The serious nature of Hudson's medical condition...raises a strong possibility that it was a factor contributing to the collision of February 8...The Commission therefore concludes that engineer Hudson's medical condition possibly contributed to his failure to control Train 413. The Commission also concludes that there are serious deficiencies in the manner in which CN monitored and reacted to that condition. The Commission finds that both the policies and procedures that permitted a man in Hudson's medical state to be responsible for the operation of a freight train on the CN main line to be unacceptable.
