This is a bit of a rant but never mind, just need to get it off my chest. If you close and lock the doors of a train a minute or more before its timetabled departure, then the timetable is wrong, simple as that. I understand the need to get trains away punctually but the point at which I can no longer board the train (or get off it, I suppose) is the point that it has for all practical measures departed. It doesn’t matter if it’s then sat in the station for a minute—I can’t get on, it makes no difference if it’s in the station, down the line or on a different planet. If the timetables don’t work unless this is done they obviously need adjusting. Stop lying to people.
