CRH (China Railways High-speed) Chinese means "China High Speed ​​Railway", which is the brand name established by China Railway Corporation for China's high-speed railway system. The CRH EMU train operated by the Hexie(train) EMU on April 18, 2007 after the sixth major speed adjustment map of China Railway. In 2004, the Ministry of Railways of China launched a tender for the EMU technology for the sixth major speed increase of China Railway. Under the principle of “market-for-technology”, Canada’s Bombardier, Birmingham, France, Alstom, France and Siemens, Germany signed an agreement. Transfer key technologies to manufacturers of CNR and China South Locomotive Group.

Hexie(train) No. "Electric trains are CRH series, currently there are 8 series, CRH1, CRH2, CRH3, CRH5, CRH6, CJ1, CJ2, CJ3, CJ5, CJ6 and CRH380 series. Hexie(train) EMU is China Railway The major achievements in the full implementation of the independent innovation strategy indicate that the technical level of China's railway passenger transport equipment has reached the world's advanced level, and China has thus become one of the few countries in the world that can independently develop a 380-kilometer EMU. International first-class advanced technology such as aluminum alloy car body, high-speed bogie, high-speed pantograph and AC drive, integrated optical fiber network control, especially the large-section hollow profile aluminum alloy body used in trains, each car body The weight is about 7 tons, and the overall lightweight design of the EMU has reached the world's advanced level, with superior energy saving and environmental performance.

"Hexie" not only means speed, but also means harmony. It marks the practice of Chinese railways on the concept of harmony. Whether it is the name of "Hexie" EMU train, Hexie(train) high-power locomotive, or "China Railway" The declaration of six times of speed---the pursuit of Hexie has demonstrated and entrusted the railway people's good wishes and unremitting efforts to build a harmonious journey, build a harmonious railway, and build a socialist harmonious society. Under the circumstance that the new line capacity has yet to be formed, the implementation of the speed increase of the existing line is the most realistic and effective way to alleviate the "bottleneck" of the railway.
