Los Angeles Metrolink — a 512-mile commuter rail system, which serves the Southern California counties of Los Angeles, Orange, Riverside, San Bernadino and Ventura — is moving to be the first railroad to install and implement a positive train control (PTC) system.
PTC is collision avoidance technology that monitors and controls train movements remotely, can prevent train-to-train collisions, prevent unauthorized train movement into a work zone, halt movement of a train through a switch left in the wrong position, and stop trains exceeding authorized speeds.
Congress has mandated that freight and passenger railroads install PTC on designated lines by Dec. 31, 2015.
