Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems.

A CBTC system is a “continuous, automatic train control system utilizing high-resolution train location determination, independent of track circuits; continuous, high-capacity, bidirectional train-to-wayside data communications; and trainborne and wayside processors capable of implementing Automatic Train Protection (ATP) functions, as well ...

Mar 11, 2025 · Communications-based train control (CBTC) drastically improves the reliability of subway service. Here are details about how it works, how it benefits customers, and where we're installing it. You may think of signals as the devices that look like traffic lights on our tracks.

Jan 6, 2025 · Communications-Based Train Control (CBTC) is a modern signaling system that uses real-time communication between trains and the railway infrastructure. Unlike traditional systems that rely on fixed signals, CBTC enables trains to continuously receive information about their position, speed, and the status of the track ahead.

CBTC systems rely on continuous communication between trains and a central control system, allowing for real-time monitoring and adjustment of train movements. This precision in train control enhances safety by reducing the risk of collisions and ensuring optimal spacing between trains.

Oct 10, 2018 · In this study, we will present a definition, principles and working mechanism of CBTC system. We will also try to show the subway lines which used CBTC systems from Asia, Europe and America and...

A modern railway signaling system called “Communications-based train control (CBTC)” was introduced in the mid-1980s with the objective to achieve maximum capacity while maintaining the safety requirements.

Apr 14, 2017 · Communications-based train control (CBTC) is a moving block type railway signalling system that relies on continuous telecommunications between the train and trackside equipment for train management and control.

Jul 13, 2022 · A modern railway signaling system called “Communications-based train control (CBTC)” was introduced in the mid 1980s with the objective to achieve maximum capacity while maintaining the safety requirements. CBTC is mainly used in urban railway lines and automated people movers (APM), although it can be deployed on commuter lines. What is CBTC?

Communication-based train control (CBTC) is a signalling system that uses communication between onboard and trackside equipment for train operation and control. CBTC has been widely adopted in recent years on monorails, commuter trains, metros, and other urban railway services.
