From April 18th to May 18th, it was the sixth major speed-transition period for China’s railways. 26 technological innovations ensured the safe and effective implementation of the speed increase of the railways. These innovative achievements are: 1. Complete sets of technologies. Mastered the speed of existing lines. 200 km and above speed-up system integration technology. A technology standard system for speed increase of 200 km/h or above was initially formed. For the first time, different types of trains were operated in parallel. For the first time, the passenger train tracking interval was 5 minutes. II. EMUs. Comprehensive and systematic introduction of foreign advanced and mature EMU designs
