35000 km: a new starting point and journey for China's high-speed rail
35000 kilometers, a proud figure - China National Railway Group Co., Ltd. recently released data shows that by the end of this year, China's railway business mileage will be more than 139000 kilometers, of which the high-speed railway will be more than 35000 kilometers, ranking first in the world. (Guangming Daily, December 1) what does
5000 km mean? Everyone who has ever sat on China's high-speed rail has their own answers. These answers may be different, but I believe one thing is the same: China's high-speed rail has brought rapid changes to China.
: the development of self breakthrough and continuous innovation. Ten years ago, China's high-speed rail technology, construction and management were blank, but the economic and social development of high-speed rail demand is very urgent. In 2007, China's first EMU set out from Shanghai station, ushered in the earliest era of EMU; then in 2008, Beijing Tianjin intercity high-speed rail officially opened, accelerating the arrival of China's era of high-speed rail. After that, China's high-speed rail really made great progress: in 2018, the total business mileage of China's high-speed rail has reached 30000 kilometers, 44.5 times of that in 2008, ranking first in the world; major progress has been made in the construction of overseas key projects such as China Laos railway, Yawan high-speed rail, Hungary Serbia railway, etc., which has driven China's railway technical standards and the whole industrial chain to achieve the overall "going out" It can be said that the development of China's high-speed rail is the development of self breakthrough and continuous innovation. This development is not only a simple increase in operating mileage, but also a multi-level, multi angle and multi field development in economy, society, people's livelihood, science and technology, culture, etc.
accelerate scientific and technological innovation and achieve high-quality development. High speed rail technology has a high content of science and technology. In recent years, China's research and development in core technology has been fruitful. For example, China has systematically mastered the complete set of high-speed rail construction technology under various complex geological and climatic conditions, overcome a series of world-wide technical problems in the field of Railway engineering construction, and comprehensively mastered the manufacturing technology of EMUs with a speed of 200
1250km / h and 300
1350km / h, A mature and complete high-speed railway technology system covering different speed grades has been built; the world's leading Fuxing EMU has been independently developed and successfully realized the commercial operation of 350 km / h China's high-speed rail under the power of science and technology has established its position and benchmarking role in the international competition, and laid a solid foundation for China's high-speed rail to achieve high-quality development in the future.
change the transportation pattern and open up a new era. Many advantages of high-speed rail bring unprecedented space-time effects to China's economic and social development, deeply changing the transportation pattern of our country and creating a new development space for China's passenger and freight transport. The data shows that in the first three quarters of 2019, the national railway cargo delivery volume completed 2.503 billion tons, a year-on-year increase of 6.19%; in 2019, the national railway is expected to complete 3.6 billion passengers, an increase of 92% compared with 2012, and the main indicators of railway transportation rank first in the world. These achievements are due to the unique space-time effect of high-speed rail transportation and the pioneering efforts of China's high-speed rail in construction, operation and management. The development of
high-speed railway in China for more than ten years shows the achievements of China's economic and social development in recent years, ranging from people's travel mode, life concept and activity scope to the national economic strategic pattern, the realization of a well-off society in an all-round way and the great rejuvenation of the Chinese nation, and the high-speed railway has always played the role of a backbone builder. In the future, I believe that on the basis of many achievements, China's high-speed rail will start a new journey from a new starting point, constantly break through and innovate, and constantly serve the country and the people!
