The reporter of economic information daily learned from China National Railway Group Co., Ltd. (hereinafter referred to as “China Railway Group”) on April 23 that recently, the world’s leading high-speed comprehensive inspection train Fuxing, independently developed by China, was put into operation. For the first time in the world, it successfully realized the open line intersection with a single train speed of 435 kilometers per hour and a relative speed of 870 kilometers per hour and the tunnel intersection with a single train speed of 403 kilometers per hour and a relative speed of 806 kilometers per hour, This marks the full launch of the “cr450 scientific and technological innovation project” incorporated into the national “14th five year plan”, which will provide the most important technical support and guidance for the development of cr450 EMUs and the most important support and guarantee for the construction of safety standard demonstration line with a speed of 350 kilometers per hour.

According to the person in charge of the science and Information Department of the State Railway Group, the State Railway Group has developed the world’s leading new high-speed comprehensive inspection train Fuxing based on the intelligent EMU of Beijing Zhangjiakou high-speed railway. The vehicle adopts 9 new technologies independently developed in China, such as eddy current braking, carbon ceramic brake disc, permanent magnet traction system and active control pantograph. It is composed of 4 motor cars and 4 trailers, which enhances the safety, reliability, efficiency and economy of EMU trains. The overall performance has reached the world leading level and filled a number of technical gaps in China.

Since April this year, the world’s leading new high-speed comprehensive inspection train Fuxing has carried out the advanced test of cr450 EMU development in Jinan Zhengzhou high-speed railway and Zhengzhou Chongqing high-speed railway. More than 60 scientific tests such as dynamics, aerodynamics, resistance and noise under high-speed operation and high-speed intersection conditions have been carried out respectively on the open line and tunnel, and the characteristic data of EMU trains, high-speed railway subgrade, tunnel and other infrastructure under different working conditions have been obtained, The relevant indicators perform well, and the change law of safety and comfort parameters related to train speed improvement is explored.
