A new radio communications system called Communications-based train control (CBTC), will improve the Montreal Metro’s blue line.
How does it work? Frequencies will radiate between cars to improve on providing their exact location.
Already used in other train systems around the world, this will help determine the train’s distance from another, speed, and more. This will ultimately improve the waiting times for those who use the metro’s blue line.
The project is to be in effect as of 2028, one year prior to the blue line’s extension project.
