The National Transportation Safety Board (NTSB) announced that it completed its investigation into the fatal September 12, 2008, collision between a passenger commuter train and freight train in Chatsworth, California.  In its synopsis of findings and recommendations, the NTSB recommended that inward- and outward-facing cameras and audio recorders be installed in all controlling locomotive cabs and cab car operating compartments in order to verify that train crew actions are in accordance with safety rules and procedures.  The NTSB recommended that such devices have a minimum 12-hour continuous recording capability, that the recordings be easily accessible for review, and that railroads regularly review such recordings in conjunction with other performance data.
