Japan’s next-generation maglev train continues to stun observers with its speed and engineering. During a recent demonstration, reporters were left in disbelief as the $70 million prototype shot past them at 500 km/h (311 mph) — a velocity achievable thanks to magnetic levitation technology that eliminates wheel friction entirely. Developed for the future Chūō Shinkansen line, the train rides on powerful superconducting magnets that lift it several centimeters above the track, allowing it to gli
