Green Line Train Protection System

The Green Line Train Protection System (GLTPS) is a train monitoring system that will help operators reduce the risk of train-to-train collisions by scanning the track for other vehicles, monitoring train speed, and stopping the train if it’s approaching a signal or obstacle too quickly.

Contract awarded: Notice to Proceed given January 2020
Projected completion: 2024
Budget: $170,228,620
Status: Design Development

GLTPS: Benefits and How it Works

GLTPS works through sensors along the tracks that transmit data to the train as it approaches. Using onboard alerts and communications, the system notifies the operator or automatically stops the train when another vehicle is detected or when speed restrictions are necessary. These upgrades will help improve safety and reliability on the Green Line.
