I read about this earlier on this group.

If a driver dies in the cab and releases the dead man's handle, the line
controller will at first try to contact him to see why he hasn't reset and
continued on his way (It does happen that hands occasionally just slip off
the controller.).

If that is unsuccessful the line controller will then link into the train's
PA and request that any LUL employee on board come forward and see what's
happened.

Failing that, IIRC, they might send somebody down to see what's wrong.

No it's not. If you had a dead man's handle on the Vic and the driver had
a heart attack, the train would stop in the tunnel with nobody on board
able to radio for assistance or talk to the passengers. Without a dead
man's handle, the ATO would drive the train *safely* to the next station
where the driver and passengers could more easily and quickly be attended
to. Which would you prefer?
