I seem to recall that the wait for the doors to open was due to
waiting for a GPS signal to say it was OK.

It isn't on SWT Desiros - the guard's door opens as soon as he
operates the controls. The delay is then down to the time taken for
him to check the train is correctly platformed; he then releases the
rest of the doors. AIUI GPS is only used to trigger the
announcements on SWT.

Oh really? That's appallingly slow then. Having seen a guard operate the
doors in front of it surprises me too.

SN's units do use GPS (and CSDE) so their Electrostar doors are
enabled as soon as they come to a halt.
