China Railway High-speed (abbrev. CRH); simplified Chinese: 中国铁路高速; traditional Chinese: 中國鐵路高速; pinyin: Zhōngguó tiělù gāosù) is the high-speed rail system operated by China Railways.
Hexie Hao (simplified Chinese: 和谐号; traditional Chinese: 和諧號; pinyin: Héxié Hào) (Literally: Harmony) is the designation for high-speed trains running on this rail system. At the middle of the run, all trains were marked "CRH" on the centre of the head vehicle and the side of the walls of each vehicle. Soon however, it was changed to the Chinese characters "和谐号" on all of the trains. CRH1/2A/2B/2E/5 are expected to have a maximum speed of 250 km/h (160 mph), and CRH2C/3 have a maximum speed of 350 km/h (220 mph). CRH was a major part of the sixth national railway speedup which was implemented on April 18, 2007. However, not all high-speed trains in China are named CRH.
Each train is formed of eight coaches with a capacity of between 588 to 568 people for 8-car train or 1100–1200 people for 16-car train, depending on the formation of the train. CRH1 are built by a joint venture, Bombardier Sifang Power Transportation in Qingdao, Shandong Province. China Northern Locomotive and Rolling Stock Industry (CNR), China, is supplying 60 CRH5 200 km/h eight-car trains based on Alstom technology. These trains are designed to meet UIC and EN international standards and each vehicle utilises a high-strength aluminium alloy bodyshell weighing just 8.5 tonnes.[1]

High-speed rail services were introduced in 2007 and are operated using CRH trains. These run on existing lines that have been upgraded to speeds of up to 250 km/h (160 mph) and on dedicated high speed track up to 350 km/h (220 mph).
CRH series of high-speed Power EMU are used Distributed Power, running over 200 kilometers per hour, up to 400 kilometers or more. Republic of China Ministry of Railways by 2004 onwards have to Canada Bombardier, Japan Kawasaki Heavy Industries, France Alstom, Germany Siemens AG and other foreign companies to purchase high-speed rail vehicle technology, to introduce and absorb advanced foreign technology the way, from the CNR and CSR vehicle manufacturer's production, up to a certain degree of localization and then as a basis for independent innovation. Ministry of Railways will be all the introduction of foreign technology, the joint design and production of CRH series EMUs are named "Harmony".[2] These high-speed train in the 2007 April 18 implementation of China Railway Sixth Speed be put into operation later.
Existing high-speed EMU CRH series is divided into six series, with production by manufacturers:
Within each series and then train formation, speed, etc. is divided into five major types, to 5 letters (A, B, C, D, E) said:
英文字母 | 设计速度(km/h) | 编组形式 | 车型代表 |
---|---|---|---|
A | 200~250 | 8节编组座车 | CRH1A、CRH2A、CRH5A |
B | 200~250 | 16节大编组座车 | CRH1B、CRH2B |
C | 300~350 | 8节编组座车 | CRH3C、CRH2C |
E | 200~250 | 16节大编组卧铺动车 | CRH1E、CRH2E |
Before the introduction of foreign technology, China has been conducting independent research and development Express Rail Link train, also made a lot of results (for example, EMU China Star), but China AC drive[disambiguation needed] and other core technologies are not mature, high-speed EMU's nine core technologies, including assembly, body, bogie, traction, traction control, traction transformers, traction motors, the train network control and braking system, not the hands of the Chinese domestic enterprises, domestic high-speed EMU in technology and reliability were unable to train today, compared with foreign countries. On the other hand the research process also requires a lot of time. Railway spokesman Zhang Shuguang said that due to historical reasons, China's overall level of railway technology and equipment is equivalent to developed countries 1970 1980 level, high-speed EMU technology is still in development stage, if on their own, you may need a decade or longer to catch up, can not adapt to the current economic.[3] In 2004, the Republic of China State Council and the Ministry of Railways have defined a modern railway technology and equipment, "the introduction of advanced technology, the joint design and production, to build China brand" policy. The realization of the railway "leapfrog development" is the key tasks of more than 200 kilometers per hour high speed train technology to introduce a whole, the "absorption and innovation", and in the law made independent intellectual property. In other words, the Ministry of Railways adopted a "market for technology" strategy.
April 9, 2004: State[clarification needed] held on the modern conference equipment, railway rolling stock, and issued a "study issues related to railway rolling stock and equipment the minutes", defined a railway technology and equipment modernization, "the introduction of advanced technology, the joint design and production, to build China brand," the general principle of clear modern China, the direction of railway technology and equipment, methods and objectives.
June 17, 2004: Ministry of Railways launched for use in China Railway Sixth Speed, 200 km per hour the first round of high-level EMU technology the introduction of bidding, "People Railway" and the Chinese Procurement and Bidding tender notice issued at the same time, "speed of 200 km of railways EMU project invitation to tender," the tender notice clearly the main domestic businesses, but it must obtain advanced technical support: "legally registered in the PRC, with rail EMU manufacturing capacity, and access to 200 kilometers per hour has a mature group of railway motor car design and manufacturing technology partner technical support of foreign enterprises in China (including joint ventures). " Tender documents which clearly sets out three principles: First, the transfer of key technologies must be comprehensive, the second is the price to be lowest in the world and the third is to use the Chinese brand. Master mature over the world, high-speed EMU design and manufacturing technology companies, including Siemens, Alstom, France, Japan, Kawasaki Heavy Industries and Bombardier, etc., initially had hoped to use the joint venture in China in EMU tender but was explicitly rejected the Chinese Ministry of Railways. China insists the direction of a comprehensive transfer of technology to Chinese enterprises, especially in systems integration, AC drive, and other core technologies, to allow domestic enterprises to master the core technology; and requests for domestic enterprises to foreign partners to provide technical services and training to improve the domestic enterprises to design, manufacture and technical level of quality control personnel, and ultimately to realize the localization.[4] Railway equipment manufacturers in China are free to choose foreign partners, foreign firms must be pre-bid and China's domestic manufacturers improve the technology transfer agreement signed, so the Chinese rolling stock manufacturer to comprehensively and systematically learn advanced foreign technology, which accelerate the pace of modernization of China's railways.[5]
In this round of bidding, EMU 140 orders were divided into seven packages, each package 20. Through competition and representatives from the procurement, purchasing agent, and from scientific research institutions on behalf of economic, technological, legal experts, the evaluation committee based on evaluation methods of the comprehensive review. Ultimately by the Northern China Railway Locomotive & Rolling Stock Group-owned Changchun Railway Vehicles Co., Ltd. and France Alstom co South China Railway Locomotive & Rolling Stock Group belongs to Sifang Locomotive Co., Ltd. and Japan Kawasaki Heavy Industries cooperation, Canada Bombardier in Qingdao joint venture Qingdao Quartet Bombardier Railway Transportation Equipment Co., Ltd. (BSP) three companies won the bid, were given three packets (60), 3 packages (60) and 1 package (20) in order.[5] Germany Siemens a result of an expensive technology transfer, cost of vehicle cost (prototype 350 million yuan each column, technology transfer fee 390 million euros) in the first round of bidding can not get any orders.[6][7] EMU in the first tender in payment of technology transfer payments totaling 22.7 billion yuan, accounting for the amount in the tender up to 51%.
November 2005: The Chinese Ministry of Railways and the German Siemens in the "market for technology" principle agreement, Siemens and thus access to 60 300 kilometers per hour high speed train orders.
The introduction of foreign advanced technology, high-speed train, in order to implement the "Long-term Scientific and Technological Development (2006-2020)" the requirements of high-speed rail system in the core technology innovation to meet the needs of China's railway development, in the 2008 February 26, Republic of China Ministry of Science and Railway Ministry signed the "independent innovation of Chinese high-speed train cooperation agreement Joint Action Plan".[8] Liang Buwei deployment led by the United CAS, Tsinghua University, Zhejiang University, Southwest Jiaotong University, Beijing Jiaotong University and so a large number of academicians and researchers from basic research, demonstration program, to scientific experiments, the combination of China's most outstanding scientific and industrial resources, and establish a production and research with a combination of innovation system, developing the world's highest level of high-speed trains.
Under the agreement, China's independent innovation and high-speed train joint action plan has four main aspects of the target:[9]
Republic of China Ministry of Science and started the total investment for this nearly 10 billion yuan in science and technology plan, which is by far the Chinese Ministry of Science and the largest investment program supported by a project. Project has set up dozens of issues, brought together a total of 25 key universities in China, top 11 research institutes, national laboratories and 51 engineering research centers, including 68 academicians, professors more than 500 people, more than 200 researchers, project technical staff on the people. In addition, the Ministry of Science and also with the speed of 400 km of high-speed detection vehicles and deployment of 500 km per hour of high-speed trains were arranged based rehearsal "863 Project" and "973 Project", to form a series of key technologies from basic research to develop and then important equipment developed systems engineering.[10]
