If the controller handle is released, the power is cut off and the emergency brake applied. More modern versions, referred to as a 'driver's safety device' or a 'vigilance device', often take the form of a foot operated pedal which must be reset within a given time to prevent the train being stopped automatically. Usually, an advance warning is given to allow the driver to reset. It is a matter of some pride amongst drivers that they can time the need to reset within a few seconds without causing an alarm.
