Another image in the Subway nearly fifty years ago. In those days, no air conditioning, just a series of large ceiling fans which blew hot fetid tunnel air onto your head. In 1968 the service was horribly unreliable, with faulty doors creating pileups in the tunnels while the train ahead was put out of service or the door locked out. You could spend ages stuck in crowded cars, with no announcements as to what was going on. What fun.
