Japan's maglev train sets world record: 603 kph

A Japan Railway maglev train hit 603 kilometers per hour (374 miles per hour) on an experimental track in Yamanashi , setting a decisive new world record. Central Japan Railway Company owns this fastest passenger train and is planning to have a train in service in 2027 on the 286-km route between Tokyo and the central city of Nagoya. Japan had launched its first bullet train named Shinkansen in 1964.

Right now, China operates the world's fastest commercial maglev, which has hit 431 kilometers per hour (268 miles per hour) on a route through Shanghai.

How Maglev Trains Work-

Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speeds.

The two notable types of maglev technology are:

Electromagnetic suspension (EMS), electronically controlled electromagnets in the train attract it to a magnetically conductive (usually steel) track.
Electrodynamic suspension (EDS) uses superconducting electromagnets or strong permanent magnets that create a magnetic field which induces currents in nearby metallic conductors when there is relative movement which pushes and pulls the train towards the designed levitation position on the guide way.
