The Campaign to raise the speed of railway travel in China or the China Railway Speed Up Campaign (中国铁路大提速) refers to initiatives undertaken by the Ministry of Railways from 1997 to 2007 to increase the speed of train travel in China by improving the nation’s railways. The campaign was implemented in six rounds and increased average speed of passenger trains in China from 43 km/h to 70 km/h. ==Overview== In 1993, commercial train service in China averaged only 48 km/h (30 mph)〔(Chinese) (高铁时代 ''中国国家地理网'' ) 2010-04-07〕 and was steadily losing market share to airline and highway travel on the country's expanding network of expressways. The MOR focused modernization efforts on increasing the service speed and capacity on existing lines through double-tracking, electrification, improvements in grade (through tunnels and bridges), reductions in turn curvature, and installation of continuous welded rail. Through five rounds of "speed-up" campaigns in April 1997, October 1998, October 2000, November 2001, and April 2004, passenger service on 7,700 km (4,785 mi.) of existing tracks was upgraded to reach sub-high speeds of 160 km/h (100 mph).〔(Chinese) ("中国铁道部六次大提速" ''Sina News Center'' ) Accessed 2010-10-04〕 A notable example is the Guangzhou-Shenzhen Railway, which in December 1994 became the first line in China to offer sub-high speed service of 160 km/h using domestically-produced DF-class diesel locomotives. The line was electrified in 1998, and Swedish-made X 2000 trains increased service speed to 200 km/h (124 mph). After the completion of a third track in 2000 and a fourth in 2007, the line became the first in China to run high-speed passenger and freight service on separate tracks. The completion of the sixth and final round of the "speed up" campaigns in April 2007 brought HSR service to more existing lines: 423 km (263 mi) capable of 250 km/h (155 mph) train service and 3,002 km (1,865 mi) capable of 200 km/h (124 mph). Some 7,000 km of tracks could accommodate trains traveling at speeds up to 160 km/h (99 mph).〔((Chinese) )〕 In all, travel speed was increased on 22,000 extended km (13,700 extended mi), or one fifth, of the national rail network, and the average speed of a passenger train improved to 70 km/h. The introduction of more non-stop service between large cities also helped to reduce travel time. The non-stop express train from Beijing to Fuzhou shortened travel time from 33.5 to less than 20 hours. In addition to track and scheduling improvements, the deployment of the CRH series trains raised travel speed. During the sixth railway speedup campaign, 52 CRH trainsets (CRH1, CRH2 and CRH5) were put into operation, service as 280 train numbers. By the end of 2007, there were planned to have 158 CRH trainsets, 514 train numbers in operation.〔(CCTV International )〕 The new trains sliced 2 hours off of the 1,463 km trip between Beijing and Shanghai to a journey of just under 10 hours. Travel times from Shanghai to Changsha (1,199 km) fell by 1.5 hour to 7.5 hours and the trip to Nanchang was halved. 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「Campaign to raise the speed of railway travel in China」の詳細全文を読む スポンサード リンク
