The reporter learned from the China National Railway Group (hereinafter referred to as "China Railway Group") held at the China Railway Group Work Conference on January 9 that in 2024, China Railway Group will conscientiously implement the innovation-driven development strategy, accelerate the realization of high-level railway scientific and technological self-reliance and self-reliance, lead the railway modernization with scientific and technological innovation, and promote key core technology research and application-oriented technological innovation. The CR450 prototype will be manufactured and type tests will be carried out.
CAS Group Corporation.
The CR450 Science and Technology Innovation Project is a major scientific research project identified in the 14th Five-Year Plan of the People's Republic of China, which will develop new products that are safer, more environmentally friendly, more energy-saving and smarter.
As a major achievement of China's railway scientific and technological innovation, the Fuxing train currently has three speed grades: and 160. CR450 will promote the demonstration of key technical indicators and the compilation of top-level index systems, and carry out core technology research such as system integration, axle drive, brake control, shock absorption and noise reduction.
After more than two years of development, the development of CR450 EMUs has achieved phased results. As early as June 2023, China Railway Group verified the performance of a series of new technology components under higher operating speed conditions in the Fuqing-Quanzhou section of the Fuzhou-Xiamen high-speed railway. At the Meizhou Bay Bridge, the test train runs at a speed of 453 kilometers per hour in a single train and 891 kilometers per hour in relation to the rendezvousAt the Haiwei Tunnel, the test train runs at a speed of 420 kilometers per hour on a single train and 840 kilometers per hour on a relative rendezvous. A total of 57 scientific research experiments have been completed, and the indicators have performed well.

It is also understood that China Railway Group will also complete more railway technology innovation projects in 2024. Promote smart high-speed rail 20 technical research, promote the demonstration application of Beijing-Shanghai high-speed railway. Strengthen technical research in the fields of security, critical equipment, infrastructure, and operation services. Actively and steadily promote independent product research and development, testing, and promotion and application. Accelerate the research and testing of railway 5G private network technology. Promote the research on the practice of independent innovation of China's high-speed rail technology to achieve phased results. Deepen basic research on railway safety theory, vibration and noise reduction, fault mechanism, etc., and increase the application of cutting-edge technologies in the railway field.
