China News Service, Beijing, April 23 (Reporter Zhou Yin) China National Railway Group Co., Ltd. (hereinafter referred to as China National Railway Group) disclosed on the 23rd that the world-leading new Fuxing high-speed comprehensive inspection train independently developed by China has recently been put into operation.
According to the person in charge of the Science and Information Department of China National Railway Group, the car participated in the preliminary test of the development of the CR450 EMU as a new technology verification platform for high-speed EMUs. 403 kilometers per hour, the relative intersection speed reaches 806 kilometers per hour; on April 21, the Jinan-Zhengzhou high-speed railway Puyang-Zhengzhou section successfully achieved a single train speed of 435 kilometers per hour and a relative intersecting speed of 870 kilometers per hour, creating a high-speed rail EMU train open line and tunnel intersection speed world record.
This marks the full launch of the "CR450 Science and Technology Innovation Project" included in the national "14th Five-Year Plan", which will provide the most important technical support and guidance for the development of the CR450 EMU, and will also provide the most important support for the construction of the 350 km/h safety standard demonstration line and guarantee.
The person in charge said that China National Railway Group, together with Chinese high-speed rail design and manufacturing related enterprises, universities, and scientific research institutes, has developed the world's leading new Fuxing high-speed comprehensive inspection train based on the Beijing-Zhangjiakou high-speed rail intelligent EMU.
The car adopts 9 new technologies such as eddy current braking, carbon ceramic brake disc, permanent magnet traction system, and active control pantograph independently developed by China. It consists of 4 EMUs and 4 trailers, which enhances the safety of EMU trains. The overall performance has reached the world's leading level.
The person in charge said that the world's leading new Fuxing high-speed comprehensive inspection train went online and successfully carried out a series of scientific experiments, which verified the performance of the new technology equipment, explored the boundary conditions for the operation of the EMU under higher speed conditions, and further enriched and expanded the The basic theoretical research results and engineering practice experience of China's high-speed railway are of great significance to improving the self-reliance and self-reliance of railway technology and consolidating China's leading position in the world of high-speed railway.
