On September 12, 2008, a passenger train and freight train collided head-on in the Chatsworth district of Los Angeles, CA. Each train was initially travelling at more than 40 mph.

With assistance from emergency responders, local authorities, and accident survivors, both the U.S. Department of Transportation’s Rail Accident Forensic Team and the National Transportation Safety Board investigated the accident. This report on the Chatsworth accident by the Forensic Team presents the estimated sequence of events of the collision, the behavior (dynamics) and specific structures of the trains, passenger injuries, the performance of emergency preparedness and crashworthiness features, and recommendations for enhanced protections to improve passenger safety in the future. The appendices include greater technical detail on the train structures and dynamics, and passenger experiences.
