According to the National Transportation Safety Board (NTSB), which investigated the cause of the collision, the Metrolink train ran through a red signal before entering a section of single track where the opposing freight train had been given the right of way by the train dispatcher. The NTSB faulted the Metrolink train's engineer for the collision, concluding that he was distracted by text messages he was sending while on duty.
