signalling systems The TVM system is used only on high-speed lines and in the Channel Tunnel. Outside of the high-speed lines, other signalling systems are used. Every TGV train is equipped with the KVB (, "Beacon Speed Control") which is used throughout the French network. In addition to TVM, the following systems are used in various combinations: KVB, the French signalling system (electro-mechanical with radio beacons) ATB, the Dutch signalling system (induction based) ATB-NG a newer version of ATB (beacon based) ATC the Japanese signalling system (induction based) Blocco Automatico a Correnti Codificate, the Italian induction-based protection system used on some lines with speed limits above 200 km/hr. MEMOR, the Belgian signalling system (electro-mechanical) TBL, a newer version of MEMOR (electro-mechanical with radio beacons) InduSi/PZB the German signalling system (induction based) LZB, the German system for high-speed lines (also induction based) AWS, the British signalling system (induction based) TPWS, the warning system which supplements AWS ETCS, the European Train Control System is a signalling and control system designed to replace the 14 incompatible safety systems currently used by European railways, especially on high-speed lines. Integra-Signum the Swiss induction based signalling system. CAWS, a similar form of in-cab signalling system used in Ireland.
