China Railway completes tests on high-speed trains at speeds up to 453 km/h, the fastest in the world
China Railway said on Saturday that it has successfully completed performance tests of new high-tech components critical to CR450 high-speed trains at speeds exceeding 400 kilometers per hour (km/h), said to be the fastest in the world, marking another milestone in China's world-leading high-speed rail technology.
In an effort to accelerate the development of a new generation of high-speed trains that are faster, safer, more environmentally friendly, energy-efficient and intelligent, China Railway conducted testing along a section of the railway from Fuqing to Qianzhou in East China's Fujian Province, the Global Times learned from China Railway on Saturday.
On Wednesday, the test train successfully ran on the Meizhou Bay cross-sea bridge at a single-train speed of 453 km/h and a relative velocity of 891 km/h. On Thursday, the test train operated in the Haiwei Tunnel at a single-train speed of 420 km/h and a relative velocity of 840 km/h.
The new technology components underwent effective performance tests, demonstrating excellent performance across various indicators. This achievement marks a significant milestone in the development of the CR450 high-speed train, laying a solid foundation for the implementation of the CR450 Technology Innovation Project, China Railway said.
CR450 represents a train designed with an operating speed of 400 km/h. Currently, the fastest operating speed of high-speed trains in China is 350 km/h, which is also the highest high-speed rail operating speed in the world. The fastest operating speeds for high-speed trains in Japan and France are set at 320 km/h, according to media reports.
At a speed of 400 km/h, the train would shorten the trip from Beijing to Shanghai to 2.5 hours. At such a speed, the journey from New York to Washington DC in the US could be cut to just under 55 minutes, which takes three to four hours by car or train.
Unlike the six times major speed increases which occurred between 1997 and 2007 when China was still striving to catch up with global frontrunners, more recent speed raises, including the current CR450 project, have helped maintain China's advantage in operating the world's fastest trains, Sun Zhang, a railway expert from Shanghai Tongji University, told the Global Times on Saturday.
Sun recalled vividly that the sixth speed raise which happened on April 18, 2007, when China raised its national train speeds from the 160 km/h to 200 km/h. After China put into operation of its high-speed trains into use in 2008, the country quickly took the lead with trains running at a current 350 km/h.
After reaching a certain speed, any further speed raise is not going to be an easy task, Sun said, noting that by adding 50 km/h, the CR450 will represent another leap in quality and a milestone in the development of China's high-speed rail.
On Wednesday, test trains travelled at a speed of 453 km/h on the Meizhou Bay Bridge from opposite directions, passing each other.
On Thursday, trial trains were operated at a speed of 420 km/h on the Haiwei Tunnel from opposite directions, passing each other.
China has also been modifying its railway infrastructure as it works on developing faster trains. Some new high-speed railway lines have been built under higher standards that will allow more technologically advanced trains to operate at higher speeds in the future.
Currently, the fastest bullet trains in China operate at speeds of 350 km/h along several lines, including the Beijing-Shanghai High-Speed Railway, the Beijing-Tianjin High-Speed Railway, the Beijing-Zhangjiakou High-Speed Railway and the Chengdu-Chongqing High-Speed Railway.
According to the test runs, the trains performed well with the new components, showing the achievement of China's development of the CR450 EMU, a faster bullet train. The tests also laid a solid foundation for the smooth operation of the "CR450 Science and Technology Innovation Project".
According to the railway company, the project is a major scientific research undertaking that is part of the National 14th Five-Year Plan (2021-25). It includes the development of new types of the Fuxing EMU.
To ensure the successful development of the next generation of EMU trains, it is necessary to carry out a large number of simulation calculations, bench tests and line tests of new technological components.
A total of 57 scientific research tests were carried out during the trial runs to verify the technical feasibility and performance stability of the new components of the CR450 EMU. The experiments were jointly carried out by research institutes, enterprises and universities, including the China Academy of Railway Sciences, the CRRC, Beijing Jiaotong University, Southwest Jiaotong University and Central South University.
Data on the components were collected at different speeds and in various areas along the railway such as in tunnels, on bridges and around curves.
The experiments have shown that the application of the new technologies has improved some indicators on the train. It also shows that China's technologies on high-speed railway safety, power, energy consumption, vibration, acceleration performance and braking stability will continue to lead the world.
It also provides important support for the development of faster, safer, greener and smarter CR450 EMUs, according to the company.

Tech upgrades power Chinese trains to 453 km/h during tests
Bullet trains travelled at speeds of 453 km/h and 420 km/h on test runs recently, demonstrating further evidence of China's rapid development of high-speed trains, the national railway operator China State Railway Group said on Saturday.
The test runs were carried out along the high-speed railway linking Fuzhou and Xiamen in Fujian province to gauge the performance of the trains after they had been outfitted with new technological components.On Wednesday, test trains travelled at a speed of 453 km/h on the Meizhou Bay Bridge from opposite directions, passing each other.
