Lyric discussion by Tard 

I can't quite decide if it means he's hiding from a railroad bull (security officer) in a graveyard OR if he was killed by the bull and either doesn't realize it ("I can hear them a- hollerin' We got a man down here") or does is has accepted his fate ("A bone yard is the best").

I think he was killed accidentally by the bull and is subtly accepting his death by pretending he's just hiding for a while out in the graveyard.

OK, now I think he accidentally killed the bull and is hiding out in a cemetery.

An error occured.
