World's longest train speed ahead of high-speed rail

Xinhua Guangzhou December 26, Xinhua (reporter Zi Zhongxi Chungkin Chen Liming nearest) 26th 9 o'clock, Wuhan, Changsha, Guangzhou, at the same time the first Chinese-made 350 kilometers per hour harmony high-speed train.　　At this point, after 4.5 of the construction, the world's first built the longest, operating the highest speed of the Wuhan high-speed railway officially put into operation.　　This line can not only meet the needs of people's convenient travel, but also greatly acquitted the Guangzhou freight pressure, the "Pan-Pearl River Delta" Economic and social development injected vigor. Wuhan is an important part of Beijing-Guangzhou high speed railway in China's medium and long term railway network planning, which started construction in June 2005.　　Line across Hubei, Hunan, Guangdong Three provinces, operating mileage of 1069 kilometers, using the world's most advanced domestic "harmony" high-speed train and traction power supply, train control systems, 350 km/h, the maximum traffic density of up to 3 minutes per column. Ministry of Railways Transport bureau Secretary Zhang First, Wuhan December 9 successful test run, Harmony high-speed train from Guangzhou South Station to Wuhan station, less than 3 hours.　　Meanwhile, the train runs 394.2 kilometers per hour, creating the highest operating speed of the world's high-speed railway under the condition of two cars being heavily linked. Wuhan in the near future will be open daily 28 pairs of high-speed EMU, of which Guangzhou to Wuhan every day to open 21 pairs, Guangzhou to Changsha every day to open 5 pairs, Changsha to Wuhan every day to open a row of 2 pairs. Wuhan-Guangzhou travel time from the original about 11 hours shortened to the present 3 hours, Changsha to Guangzhou direct only need 2 hours.　　High-tech content is Wuhan's biggest bright spot. "In addition to the domestic speed of 350 kilometers per hour harmony high-speed train, Wuhan paved with the world's advanced level of railway ballastless track." Compared with the traditional ballast track, this kind of track has the characteristics of stable structure, no maintenance and long life, which ensures the smoothness of the line and improves the comfort of passengers.　　"Huawu Vouxiengon, chief engineer of the Ministry of Railways. In addition, Wuhan Bridge engineering Technology to create a number of the world's first. All bridge mileage accounts for almost half of the total line mileage.　　Built by the China Railway Bridge, Wuhan Tian Xing Chau Yangtze River bridge is 4657 meters, the main span of 504 meters, the bridge Road paved 4 lines, set a span, load, speed, width of 4 world first. The train operation control system is in the world-class level. Control system technology at present, only a few countries in the world to grasp.　　Wuhan control system, can meet the speed of more than 350 kilometers per hour, moving the workshop within 3 minutes of train Operation command and control requirements, to achieve the operation of high speed, high-density and high reliability. The existing Guang is one of China's busiest railway lines. Most sectors through capacity utilization of more than 85%, of which the Zhuzhou to Hengyang section of more than 100%, has been seriously hyper-saturated, transport organizations lack the necessary mobility, the Beijing-Guangzhou channel Transport "bottlenecks."　　It is speculated that the Wuhan Channel 2010-Year passenger density cargo capacity gap of 44.6 million tons, the existing transport capacity can not meet transport needs.Wang, spokesman for the Ministry of Railways, said that the Wuhan of the Pearl River Delta economy from labor-intensive traditional industries to capital-intensive modern industries, the ' Pan Pearl River Delta ' region of the regional economic structure to complement each other, promote the coordinated development of regional economy, promote China's social resource conservation and environmental protection is of great significance. "After the Wuhan operation, the Wuhan Railway passenger and freight line transportation becomes possible." Wuhan with the construction of the Shanghai-Han Rong Railway, Shanghai-Kunming Railway passenger line and other railway links, can make the regional railway network more flexible, and the country's passenger and freight communication more convenient and fast. In particular, the implementation of passenger and freight line operation, will be greatly discharged both Guangzhou capacity, effectively relieve the tension of freight capacity, to maximize the relationship between the livelihood of coal, oil, food and other key materials transport needs.　　"he said.　　At present, China, including Beijing-Shanghai high-speed railway and other key projects in the construction of 277, Zhengzhou-XI ' an, Fuzhou-Xiamen, a large number of key projects will be completed, the construction of the passenger dedicated line and inter-city railway projects have more than 40, the construction scale of more than 10,000 kilometers. This year, China launched a new line of railways up to 5600 kilometers, the railway business mileage reached 86,000 kilometers, ranked second in the world. By 2012, China's railway business mileage will reach 110,000 kilometers, of which the high-speed railway mileage of 13,000 kilometers, well-developed network to take shape, railway transport bottlenecks in the basic relief.
