Oh dear. So the procedure at *every* stop is:

- Guard opens own set of doors
- Guard step out onto platform and checks train is correctly
platformed
- Guard opens remaining doors
- After passengers have finished boarding/alighting, guard closes all
but own set of doors
- Guard checks everything is OK
- Guard steps (or squeezes) onto train
- Guard closes own set of doors.

Surely it's easy enough for the guard to travel in the rear cab,
allowing them to lean out of the window and open/close all doors at
once?

Is that very much different than the traditional, guard opens (inwards)
van door as train enters platform; Guard steps onto platform and watches
passengers boarding/alighting; Guard either blows whistle and holds up
green flag then re-enters train or re-enters train and while leaning out
of door presses bell twice; Guard continues leaning out of door
observing departure until the train leaves the platform, pressing bell
or applying brake in case of problems; Guard closes van door.
