China Creates World's First Carbon Fiber Metro Train

China has created the world's first passenger metro train made of carbon fiber. Thanks to it, the train not only looks cool, but also weighs 11% less than regular trains, resulting in less wear on the tracks, less noise, and consumes 7% less energy. In addition, the train is equipped with autopilot and will operate at a speed of 140 km/h, almost twice as fast as current trains.
