NYC subway air conditioning 1956

While other subway passengers perspire in the warm and humid underground station, Paul Forman appears cool and comfortable in the experimental air conditioned train which made its first run in New York City, July 9, 1956. The test run, which included six air conditioned cars and two old cars, was made on the East Side IRT line. The new cars provide soft music, modern design, air cooling units, deodorizers and filters to reduce germs. When the train left Grand Central Station the temperature was 89-degrees in the old cars while the new cars registered 76.5 degrees. (AP Photo/Harry Harris)
