Saw a freight train yesterday It was chugging, plugging away 'Cross a river, trestle so high Just a boxcar blue Showing daylight clear through Just an empty trainload of sky Well, it hit me and it hurt me Made my good humor desert me For a moment, I was tempted to fly To the Devil or the Lord As it hung there like a sword Just an empty trainload of sky Was it spirit?
