Positive Train Control
Metrolink trains are now outfitted with a GPS system that will slow or halt a commuter train before it collides with another, Sen. Barbara Boxer and officials announced Friday.
The commuter train network that crisscrosses Southern California now has an advanced crash-avoidance system on all the tracks it owns.
The new technology is called Positive Train Control (PTC).
In the wake of Sunday’s deadly train derailment in New York, pressure is increasing on commuter rail systems around the country to speed up installation of a high-tech accident-prevention system.
Federal transportation officials on Monday introduced a new system designed to prevent head-on train collisions like the Metrolink disaster four years ago.
