The system also has a problem at smaller two platform stations if one
platform is shorter than the other. *There was a case where the london
bound platform could take 12 coaches but the country one only 8. *As
the GPS was not sensitive enough to tell which platform the train was
at it would only open 8 coaches in both directions.

Just to clarify a couple of points. On Electrostar the guard does not
release the doors, the driver does it. The Victoria release takes a
while because the train does not receive the GPS signal owing to the
Victoria Place complex. For this reason when we attempt the door
release the train computer asks us where it is in order to know how
many doors to open.

Also note there is no facility to prevent wrong side door releases. t
