(Xinhua) China is developing new bullet trains with a speed up to 400 kph, said a leading figure in the country's high-speed railway technology development.

Ding Rongjun, an academician of the Chinese Academy of Engineering, said that China was also researching the next generation magnetic-levitation train with a top speed of 600 kph, at a press conference Monday.
"We are now focusing on how to link TV signals to the trains so that passengers will be able to enjoy films on window-turned screens," Ding said.
A permanent magnet drive system has been added to trains and is undergoing assessment, he said, adding that automatic and unmanned drive technology will be used in the future.
The maximum speed of China's bullet trains rose to 350 kph, when the Fuxing (Rejuvenation) bullet trains started operation between Beijing and Shanghai on Sept. 21, 2017.
The Fuxing trains are a substantial upgrade on the previous Hexie (Harmony) bullet trains. Entirely designed and manufactured in China, the Fuxing train is more spacious and energy-efficient, with longer service life and better reliability.

The fastest bullet trains can do nearly 500 klicks an hour but they are not certified and approved to do that. They are French-made TGVs. Anyone can raise the top speed of an electric train. There is no glory in pushing trains to run faster. What has to be considered is how to SAFELY operate them at higher speeds, and that means, how to activate brakes in good time. A train that hurtles forward at 300 kms an hour needs ca. 6 kms to come to a stop.

And please, don't confuse maglevs with conventional trains! The fastest maglev was inaugurated in Japan ca. two years ago. It does 600 kms an hour. CHina only has a German-made maglev that was built over ten years ago and does 400 kms an hour. It is more difficult to design a SLOWER maglev, as the faster a maglev goes the safer it is. Maglevs hover while conventional trains run on wheels.
