China's high-speed rail: new technology towards the world

China has built the most modern railway network and the most developed high-speed railway network in the world. " At the science and Technology Innovation Conference of China National Railway Group Co., Ltd. (hereinafter referred to as "China Railway Group") held on November 21-22, Lu Dongfu, chairman of China Railway Group, announced that by the end of this year, the national railway business mileage will reach more than 139000 kilometers, including 35000 kilometers of high-speed rail, ranking first in the world. (people's network, December 4)

China has become the country with the fastest development, the most complete system technology, the strongest integration ability, the longest operating mileage, the highest operating speed and the largest scale under construction of high-speed railway in the world. China's high-speed railway is leading the new trend of the world's high-speed railway development. This typical national achievement contains special value of transportation science and technology history, and also breeds science and technology culture with Chinese characteristics.

before, nearly 60 years after the founding of the people's Republic of China, China's railway has been wandering in low speed for a long time. The development of railway is far lower than the speed of economic growth, which has been a bottleneck restricting the development of national economy. Since 2004, great progress has been made. By March 2017, China's railway business mileage exceeded 120000 kilometers, and the high-speed railway business mileage exceeded 20000 kilometers, ranking first in the world. This remarkable achievement has attracted global attention, and the development process of China's high-speed rail has also attracted the eyes of the world. Along the way, China's high-speed rail, from scratch, from weak to strong, from accumulation, introduction and independent innovation, from home to abroad, can be called a world miracle. The brilliance of the history of high-speed rail is illuminating the future of transportation technology.

with the changes of the times, the railway has experienced several ups and downs, but the Chinese railway has always been forging ahead, completing the magnificent turn from "follower" to "leader". People often say: 30 years East River 30 years West River. With the rapid development of China's railway construction, it has made gratifying achievements. The leap from four vertical and four horizontal to eight vertical and eight horizontal, especially under the mode of "public transportation" operation of high-speed rail motor cars, the tourism that lets people say "go" has turned from dream to reality. With advanced technology, safety and reliability, low price and high cost performance, and rich operation experience, the standard of every railway constructed in China shall not lag behind for at least 20 years, and the three advantages of China's high-speed railway are firm and unshakable. The achievements already made will not stop. China Railway is still looking forward to the future. The next stage goal of China's railway is to comprehensively improve the level of scientific and technological innovation in key areas of railway, build a developed and perfect modern railway network, and promote scientific and technological innovation in the field of engineering construction and high-speed railway equipment, so as to ensure the safety of high-speed railway and passenger train, as well as the supply efficiency and quality of high-speed railway transportation.

overcoming difficulties lays the foundation for China's standards, and the struggle of generations of railway people finally makes China's high-speed railway run out of China's speed and create a miracle in China. In the vast land of the motherland, China's high-speed rail is weaving a huge mobile network, rewriting the space-time pattern of the whole Chinese society, and also providing Chinese wisdom to help the development of the world.
