I sometimes see this as well. I think it happens when an AI train opens its doors on the wrong side, passengers simply step out on the side where the doors open. They are a clever bunch though; they try to get back on the platform or in a train when their path isn't blocked by other lost passengers. I've seen a whole trainload of passengers climbing back onto the platform after a AI-166 opened its doors on the wrong side.
Hi, I've found out there appears to be a rogue AI passengers spawning point at the end of platform 3 at paddington. The passengers always seem to spawn there and then start walking up the track towards the ticket gates. Mike.
Hope it gets sorted soon, Don't feel right running them over on the track as I have to keep to my schedule. Can't wait for anyone
