What is maglev technology? Compared with the high-speed rail, what is the difference between it and can it replace the high-speed rail?

Now China is investing heavily in high-speed rail construction. In addition to building more lines, it is also developing more advanced train technologies. For example, some time ago, China released a prototype of a new generation of maglev high-speed rail trains, claiming that its running speed can reach 600 kilometers per hour. Hourly or even faster, so what is maglev technology? How is it different from the current high-speed rail? Can it replace high-speed rail in the future? After the results were exposed, many foreign experts sighed: China is too smart. In fact, the maglev high-speed rail technology uses the principle of magnets of the same sex to repel and attract each other, so that the whole train is suspended on the track without direct contact with the track, which greatly reduces the operation of the high-speed rail. Therefore, it can achieve such a fast running speed, and once this technology is mature, China can build a faster high-speed rail line.

In fact, maglev train technology is not a new technology that has emerged in recent years. As early as the 1990s, this technology has been valued by various countries, and many countries have carried out research and development on it. China is no exception. The world’s first commercial maglev train line was built in Shanghai, and it has been running continuously for nearly 20 years. However, because the technology is too complicated and the construction cost is too high, China has not built a new maglev train line since then. China’s high-speed rail still uses traditional wheeled train technology, relying on wheels to travel at high speed on the track.
However, after China’s Fuxing high-speed railway has reached a high speed of 350 kilometers per hour, the development of traditional high-speed railways has encountered obstacles. Although it is theoretically possible to build faster high-speed railways, after exceeding the threshold of 400 kilometers per hour, traditional wheeled It is difficult to increase the speed of high-speed rail, and the energy consumption required for high-speed operation will also increase greatly, and the cost-effectiveness ratio will be lower than that of the 350 km/h Fuxing. If you want to build a faster high-speed train, you must Use magnetic levitation technology.

After the completion of the construction of the Shanghai maglev line, China has not given up on the research and development of the maglev high-speed rail. Some time ago, China exhibited the world’s most advanced maglev train prototype. It is said that its running speed can reach 600 kilometers per hour, and the fastest speed is 800 kilometers per hour, almost as fast as a passenger plane flying in the air, and according to Chinese experts, the technology of this maglev train prototype has been perfected, and it has completed the operation test on the maglev track, about two or three more time. The technology will be fully mature in 2019 and can be put into operation. At that time, China can use it to build an ultra-high-speed maglev train line with a speed of 600 kilometers per hour, breaking the new limit of the global high-speed rail speed.
