What is Communications-based train control?
'''Communications-based train control''' ('''CBTC''') is a [[railway signal]]ing system that makes use of [[telecommunications]] between the [[train]] and track equipment. By means of a CBTC system, the exact position of a train is known more accurately than with the traditional signaling systems. This results in a more efficient and safe way to manage trains. Metros (and other railway systems) are able to run more frequent trains while maintaining or even improving safety.[[Join Now]] {{Tech-stub}} [[Category:Rail technologies]]
