Hi DTG Alex DTG Matt I’ve run the 1h10 timetable service on the Brighton mainline after separating the train at haywards heath and proceeding towards final destination of Preston park I get stopped at a red light. On signal gantry with t417 on left signal and t423r on right about 1.0 miles north of Preston park station. On looking at the route map it shows a grid lock of services held at red lights all the way into Brighton. The signal should be passed at around 0815 to get into Preston park for 0817 arrival time I have sat at the red light for almost 20 mins and nothing happens. I think the service may result in a gridlock and inability to complete. I am playing on the latest version of tsw4 on ps5 with the recent may update installed. Wanted to flag as fault but wasn’t sure where to do it. there seems to be 2 12-coach trains either side of a red signal coming out of Brighton platform 3
