|} The Beijing–Shanghai High-Speed Railway (or Jinghu High-Speed Railway from its Chinese name) is a long high-speed railway that connects two major economic zones in the People's Republic of China, the Bohai Economic Rim and the Yangtze River Delta.〔(Beijing-Shanghai High-Speed Line, China ). Railway-Technology.com, 2008-09-25.〕 Construction began on April 18, 2008, and a ceremony to mark the completion of track laying was held on November 15, 2010.〔 The line opened to the public for commercial service on June 30, 2011.〔(【引用サイトリンク】title=Beijing-Shanghai high-speed train makes debut )〕 This rail line is the world's longest high-speed line ever constructed in a single phase. Under former Minister of Railways Liu Zhijun, the railway line was the first one designed for a maximum speed of 380 km/h in commercial operations. The non-stop train from Beijing South to Shanghai Hongqiao was expected to finish the journey in 3 hours and 58 minutes,〔 〕 averaging , making it the fastest scheduled train in the world, compared to 9 hours and 49 minutes on the fastest trains running on the parallel conventional railway.〔 〕 However, following Liu Zhijun's dismissal in February 2011, several major changes were announced. First, trains would be slowed to a maximum speed of , reducing operating costs. At this speed, the fastest trains would take 4 hours and 48 minutes to travel from Beijing South to Shanghai Hongqiao, making one stop at Nanjing South.〔 〕 Additionally, a slower class of trains running at would be operated, making more stops and charging lower fares. == Specifications == The Beijing–Shanghai High-Speed Railway Co., Ltd. was in charge of construction. The project was expected to cost 220 billion yuan (about $32 billion). An estimated 220,000 passengers are expected to use the trains each day,〔 which is double the current capacity.〔(Construction of Beijing to Shanghai High-speed Railway Kicks Off ). CRIEnglish.com, January 2008. (accessed: 2008-09-25)〕 During peak hours, trains should run every five minutes.〔 1,140 km, or 87% of the railway is elevated. There are 244 bridges along the line. The 164-km long Danyang–Kunshan Grand Bridge is the longest bridge in the world,〔 〕 the 114-km long viaduct bridge between Langfang and Qingxian is the second longest in the world, and the viaduct between Beijing's 4th Ring Road and Langfang is the fifth longest. The line also includes 22 tunnels, totaling 16.1 km. 1,268 km of the length is ballastless. According to Zhang Shuguang, then deputy chief designer of China's high-speed railway network, the designed continuous operating speed is , with a maximum speed of up to . The average commercial speed from Beijing to Shanghai was planned to be , which would have cut the train travel time from 10 hours to 4 hours.〔 〕 The rolling stock used on this line consists mainly of CRH380 trains. The CTCS-3 based train control system is used on the line, to allow for a maximum speed of 380 km/h of running and a minimum train interval of 3 minutes. With power consumption of 20 MW and capacity of about 1,050 passengers, the energy consumption per passenger from Beijing to Shanghai should be less than 80kWh. 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「Beijing–Shanghai High-Speed Railway」の詳細全文を読む スポンサード リンク
