Japan is famous for its state-of-the-art high-speed railway system. In 2015, its Magnetic Levitation or, Maglev train, which gets its name because it hovers 10 cm above the tracks, set a new speed world record of 375 mph (603km/hr). Now the innovative island nation wants to build a train that features a mirror-like exterior and blends in so well with the environment, that it will be practically "invisible."
