According to China Railway Group Co., Ltd., the CR450 high-speed train prototype was released in Beijing on the 29th, marking a major breakthrough in the "CR450 Technology Innovation Project", which will greatly enhance China's railway technology innovation level and self-reliance, further consolidate and expand China's leading advantage in high-speed rail technology in the world. The relevant person in charge of the Ministry of Science and Information Technology of China Railway Group introduced that since the 18th National Congress of the Communist Party of China, China Railway has independently developed a large number of technological innovation achievements represented by the Fuxing high-speed train, and built a complete high-speed railway technology system covering three major fields: high-speed railway engineering construction, equipment manufacturing, and operation management. China's high-speed railway has achieved historic progress from catching up to leading, and high-speed railway technology has set an international benchmark. In order to further consolidate and expand China's leading edge in high-speed rail technology in the world, and better serve and support Chinese path to modernization, China Railway Group takes the lead in organizing domestic research institutes, universities, enterprises and other advantageous research forces to form a joint innovation team to carry out collaborative research. In 2018, exploration began in the "unmanned zone" of commercial operation technology with a speed of 400 kilometers per hour, studying the basic theory and key technologies of high-speed rail under the operating conditions of 400 kilometers per hour, and making a lot of technical accumulation and demonstration; In 2021, the "CR450 Technology Innovation Project" will be officially implemented, starting the research and development of CR450 high-speed trains with a speed of 400 kilometers per hour and the research on complete sets of high-speed rail infrastructure technologies; In 2022, the overall technical specifications for CR450 high-speed trains were released, and parameter tests and extensive simulation calculations were conducted for the development of CR450 high-speed trains; From 2022 to 2023, new technology component replacement tests were conducted for CR450 high-speed trains on the Mianyang and Fuzhou Xiamen high-speed railways, verifying key new technologies and component performance; In 2024, the production of prototype cars was officially launched, and intelligent manufacturing technology was widely applied to strengthen quality control, ensuring the smooth production of CR450 high-speed train prototype cars. It is understood that the CR450 high-speed train prototype has internationally leading indicators such as operating speed, energy consumption, interior noise, and braking distance. One is higher speed. The experimental speed is 450 kilometers per hour, and the operating speed is 400 kilometers per hour. After commercial operation in the future, it can further compress the distance between time and space, making passenger travel more convenient and efficient. Secondly, it is safer. The braking distance is shorter and the running stability is better. With the increase of operating speed, the braking distance is basically the same. Thirdly, it is more energy-efficient. The running resistance of the high-speed train is reduced by 22% and the weight is reduced by 10%. Fourthly, it is more comfortable. The comfort index is better, the interior noise is reduced by 2 decibels, and the passenger compartment service space is increased by 4%, which can provide diversified, convenient, and personalized services for passengers and improve the riding experience. Five is more intelligent. The fields of driving and control, intelligent driver interaction, safety monitoring, and intelligent passenger services have all been comprehensively upgraded. The CR450 high-speed train sample released this time includes two trains, among which the CR450AF is manufactured by CRRC Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. According to Tao Guidong, the deputy chief engineer of the company, the front design of the CR450AF is inspired by the "flying arrow", with sharp edges on both wings imitating the ancient Chinese "arrowhead", which has great speed impact. The color scheme of the car body ribbon adopts "national flag red" and "glass yellow", and its shape is derived from the "pen edge" in Chinese calligraphy, highlighting the "Chinese style". The overall design of the vehicle fully embodies Chinese speed, Chinese wisdom, and Chinese culture. The relevant person in charge of the Ministry of Science and Information Technology of China Railway Group introduced that the CR450 high-speed train is a vivid practice of the national innovation driven development strategy, a comprehensive demonstration of China's scientific and technological innovation and high-end equipment manufacturing strength, fully demonstrating the advantages of the socialist system. It is of great significance to promote the high-level scientific and technological self-reliance of China's railways, lead the development of new quality productivity of railways with scientific and technological innovation, and build a modern railway industry system. Next, China Railway Group will arrange a series of line tests and assessments for CR450 high-speed train samples, further testing various performance indicators, continuously optimizing technical indicators, and striving to put them into commercial operation as soon as possible.
