As soon as the journey starts I'm asked to open the doors, but the passengers don't actually start loading, the loading graphic in the top corner doesn't actually move, been waiting 30mins now
Is it in Winter by any chance? Could be the same issue I had, sorry that should be still have. https://forums.dovetailgames.com/threads/ntp-passengers-not-boarding.18450/
Sometimes the setting in the train is messed up and they set the command for the other platform. i.e Platform is on the Left but unloads on the right. Happens on some GWE services If the unloading icon does not change I try opening the other side door usually works fine.
