Editing Dead man's switch (section)

===Touch sensor===
On some vehicles, including the diesel-electric railway locomotives in Canada, and on [[Nottingham Express Transit]] vehicles, the tram's speed controller is fitted with a capacitive touch sensor to detect the driver's hand.{{citation needed|date=September 2023}} If the hand is removed for more than a short period of time, the [[track brake]]s are activated.{{citation needed|date=September 2023}} Gloves, if worn, have to be finger-less for the touch sensor to operate. A backup dead-man's switch button is provided on the side of the controller for use in the case of a failed touch sensor or if it is too cold to remove gloves.{{citation needed|date=September 2023}}
