A cab unit has a covered switch which, when activated by the driver, sends a radio signal to the EOT. Two-way digital encoding ensures that only the locomotive on the particular train is capable of activating the valve. The device is battery-powered and provides the train with the rear end red light as well. The system is a legal requirement on US railroads and was instituted over the last couple of years following cases where angle cocks between cars had been closed (in some cases maliciously), rendering those cars remote from the locomotive brakeless.
EOTs are also used to provide an indication that the brake pipe of the train is complete by sending a signal back to the driver's cab when there is a change in pressure.
