Signaling has been a feature of urban rail transit from the earliest days. Its function is to safely separate trains from each other. This includes both a separation between following trains and the protection of specific paths through junctions and cross-overs.
Signalling system monitors speed continuously and if the train exceeds the permitted speed, the train unit applies either emergency brake or service brake. The management of the interface between different Signalling Systems and components allows safe train operations.
