The film does not end, is never rewound, and each frame is seen twice in a single viewing: a palindrome illustrating the Chicago "elevated," the backbone of the city, shuttling its oblivious passengers to death. "Hypnotic study in motion." – Nora Sayre, The New York Times Note: Shown head to tail, then tail to head. Preserved by the Academy Film Archive in 2014.
