What is Communications-Based Train Control (CBTC)?

Communications-Based Train Control (CBTC) is a modern signaling and control system used in rail transportation. It is a wireless communication-based system that allows for the automated control of train movements, replacing traditional trackside signaling and train control methods.

CBTC uses advanced communication technology to transmit data between the train and the wayside equipment, allowing for continuous and real-time monitoring of train location, speed, and other operational parameters. This technology enables trains to operate more efficiently and safely, with improved punctuality and shorter headways between trains.
