PS5 Red Signal Great Western Express Christmas Closures

Good morning everyone

I've just got a red signal at Great Western Express in the "Christmas closures" scenario, which probably won't turn green anymore.

Has anyone there had a similar experience?

I turned the train around just before Paddington and then passed it on the way back to Slough.

And when I look at the map in front of me, I don't think anything else is happening.

 

I just ran it on PC Steam, and didn't get the red signal. Was able to complete the scenario.

I don't have the Diesel Legends of the Great Western DLC, do you?

 

In a second attempt it worked for me, I have no idea what was wrong with the first attempt. Thanks
