    What do you find out when you google "what is a vigilence control device"?
    Do you know what a "dead man's switch" is?

    One of the best known examples is the ' Dead Man's Handle ' as used traditionally on many Diesel and Electric trains .

    Driver has to keep a handle or treadle depressed whilst driving . If driver releases pressure then first a warning siren sounds , then a partial brake application is automatically made and then a full brake application if driver does not respond .

    Many variants . There is normally a procedure which allows driver to release handle/ treadle briefly without triggering the alarm and braking so as to be able to do necessary tasks away from the driving position .

    That is the traditional system . Modern trains have much more complex integrated safety systems .

    You were already given a good starting point: "What do you find out when you google "what is a vigilence control device"?"

    We can't do your work for you - you've posted question after question after question without having put in the tiniest piece of effort. This helps neither you nor us.
