I’m not sure if this is a bug or not so though I would put this here rather than the technical forum to see if anybody has any ideas. I’m running on Xbox One X. I’ve set up a couple of scenarios, just to try out the route before running services. The first one was Lichfield - Redditch using the 323. I found that I was getting several yellow lights south of Birmingham followed by a red at Barnt Green, which cleared as I approached it. Maybe something to do with the junction? The second was Bromsgrove to Lichfield, using an HST with one stop at Birmingham NS. I had some yellow lights north of Bourneville and a red, which cleared as I approached it. Interestingly though, there was no red light at BNS. Then I Spadded a red light at Aston, which I hadn’t noticed. In neither case were there other trains ahead of me. In the first scenario, mine was the only train. On the second, I set up a couple of AI trains in the opposite direction but had passed both of these before the first yellow. So why the yellows and reds?
