China launches world's fastest train!

China has unveiled world's fastest train maglev this is capable to attain the top speed to 600 km per hour. China's train maker CRRC released the high-speed train at a railway industry trade fair, in Berlin, Germany. According to the manufacturing company, the train is developed with indigenous technology developed by China. It said that the train prototype has already conducted a successful test run in China. Since the 1980s, some commercial trains have employed magnetic levitation, or maglev, which uses an electrified magnetic field to propel or pull objects at high speeds. Today, maglev trains are used in South Korea, China, and Japan. China already has a running service for Maglev train in Shanghai that connects the main city with the airport. Maglev or Magnetic levitation use the electromagnetic force to literally “levitate” the whole train above the track with no physical contact between the rail and the body, which produce no friction. The train is levitated because of the strong force of repulsion between the poles of the magnets on the rail and those on the train’s body.
