Five minutes to cross the century-old China Railway, what hardships have we experienced in railway technology?

Recently, a video of People's Daily became popular on the Internet. What's the name of this video? Five minutes to cross a century of China railway? . After watching this video, many people feel very excited and excited. The progress of China Railway is the result of our down-to-earth work.

The first railway

1990, the first railway independently developed and designed by China People and operated by China? Beijing-Zhangjiakou Railway? Officially opened. He was designed by Zhan Tianyou, a famous designer in China. It connects Fengtai in Beijing, passes Badaling and Juyongguan, and reaches Zhangjiakou in Hebei. Because it is the first time that China has independently developed and built a railway, the railway project is arduous. Now it is called Beijing-Baotou Railway, and the former Beijing-Zhangjiakou section was the first railway line from Beijing to Baotou. A year after the founding of New China, many railways were rescued. The first railway built in New China is chengdu-chongqing railway, a railway connecting Chengdu and Chongqing. The east-west direction of the line is very difficult to construct.

Six speed increases

After 1997, Beijing-Harbin, Beijing-Shanghai and other trunk lines will be speeded up by 200 kilometers, some conditional sections will run at a speed of 250 kilometers per hour, and the mileage of the 200-kilometer-per-hour speeded-up line will be extended by 6003 kilometers at a time. These changes indicate that China Railway has accelerated into the ranks of advanced railways in the world.

China high-speed rail

After 2003, after the China Railway speeded up six times, China started the operation of EMU in China for the first time, and began to set up EMU trains with a speed of 200 kilometers per hour in some parts of the country. China railway began to enter the era of high speed.

China railway high-speed is a high-speed EMU technology introduced by China from German and Japanese countries. It not only means the improvement of China railway speed, but also means? Harmony? It marks China Railway's understanding of the concept of Harmony. Is it? Harmony? EMU train, or the name of high-power locomotive, or? The sixth big speed increase, the pursuit of harmony? This declaration shows and maintains the unremitting efforts of railway people to build a harmonious journey, the change and development of railways, the construction of harmonious railways and the good wishes of a harmonious socialist society. It will take some time for the capacity of the new line to form, so we will continue to work hard, continue to optimize our high-speed rail and get more China creations!

Once? Made in China? It's already today? China created it? . China has made great efforts in most aspects of heavy industry and light industry, perfected the construction technology of heavy industry and light industry, and made the high-speed rail network cover the whole country, running through the east, west, north and south. In the future, the traffic in China will be more convenient, which is the speed of China!
