I drove the 1M03 1746 Brighton to London Victoria Gatwick Express service, and got stuck at a red signal between Balham and Wandsworth Common. There was a traffic jam, with trains in every signal block from there to Victoria, because a service to Seaford & Ore had stopped in the middle of the junction.
Ditto here. I guess it doesn't pay to be ahead of schedule! In the London to Brighton run, I got to Brighton a few minutes early and had to wait for the red to change, but it did after about 3 minutes. As I type this, the clock shows 18:52:00, and we were due in at 18:43:00, and the map shows 12 stopped trains ahead of me, plus 1 train blocking the switch points leading into the station. DTG, please remove a couple of these AI trains from the scenario!
