At about 12:53 on the 21st, two test trains from Zhengzhou and Puyang respectively successfully intersected when they arrived at Junxian County, Henan Province. The recorder showed that the train speed reached 435 kilometers per hour, the relative intersection speed was 870 kilometers per hour, and the train intersection time was 0.86 seconds.

Luo Qingzhong, vice president of China Academy of Railway Sciences: This marks the full launch of the “cr450 scientific and technological innovation project” included in the national “14th five year plan”, which will provide the most important technical support and guidance for the development of cr450 EMUs. It will also provide the most important support and guarantee for the construction of 350 km / h high-speed railway safety standard demonstration line.

The test line of the fair is the Ji Zheng high-speed railway connecting Jinan, Shandong Province and Zhengzhou, Henan Province. The Fuxing train in the rendezvous test is a new type of high-speed comprehensive test train independently developed in China and leading in the world. As a new technology verification platform for high-speed EMU, it participated in the early test of cr450 EMU development. On April 12, in Badong Wanzhou section of Zhengzhou Chongqing high-speed railway, the speed of a single train in the tunnel was 403 km / h and the relative intersection speed was 806 km / h, setting a world record for the intersection speed of high-speed railway trains in the tunnel.

Luo Qingzhong, vice president of China Academy of Railway Sciences: the test train adopts 9 new technologies independently developed by China, and its overall performance has reached the world leading level, filling a number of technical gaps in China.
