Amtrak spokesman Marc Magliari said Wednesday that the incident happened between 1 a.m. and 2 a.m. Tuesday. Someone on a passing
freight train spotted the man around 8:30 a.m. Tuesday along the tracks in the Marion County town of Florence.
The man had been a passenger on Amtrak's eastbound Southwest Chief. It wasn't clear how he left the train. His name wasn't immediately released.
Magliari said ``no malfunction'' was found on the train. He said Amtrak is assisting with the investigation.
