Former Minister of Railways: China is temporarily unable to develop a high-speed railway at 500 kilometers per hour

At the 2019 International Engineering Technology Development Strategy High-end Forum held in Jinan, Shandong, December 21, 2019, Economic Observation Network reporter Fu Zhihuan, an academician of the Chinese Academy of Engineering and a former minister of the Ministry of Railways, said that China is developing a high-speed train system at 400 kilometers per hour Research on key technologies of magnetic levitation and low-vacuum high-speed trains. However, it is not yet possible to develop a high-speed train at a speed of 500 kilometers per hour.

Fu Zhihuan is one of the pioneers of China’s electric locomotive industry, and one of the main promoters and decision-makers of China’s railway speed-up. He was once Minister of Railways of the People’s Republic of China. Fu Zhihuan recounted the changes of the Chinese railway he experienced. Fu Zhihuan recalled, “When I was young, I often climbed the windows by train, and also climbed down from the windows to go to the toilet because there were still five or six people standing in the toilet.”

Later, Fu Zhihuan entered the railway system and became the first team member to develop Chinese electric vehicles. Experience shows that the core technology cannot be exchanged for the market, and expectations “standing on the shoulders of giants” are sometimes unreliable. In this regard, Fu Zhihuan has personal experience. In the beginning, he was a member of the first team to develop Chinese electric locomotives. According to the drawings provided by the Soviet Union, China began to manufacture electric locomotives. However, less than half of the Soviet experts were removed. “We thought we were standing on the shoulders of the big brother of the Soviet Union and standing very high, but as soon as people left, we became a dwarf. It was only after ten years of hard work that we developed China’s own power technology.”

Decades later, China’s railway transportation technology has undergone dramatic changes. The operating mileage of Chinese railways ranks second in the world, of which high-speed railway mileage accounts for two-thirds of the world.

In the future, a new round of technological revolution is reshaping the global economy and transportation. The Internet, big data, new materials, and new energy applications are making major breakthroughs. The continuous emergence of new models and new business formats is leading to major changes in transportation. Fu Zhihuan pointed out: What is the goal of building a transportation power? Is to build a safe, convenient, efficient and green modern integrated transportation system. China’s transportation is facing new development opportunities and challenges. To build a strong transportation country, we must not compare ourselves with ourselves. We must have a global perspective.

On the one hand, China is making breakthroughs in original innovation in core technologies from 0 to 1, such as civil aircraft engines; on the other hand, it must also maintain a leading position in some technical fields.

Academician Fu Zhihuan revealed that China is developing a high-speed train system with a speed of 400 kilometers per hour; research on key technologies of magnetic levitation and low-vacuum high-speed trains is being carried out. But for some people asking whether China can get on the 500 km / h high-speed rail, Fu Zhihuan said, “My answer is ‘No’. Not that it is not possible in the test, but that it has problems in its use, because the energy consumption of high-speed trains and Speed ​​squared is directly proportional to the impact of high-speed trains on environmental noise is proportional to the sixth power of speed. If we want to solve these problems, we still have a lot of work to do.
