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 can only speak for 73 stock as that's what I drive, but yes at all
times. A PEA activation breaks the Round The Train circuit thus causing
a full emergency brake activation. There is a large button on the floor
under the driver's feet that allows this circuit to be temporarily
bypassed to allow a train to be taken into a station for the matter to
be dealt with prior to resetting, but the basic principle is that the
train stops on activation of the PEA.
