In my part of the UK the system is that the guard closes every door except the one he's leaning out of, typically around 5 to 10 minutes after the scheduled departure time. Someone then looms in to view at the other end of the platform upon whom the guard takes pity but inexplicably refuses to open the other doors and the passenger is compelled to run the entire length of the train to board at the guard's door.
