Have you ever seen the fastest wheel-rail high-speed rail in the world? China is underperforming?
How fast can the fastest train you've ever seen? 350 km/h? Recently, there is good news from an important organization affiliated to CRRC. It has developed the world's fastest train and the world's fastest wheel-rail high-speed rail. Have you seen it? Its speed reached 600 kilometers per hour. This time, the high-speed maglev test prototype was tested. The successful test run on the maglev test line of Tongji University in Shanghai marked an important new breakthrough in the research and development of high-speed maglev in China. However, some netizens commented that China's performance is not good. As expected?

In fact, in order to develop the railway network, the country has started planning and construction very early, and the importance of railways is not inferior to that of national defense construction. After all, railway transmission lines are the main artery of a country's economic transportation, but China has considered the development direction of railway construction in the past. After thinking about rail trains and maglev trains for a long time, the idea of maglev trains was finally abandoned at the beginning, and it was decided to build high-speed rail to develop railway transportation. Why did the country abandon maglev trains in the first place?

The first reason is that maglev train technology was unreliable in the 1990s, and there are few maglev train operating routes for reference abroad. Many new technologies are often not only immature in technology when they are first born, but also very expensive. China The main consideration is these two issues, and China is a country with a vast territory, and the application of new railway technologies must also be large-scale. If a 40,000-kilometer maglev train is built, it will be an astronomical sum for the country at that time. .
In the end, the state decided to build a demonstration line for the trial operation of maglev trains, and built a maglev demonstration operation line from Shanghai to Pudong Airport. All others used rail trains. The earliest high-speed rail built in China was the Qin-Shen Passenger Dedicated Line. Now, after years of development, China's high-speed rail The national layout is basically completed, and the "four vertical and four horizontal" high-speed rail network has been built, but people find that high-speed rail also has limitations. At present, the speed of 350 kilometers per hour is already very fast, and the speed is about to reach the bottleneck. If you want to be faster, you can only use maglev.

Why do you say that the speed of the railroad train has reached a bottleneck? Because China has conducted a test. In 2011, the Harmony train ran at a speed of 487.3 kilometers per hour on the Beijing-Shanghai high-speed railway, but the test found that when the speed of the train was increased to 400 kilometers, the noise level Exceeding the standard, in terms of energy consumption, high-speed rail with a speed of 420 kilometers per hour has a per capita energy consumption of 44% higher than that of trains with a speed of 350 kilometers per hour, which does not meet the requirements of environmental protection, and rail trains need to rely on the track to run, the faster the speed, the better the safety. Much lower.
Today, China's economy still needs to continue to stimulate development, and high-speed rail technology is not static. Although the domestic high-speed rail has already achieved scale, the country is now stronger than before. The previously dismounted maglev train was put on the agenda again. In 2016, China's first medium and low-speed maglev train started operation in Changsha. In 2017, the Beijing S1 maglev train line was opened, and now the domestic 600-kilometer maglev train has also successfully passed the initial test work. , once this kind of train enters people's lives, the impact will be very large.
