As far as I'm aware, this passenger emergency handle operation is now
the same principle on all stock.

On 73 stock, the Round The Train is lost so an emergency brake
application is made. We do have a button on the floor to allow this to
be overridden though, but it has to be kept pressed for the duration -
and the Sonalert still sounds all the time the handle is down.

The button on the floor is an addition since I was on the Picc Line. I
can't remember what the procedure was then. I know the alarm came up on
the TEP and I suspect that you could release the brakes by cutting out the
RTC, although of course the alarm would still remain. Or it may be
that the car could be by-passed via the TEP. They still had Guards on the
trains then (1978), so any problems were left for the Guard to sort out
:-)

On the 95 stock, the RTC is only lost if the alarm is operated during the
16(?) seconds timer when departing the station. At all other times, there
is just a warning in the cab that can be cancelled. The talk-back
procedure would then be followed.
