Sorry for tagging onto this but I don't see Mr Boltar's posts anymore (as
it helps my blood pressure!) but he's wrong.

A PEA activation applies emergency brakes. There is an override, but the
brakes do apply in the first instance.

Does it apply the emergency brakes only when a train is still in the station
or between stations as well? I'm surprised to hear that a PEA activation can
cause a train to go into emergency as I thought TfL had elminiated this
because it is much more difficult to actually get to or from the train if
between stations.

I recall a few years ago on the Northern Line that a PEA was activated. The
driver acknowledged that the activation and said that it would be
investigated at the next station, and the emergency brakes did not apply.
IIRC, the driver also did not open the doors until he had walked down and
found out what happened.

BTW, can drivers on 92 and 96 stock use their CCTV to see what is happening
inside the coaches? Will a PEA activate this feature?
