Empty Trainload of Sky Lyrics

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? Was it solid? Did I ditch that class in college? Pulled the curtain from my eye I said hey hey, my my Saw a freight train yesterday It was chugging, plugging away Just an empty trainload of sky Just an empty trainload of sky Just an empty trainload of sky
