Probable Cause

The National Transportation Safety Board determines that the probable cause of the July 1, 2006, collision of two Southeastern Pennsylvania Transportation Authority passenger trains near Abington, Pennsylvania, was the failure of the engineer on southbound train 1143 to comply with the wayside signals and stop the train on the main track at the Grove South Control Point. Contributing to the accident was the lack of a functioning cab signal system with automatic train control enforcement. Also contributing to the accident was a dispatcher computer alarm system that did not adequately alert the train dispatcher to the overrun signal.
