By the end of the year, China's high-speed rail had 35000 kilometers of traffic, ranking first in the world

On Tuesday, China National Railway Group Co., Ltd. (hereinafter referred to as "China Railway Group") held a conference on scientific and technological innovation. The conference revealed that China has built the world's most modern railway network and the most developed high-speed railway network. By the end of this year, the national railway business mileage will reach more than 139000 kilometers, including 35000 kilometers of high-speed railway, ranking first in the world, with high-speed, heavy load and high original height Cold railway technology has reached the world's leading level How does

define China's leading position in the world in terms of high speed, heavy load and plateau cold

"at present, China has systematically mastered the complete set of high-speed railway construction technology under various complex geological and climatic conditions, overcome a series of worldwide technical problems in the field of railway engineering construction; comprehensively mastered the manufacturing technology of 200-250km / h and 300-350km / h EMUs, and constructed a mature and complete high-speed railway technology system covering different speed levels. "The head of China Railway Group said that, in particular, the self-developed Fuxing EMU with the world's leading level has successfully achieved 350 km / h commercial operation on Beijing Shanghai high speed railway and Beijing Tianjin Intercity Railway, setting a new benchmark for the construction and operation of the world's high-speed railway

has completed the operation test of 30000 ton heavy haul combined train by operating 20000 ton heavy haul combined train in general. The annual maximum traffic volume has exceeded 450 million tons. Daqin Railway has become the world's largest heavy haul line in the last year. At present, China has built a heavy-duty railway technology system covering different axle load grades, and has mastered the key technologies of 30 ton axle load heavy-duty railway rolling stock and line facilities. " With the launching and operation of heavy-duty railway such as Wari and Haoji, China's heavy-duty railway technology has entered the system upgrading stage. "Said the head of the National Railway Group According to the meeting on the same day of

, the Qinghai Tibet railway has been running safely and stably for 13 years since its opening, and the achievements of tackling the three major worldwide engineering problems of permafrost, high cold and anoxia, and ecological vulnerability have withstood the test of operation practice Relying on the construction and operation of Qinghai Tibet railway, Lhasa Japan Railway and Lhasa forestry railway, China has systematically mastered the key technologies of plateau railway construction, operation and maintenance. "The head of China Railway Group said that the technical problems such as frost heave control of Harbin Dalian high speed railway, the world's first high-speed railway in the cold region in winter, have been effectively solved, and relevant experience has been successfully applied to Harbin Jiaxing and Harbin Mudanjiang high speed railway, further enhancing the adaptability of China's high-speed railway technology The reporter of

science and Technology Daily also learned from the railway science and Technology Innovation Conference that China has successfully developed the intelligent Fuxing EMU and realized the automatic driving function of 350 km / h for the first time in the world. China has become an important leader in the development of Intelligent Railway in the world According to the data of the

Innovation Conference, relying on the key projects such as intelligent Jingzhang and intelligent Jingxiong, we have vigorously promoted the innovation of intelligent construction, intelligent equipment, intelligent operation, intelligent maintenance and intelligent service technology, and preliminarily constructed the technical system, data system and standard system of intelligent railway

in addition, China's railway has also built the world's largest railway 12306 Internet Ticketing system, with more than 80% of the tickets sold on the Internet; it has promoted the integration of the railway network and the Internet, and launched innovative service initiatives such as brush face verification, online seat selection, code scanning arrival, station car Wi Fi, online meal booking, and electronic ticket, which are widely welcomed by the market

in 2019, the national railway is expected to complete 3.6 billion passengers, an increase of 92% over 2012. Among them, EMU is expected to send 2.31 billion passengers, an increase of 3.4 times over 2012. The main indicators of railway transportation rank first in the world. Major progress has been made in the construction of key overseas projects, such as China Laos railway, Yawan high speed railway, Hungary Serbia railway, etc., which has driven China's railway technical standards and the whole industrial chain to go global as a whole, and the world influence of China's railway has increased unprecedentedly.
