Ever since China began building its first high-speed railway in 2004, the country’s high-speed rail construction has developed rapidly. In 2016, four major high-speed rail lines opened, expanding the total length of China’s high-speed rail network to more than 22,000 kilometers, top in the world. In April of this year, high-speed rails were rated the best of the “four innovations of modern China” that are the most appealing to youths from 20 countries involved in the Belt and Road Initiative. High-speed rails are becoming a “Chinese specialty” that many foreign youngsters want to sample.
At 11:05 a.m. on June 26, 2017, two newly developed electric multiple unit (EMU) trains, named Fuxing (literally, “rejuvenation”), were officially launched on the Beijing-Shanghai highspeed railway.
The Fuxing train, to which China possesses complete intellectual property rights, is a new model following the CRH model.
Lu Dongfu, general manager of China Railway Corp, believes that “the launch of the new bullet trains means China’s high-speed trains make a major leap forward in the country’s push to become a global tech power.”
How Great Are the New Bullet Trains?
First, the EMU trains received a speed-boost. The number“400” in the official names of the two Fuxing models, CR400AF and CR400BF, indicates that the trains typically travel at speeds of around 350 kilometers per hour but can reach 400 kilometers per hour, an increase of 150 and 50 kilometers per hour compared to the CRH model.
Second, the EMU trains widely adopted Chinese standards. They are built according to a number of technical standards including unified Chinese standards, railway industry standards and requirements of the China Railway Corp, with Chinese standards covering 84 percent of all requirements. Independent development of the new technologies in the trains, including overall design and every key component, has left China in control of the intellectual property rights. And every track leads to greater connectivity.
Third, the new trains provide better security. To guarantee safety, the Fuxing model brings its own “doctor” along on every trip. The new model has a powerful safety monitoring system with more than 2,500 sensors. The sensors monitor the state of the entire train, and if something ever goes wrong, the monitoring system sounds an alarm and can even take automatic measures such as reducing speed or even stopping the train. An energy absorption device to diminish collisions is placed at the joint of the locomotive and carriages of the train. The device can passively protect the train completely in the event of a low-speed collision.
