Do you start these services direct from the timetable menu? If so, I recommended spawning on foot to start each service as the red light phenomenon doesn't seem to be an issue this way. I tried these four services and they worked (from spawning on foot). But, I do agree, the red light issue is very frustrating nonetheless!
I’ve tried and abandoned a couple of runs on this due to red light issues. I just quit to main menu and go to the old faithful routes with no bugs.
There is one with the red light at Victoria because a AI train half pulls out the station, blocking the route. You get all the way from Brighton only hit the wall of reds. The AI train pulls out of Victoria at the same time you pull out Brighton. Not sure why its not been sorted yet!
