Quick update...the gentleman was found and taken to a hospital for treatment. Amtrak held the train until law enforcememt arrived to take custody of the individual. He was not set off and left alone along side of the tracks. The problem escalated when he ran when authorities arrived. He was apparently suffering from a medical problem, likely diabetic hypoglycemia that causes an altered level of conciousness. It's too bad. A candy bar or a regular soda might have prevented the whole affair.
