A day after the Chatsworth crash, Metrolink spokeswoman Denise Tyrrell said the commuter train’s engineer failed to stop at a red signal before the head-on collision with a Union Pacific freight train. KPCC’s Patricia Nazario reports live from the crash site.

 

Since then: The crash led Congress to pass the Rail Safety Improvement Act of 2008, which required Positive Train Control, a GPS-based backup system designed to stop trains when crews make errors. Federal regulators announced at the end of 2020 that the technology was in place on all required U.S. rail lines.

The Los Angeles Times remembers the 25 people killed in the Chatsworth crash.
