Lesson plan
Continuous Automatic Warning System
The Continuous Automatic Warning System (CAWS) is a form of cab signalling and train protection system used in Ireland to help train drivers observe and obey lineside signals. CAWS has been in use on Iarnród Éireann diesel trains since 1984. All NIR trains operating cross-border must also be fitted with CAWS. Coded track circuits, which form the basis of the system (see below), are installed on all Dublin Suburban and Intercity routes to Cork, Limerick, and Athlone and as far as the border on the Belfast line. This system is of American origin, being originally supplied by US&S, then a division of Westinghouse Air Brake Company (WABCO). Current equipment is supplied by SASIB, a division of Alstom.
