Metrolink unveils crash prevention system

September 10, 2012 12:00:00 AM PDT
Four years after the deadly Metrolink crash in Chatsworth, a new system is being installed that could prevent a similar disaster in the future.

Twenty-five people were killed and more than 100 were injured when the Metrolink commuter train ran a red light and collided with a freight train.

At Union Station in downtown Los Angeles on Monday, officials announced the new technology will be installed on Metrolink's locomotives by the middle of next year. Positive Train control, as the technology is called, uses GPS to determine if a train is going too fast for the existing conditions, and whether a possible collision looms ahead.

If the engineer does not respond to a warning on their display, the train will be slowed down or stopped automatically. In the case of an earthquake, the $210-million system would bring all trains in the area to a stop. Ultimately, the system will be installed on most trains nationwide.
