong place.
