I read apparently that Southern had been having problems with its train
doors
not opening on stations north of the Thames because these hadn't been
programmed into the database that uses GPS to know where it is! Is it just
me
or is having some GPS controlled database system being used to open the
bloody doors just a teensy bit overkill?? Do they think the driver is
too stupid to know when he's at a station and might try to open them when
he's
bowling along at 60?? Sure have some sort of interlock that prevents them
opening when the train is moving but for gods sake , was this implemented
just
to keep some technicians in work? And what happens during an emergency?

The problem is to ensure that only doors adjacent to the platform open at
stations with short platforms. There is a perceived risk with relying on the
driver's or guard's memory, though signs on short platforms on the
Salisbury - Exeter line seem to me to be an adequate aid to memory. There
does seem to be evidence that while passengers are likely to check that
there's a platform alongside before opening a slam door, they are liable to
press the button and step out into space from a sliding door train.
