Riding to modernity: Passengers walk on the shiny new subway platform at Beijing Capital International Airport’s newly constructed Terminal 3 on July 19. The Airport Line began running on that day in preparation for August’s Olympic Games. During the games, from Aug. 8 to 24, more than 68 million people rode Beijing’s subway—with the daily number peaking at 4.9 million on Aug. 22—and the punctuality rate during the Olympics was 99.8 percent, the Chinese news agency Xinhua reported.
