I am riding on a limited express, one of the crack trains
     of the nation.
Hurtling across the prairie into blue haze and dark air
     go fifteen all-steel coaches holding a thousand people.
(All the coaches shall be scrap and rust and all the men
     and women laughing in the diners and sleepers shall
     pass to ashes.)
I ask a man in the smoker where he is going and he
     answers: "Omaha."
