What is CBTC?

Communication-Based Train Control (CBTC) is a railway signaling system that relies on continuous communication between trains and a central control system. This allows for more precise train positioning and speed control, leading to increased capacity, improved safety, and reduced headways (the time between trains). CBTC systems commonly use radio communication to transmit vital information, such as train location, speed, and braking capabilities, to the central control system, which then calculates and transmits movement authorities to the trains.
