From chasing to leading: the new era and great achievement of Chinese Railway

At the science and Technology Innovation Conference of China National Railway Group Co., Ltd. held yesterday (22), the head of China National Railway Group said that China's high-speed railway, heavy-duty railway and plateau high and cold railway technology have reached the world's leading level, and some key areas have entered the leading stage. (November 23, CCTV) when it comes to the railway in China, you will surely think of "Fuxing", the "eight vertical and eight horizontal", and many achievements of China's high-speed railway Behind these achievements is the high-speed development of China's railway technology from pursuing to leading, witnessing the glorious mission of China's railway, and foreshadowing the new era and great achievements of China's railway.

China's high-speed rail technology, from pursuit to leading, has condensed the hard work of several generations of Chinese people, representing the crystallization of Chinese labor wisdom. When China's high-speed railway started, it had no experience and technology, so it could only imitate and improve the core technology of other countries and introduce a large amount of core technology. But Chinese scientists and engineers who are not willing to do so, under the strong support of the state for the development of high-speed rail, have, after years of hard work, bought their own high-speed rail. On this basis, China's high-speed railway has maintained a good momentum of development, especially in terms of funds, policies, talents, etc., continuously increased independent research and development, formed a good industrial pattern, trained a number of mature technology research and development teams, and accumulated a lot of railway operation and management experience. Taking the new generation of Fuxing as an example, the new generation of Fuxing will deepen the technological breakthrough of system integration, automatic control, energy consumption control, noise control, lightweight, etc., so as to make it safer, more environmentally friendly, more energy-saving and more comfortable. It is of great significance to continuously expand the leading edge of China's high-speed rail technology and accelerate the development of Fuxing series EMUs.

if the development achievements of China's high-speed rail speed up the current economic and social development of China, then the development of China's heavy haul railway technology will create a good transportation environment for China's future and the world's development. The conference introduces that China's heavy haul railway technology has reached the world's leading level, and has built a heavy haul railway technology system covering different axle load grades. The representative is Daqin Railway, which generally operates 20000 tons of heavy haul combined trains, completes the operation test of 30000 tons of heavy haul combined trains, and the highest annual traffic volume has exceeded 450 million tons, becoming the world's largest heavy haul line in the last year. Railway is different from other modes of transportation, one of its biggest highlights is its heavy load capacity. In the future, the transportation of bulk goods will become an important fulcrum of economic and social development. Relying on multimodal transport to carry out the world trade of bulk goods has a broad prospect. These economic activities need to be based on the effective improvement of the capacity of heavy haul railway. China's heavy haul railway has reached the world's leading level, which undoubtedly lays a solid foundation for adapting to the development of this important trend. In addition, China has become the second largest economy in the world. Economic development has an important impact on the development of the world. The development of Heavy Haul Railway Technology in China is also of great significance to other countries in the world. The future development of

Chinese railway is full of opportunities and challenges. On the basis of a series of major achievements from chasing to leading, I believe that China Railway will continue to achieve self breakthrough, achieve better and faster development, bravely take on the major role of railway in the new era, and better serve the country and the people.
