Deadman while in stations

Yes

Just to add... If the driver of an 'A' stock wants to release the deadman, he must place the reverser in the 'Off' position before letting go of the controller.

Most of the time you do, sometimes you dont, depends how you feel!

No deadman in ATO. The cab doors are on an interlock so the train will not start with the doors open, nobody will jump out.

And if that brake don't work in an emergency, you've always got the 'RLF' brake!

Off & Release is coasting.



That Alarm you hear is the OPO Alarm, I can't remember its exact use but I know it's only installed on Tube Stock, on the 73TS to acknowledge the alarm you can either hold the CTBC back down or press the 'Brake Test Enable and Radio Alarm Reset' button on the offside part of the cab.

Brake Release & Motor off

Is a better explanation


The purpose of the OPO alarm is to notify the line controller that a driver may have become unconscious, or have a similar problem. On sub surface trains, generally a driver on a train going in the opposite direction can check the condition of a colleague, hence the alarm is not required. In a single track tunnel, it's not possible to approach a train and check the condition of a driver, which is why only 'tube' trains have them fitted. The alarm will alert the line controller, who is then able to communicate with the passengers by using the trains PA system.

Its so that if the river was to pass out / die etc etc the alarm would go off, not be reset and then an alarm goes off at the Line Controllers desk which tells him there is a problem. They can then make a PA to the train to ask for a member of staff, or at least thats the idea! Its really there to stop trains being stuck in tunnels.



To do that, the TBC has to be in service one position, otherwise it will not work.
