Metrolink Activates Expanded Use of Automatic Train Stop Technology

Metrolink has activated Automatic Train Stop (ATS) technology at an additional 49 priority locations throughout its rail systems, expanding the number of locations of ATS inductors to 105 on Metrolink routes in Orange County, San Gabriel Valley, Antelope Valley and Ventura County. The new installations are also compatible with the Pacific Surfliner ATS-equipped Intercity trains that operate on the Metrolink system.

Metrolink received expedited approval from the Federal Railroad Administration for the expanded ATS program as another important safety measure while the commuter rail service continues to accelerate the development and deployment of Positive Train Control in Southern California.

The ATS system includes magnetic inductors placed next to the track at locations where the train is approaching a curve or speed change. The ATS system sounds an audible alarm and flashing alert on the engineer's control panel when the train passes over the inductor. The train brakes are automatically applied if the engineer doesn't push a button acknowledging the alert within approximately eight seconds.

Earlier this month, Metrolink became the first railroad system in the nation — passenger or freight — to install inward-facing video cameras in its entire locomotive fleet. Metrolink has previously instituted advanced safety initiatives with the purchase of its Crash Energy Management-equipped commuter rail passenger cars and its Sealed Corridor Program.
