France has tested a commercial train that can travel as fast as 357 miles per hour (575 kilometers per hour). Japan’s building a “floating” train that can reach speeds of more than 310 mph (500 kph) while levitating above the track. And China has a high-speed “ice train” that can plow across landscapes where temperatures dip as low as minus 40 degrees Fahrenheit (minus 40 degrees Celsius) in the winter, and rise to as much as 104 degrees Fahrenheit (40 degrees Celsius) in the summer.
