A villager called police after spotting the body while walking home. 
A ticket was found on him showing he had caught the 7.15pm train from Udon Thani the night before. 
His body was sent for preliminary checks at the district hospital, where doctors found two wound in his head, indicating he had been hit with a hard object. 
Police intend to interview officials who had been on the same train to find out what happened.
