Dateline Tokyo journalist Charli James went behind the scenes with the Shinkansen bullet train cleaning crew to film their “7-Minute Miracle” turnaround.
The Shinkansen is a network of high-speed railway lines in Japan operated by four Japan Railways Group companies. Shinkansen literally means new trunk line, referring to the high-speed rail line network. The maximum operating speed is 320 km/h (200 mph). The Tōkaidō Shinkansen is the world’s busiest high-speed rail line. Carrying 151 million passengers per year, it has transported more passengers (over 5 billion, entire network over 10 billion) than any other high-speed line in the world.
