Dear MEL Topic Readers,

China to introduce new generation of driverless trains in 2020

Magnetic Levitation (Maglev) Trains use magnetic forces to lift, propel and guide a vehicle over a track. Unlike conventional trains, Maglev trains have no steel wheels, which makes it faster, quieter, and cheaper to operate because of the absence of rolling friction. For example, the high-speed Maglev train system being constructed in Japan runs at a top speed of 500 kilometers per hour. Also, maglev railcars can be wider, which allows wider interior space. Another benefit of the maglev train is that it can ascend higher grades, as much as 10 percent, than conventional trains, which can only climb up to four percent. All in all, Maglev trains have a few considerable advantages either for long distance routes or just intercity connections.

Just like the world longest highspeed railway network, China is the leader in Maglev technology and operation. There already are a highspeed line in Shanghai, a medium-speed line in Changsha in Hunan province, and a low-speed Maglev subway in Beijing. Now, they are planning to have another one in Changsha that is driven without a human operator onboard.

Enjoy reading and think which is safer and dependent, a human or an AI driver especially for high-speed trains.
