Though police are trying to determine if the men were alive or dead when they were hit by the train, investigators say the deaths appear to be accidental.
The conductor did not see the men until the train had already collided with them. However, the conductor did manage to bring the 6,500-foot-long train to a halt and remained at the scene for five hours.
No one aboard the 71-car train was reported injured, and the accident remains under investigation.
