The CRH380A is a Chinese electric high-speed train that was developed by China South Locomotive & Rolling Stock Corporation Limited (CSR) and is currently manufactured by CSR Qingdao Sifang Locomotive & Rolling Stock Co., Ltd. As a continuation of the CRH2-350 program it both replaces foreign technology in the CRH2 with Chinese developments and increases the top speed.〔(【引用サイトリンク】title=First Chinese designed HS train breaks cover: )〕 The CRH380A is designed to operate at a cruise speed of and a maximum of in commercial service. The original 8-car train-set recorded a top speed of during a trial run〔()〕 and the longer 16-car train-set temporarily held the world record for the fastest production train at . CRH380A is one of the four Chinese train series which have been designed for the new standard operating speed of on newly constructed Chinese high-speed main lines. The other three are CRH380B, CRH380C and CRH380D. The CRH380B has been developed by China North Locomotive and Rolling Stock Industry (Group) Corporation (CNR) in cooperation with Siemens, and it is manufactured by Tangshan Railway Vehicle and Changchun Railway Vehicle. The CRH380C is based on the CRH380B. It incorporates a redesigned nose and electrical equipment from Hitachi. The CRH380D is Bombardier's Zefiro 380, which is a special design for China Railways, to be produced at Bombardier Sifang (Qingdao) Transportation Ltd, a joint venture by Bombardier and CSR Sifang. ==History== The development started in early 2008, during the research procedure of CRH2-300 (later CRH2C), the CSR conducted more than 1000 technical tests covering 17 specific areas such as dynamic performance, pantograph-catenary current collection, aerodynamics, and traction performance. CSR discovered the technology to increase the maximum speed. These research findings were fed into the design for the new-generation high-speed train.〔 The original project was named "CRH2-350". On February 26, 2008,the Chinese Ministry of Science and Ministry of Railway (MOR) signed the Agreement on Joint and Independent Innovations of China High-speed Trains, CRH2-350 is one of the most important projects of this plan, the purpose is to develop Chinese designed new-generation High Speed train with continuous operating speed to be , and maximum operating speed up to . The new generations of rolling stock are expected to be used on the Beijing-Shanghai High-Speed Railway. the project officially launched in 2009, and was included in the "Eleventh Five-Year Plan"'s National technology support program for key technology and equipment development of China' s high speed train. The design work includes four categories: schematic, technical, construction, and experimentation/verification. based on the analysis of large amounts of data and experience from the operation of the Beijing-Tianjin high-speed rail. the MOR completed a series of initial system and optimized subsystem design, then provided CSR sifang with primary data and design. CSR presented more than 20 types of designs.〔(【引用サイトリンク】title=南车动车组跑出416.6公里世界最高速 )〕 After further comparison, calculation, optimization, simulation and testwork, on April 12, 2010, the final design was published on the Official conference held by Sifang. The train model was exhibited in May at the China Railway Pavilion in the Shanghai World Expo Park (IRJ July p5). On September 2009, the Ministry of Railway had ordered 100 16-car and 40 eight-car new-generation high-speed trains from CSR Sifang Locomotive & Rolling Stock, the contract worth ¥45 billion (US$6.64 billion). On April 18, 2012, the MTR ordered 9 CRH380A train sets for Guangzhou-Shenzhen-Hong Kong Express Rail Link.〔http://news.cn.yahoo.com/ypen/20120418/994153.html〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「China Railways CRH380A」の詳細全文を読む スポンサード リンク
