Brief on Communication-Based Train Control (CBTC) Systems

Vandana, Vipin Chandra Dobhal

Abstract: A communication-based train control (CBTC) system Communications-based train control (CBTC) is a railway signalling system that makes use of the telecommunications between the train and track equipment for the traffic management and infrastructure control. By means of the CBTC systems, the exact position of a train is known more accurately than with the traditional signalling systems. This results in a more efficient and safe way to manage the railway traffic. Metros (and other railway systems) are able to improve headways while maintaining or even improving safety. In this paper a brief overview of various components of CBTC and their interfaces have been proposed in detail.
