The technology works by having the state of a track mounted "shoe" read by a receiver mounted to a [[bogie|truck]] on the leading locomotive or car. In the standard implementation the shoe is mounted to the [[railroad ties|ties]] a few inches outside the right hand running rail, although in theory the shoe could be mounted anywhere on the ties.<ref name="look at" /> The system is binary with the shoe presenting either an "on" or "off" state to the receiver. In order to be [[failsafe]] when the shoe is energized it presents an "off" state to the receiver, while the non-energized state presents an "on" state which triggers an action. This allows things like permanent speed restrictions or other hazards to be protected by non-active devices.
