On September 14, according to CCTV News, a relevant person from the National Railway Group stated today (14th) that the CR450 high-speed train development project, launched in 2021, has now entered the vehicle assembly stage, and the prototype is scheduled to roll off the production line in 2024, followed by a series of tests.
During the development process, 57 new technology component research experiments have been conducted, setting new records for the train's single-line speed of 453 km/h, relative crossing speed of 891 km/h, and tunnel crossing speed of 840 km/h.
The CR450 will fill the gap in the technical standard system for high-speed trains at a speed of 400 km/h, breaking the current world record for the fastest operational speed of high-speed trains, which is 350 km/h, held by China.
The CR450 will utilize new materials such as permanent magnets, magnesium alloys, and carbon fiber, reducing the fully loaded "weight" of passengers from over 500 tons to over 460 tons, while increasing the traction power to 11,000 kilowatts. Additionally, thanks to continuously improving braking equipment, the train can stop steadily within the emergency braking distance while traveling at 400 km/h. Furthermore, its start-up acceleration response time can be reduced by about 12%, and energy consumption can be lowered by 20%.
According to previous reports from IT Home, on June 28, 2023, the CR450 test train operated at a single-line maximum speed of 453 km/h and a maximum relative crossing speed of 891 km/h on the Meizhou Bay Cross-Sea Bridge of the Fuzhou-Xiamen high-speed railway. On June 29, it operated at a single-line maximum speed of 420 km/h and a maximum relative crossing speed of 840 km/h, with new technology components performing well.
The "CR450 Technology Innovation Project" is a major scientific research project identified in the national "14th Five-Year Plan," which includes the development of new products for the Fuxing high-speed train series and several other high-speed rail technology innovation projects.
Currently, the Fuxing train has three speed levels: CR400, CR300, and CR200, corresponding to maximum continuous operational speeds of 350 km/h, 250 km/h, and 160 km/h, respectively. The current highest operational speed of China's high-speed rail trains is 350 km/h, maintained by the Fuxing CR400AF and CR400BF models.
