Probable Cause

The National Transportation Safety Board determines that the probable cause of the accident was the unauthorized use of a jumper wire that provided a false proceed signal with a mainline switch lined to Niles Yard. The use of the jumper wire was inconsistent with Amtrak procedures for using jumper wires to override signal and train control safety-critical circuits. Contributing to the accident was the inadequate oversight by Amtrak management to ensure proper jumper wire safeguards were employed.
