The National Transportation Safety Board today released the following update on its investigation into the September 12, 2008 collision between a Metrolink commuter train and a Union Pacific freight train in Chatsworth, California.
NTSB investigators asked for records of the Metrolink engineer's cell phone calls and text messages from the service provider. The Board today received some of those records, which indicate that the engineer had sent and received text messages on the day of the accident, including some while he was on duty.
The Safety Board will correlate those records with other investigative information to determine as precisely as possible the exact times of those messages in relation to the engineer's operation of his train.
The Board will provide further information on the progress of its investigation as it becomes available.
