CR450 is coming, the whole journey between Beijing and Shanghai will only take 2.5 hours

On January 9, China National Railway Group Co., Ltd. (hereinafter referred to as: National Railway Group) pointed out at the working meeting that the CR450 scientific and technological innovation project has made a major breakthrough, and the high-speed train has achieved a single train speed of 453 kilometers per hour on the open line and a rendezvous speed of 891 kilometers per hour. run. In 2024, the National Railway Group will complete the manufacture of CR450 prototype cars and carry out type tests, which are expected to be put into use by 2025.

According to the data, the experimental operating speed of the CR450 high-speed train will reach 450 km/h, and the commercial operating speed will reach 400 km/h, which is expected to become the fastest high-speed train in the world in one fell swoop, which means that if the model is in Beijing If the Shanghai high-speed rail is put into operation, it will only take 2.5 hours from Beijing to Shanghai. At present, the high-speed train running on the Beijing-Shanghai high-speed railway takes nearly four and a half hours from Beijing to Shanghai at the fastest.

"CR450 Science and Technology Innovation Project" is a major scientific research project determined by the national "14th Five-Year Plan". It will develop safer, more environmentally friendly, more energy-saving, and smarter new products. As a major achievement of China's railway technological innovation, the Fuxing train currently has three speed levels: 350, 250 and 160. CR450 will promote the demonstration of key technical indicators and the preparation of top-level index system, and carry out core technology research such as system integration, axle drive, brake control, vibration reduction and noise reduction.

At present, the development of CR450 EMU has achieved phased results. Specifically, from June 28 to 29, 2023, the State Railway Group verified the performance of a series of new technology components at higher operating speeds in the Fuqing-Quanzhou section of the Fuzhou-Xiamen high-speed railway. In the Meizhou Bay Bridge, the test train runs at a single train speed of 453 kilometers per hour and a relative rendezvous speed of 891 kilometers per hour; in the Haiwei Tunnel, the test train runs at a single train speed of 420 kilometers per hour and a relative rendezvous speed of 840 kilometers per hour. A total of 57 scientific research tests were completed, and all indicators performed well.

in addition, in 2024, the national railway group will continue to push forward key core technology research and application-oriented technological innovation, including pushing forward intelligent high-speed rail 2.0 technology research and application of Beijing-Shanghai high-speed rail intelligent upgrading demonstration; Accelerate the research and test of railway 5G private network technology; Promote China's high-speed rail technology independent innovation practice research to achieve phased results; Deepen basic research on railway safety theory, vibration reduction and noise reduction, fault mechanism, etc, increase the application of cutting-edge technology in the field of railway research efforts. At the same time, the National Railway Group will also fully complete the national railway investment tasks, promote high-quality national key projects, and put into production more than 1000 kilometers of new lines.

A number of listed companies to participate in CR450 related construction

In fact, behind the development of CR450, a number of listed companies actively participated.

time electric (688187.SH) said on December 4, 2023 at Shanghai e interaction that in the first half of 2023, the company completed the high-speed performance test of CR450 project, and the PCU-based change-over converter helped the whole vehicle to set 3 new speed records, fully verifying the company's technological leading position in the new generation of high-speed rail EMUs.

the company also disclosed in the 2023 semi-annual report that the company has completed the verification of key technologies of CR450 high-efficiency lightweight traction converter, completed the trial production of traction converter prototype, and completed the research test by using the prototype. The CR450 traction converter was replaced in the testing vehicle at a maximum speed of 453 km/h, further verifying the performance and reliability of the new converter technology. Complete the verification of key technologies of the new generation of intelligent network control system, and complete the network control system prototype development and research test.

thinking train control (603508.SH) said in response to investors' questions on August 11, 2023 that the company's LKJ-15S system has participated in CRH380 and CR450 high-speed EMU tests many times, providing technical support and scheme verification for China's high-speed EMU test innovation, and contributing thinking power to China's high-speed rail leading the world.

the company pointed out in its 2023 semi-annual report that the company actively participated in the "CR450 science and technology innovation project" of the national railway group, intelligent auxiliary train driving, heavy haul railway and other topics, actively promoted the test application of automatic train driving system and intelligent station project, accelerated the domestic alternative design of core products, and provided technical support for LKJ-15S system, LKJ2000 wireless replacement system, LSP system, etc. In the first half of 2023, the company invested a total of 63.3908 million yuan in research and development, accounting for 12% of the current operating income, 43 new computer software copyrights and 29 patents, including 11 invention patents, 11 utility model patents and 7 appearance patents.

China tong (688009.SH) said in its 2023 semi-annual report that in view of the "CR450 science and technology innovation project", the company has studied the solution of train control system for two application scenarios: new high-speed railway with a speed of more than 400 km/h and speed-up transformation of existing high-speed railway lines with good conditions, and has developed key technical equipment.

specifically, the company has independently developed the train control system technology (CR450) for higher speed and the train control system technology for higher speed, breaking through the bottleneck of safety control and equipment reliability supporting 450 km/h high-speed operation, overcoming the problem of excessive speed difference between main use and backup dual systems, improving the automatic driving capability of high-speed railway ATO system, and enriching and expanding the basic theory and engineering practice experience of train control technology for high-speed railway in China. This will also further enhance my country's railway technology self-reliance and self-improvement capabilities, consolidate my country's high-speed rail world leader position, and will strongly promote the upgrading of my country's railway network regulations.

China Central Railway Corporation (601766.SH) said that in the first half of 2023, the company pushed forward the development of major products, CR450 EMU set a new world record of 891 kilometers per hour, Yawan high-speed railway joint commissioning and test train reached 350 kilometers per hour, and the 80 kilometers per hour A/B type Chinese standard subway train successfully went offline.

ST huatie (rights protection)(000976.SZ) disclosed that the company actively cooperated with CR450 Sifang to develop a new generation of 400km CR450 project Fuxing EMU water tank and dirt tank material weight reduction plan, from water tank and new material weight reduction of dirt tank to the integrated integration of water tank, dirt tank and equipment compartment, to fully cooperate with the product lightweight goal. In 2022, the company will complete the development project of the water supply and sanitation control system for the new generation of Fuxing trains with a speed of 400 kilometers per hour, and actively carry out the design of the model parts of the research and development project of the four-way 450 kilometers of new first-class passenger room seats, which are to be applied to the first-class seats of the new generation of CR450 trains.
