High speed rail coins show the hard power of China's high speed rail

The reporter experienced a "world-class" stability on the 350km high-speed railway of Zhengzhou and Fuyang. TQI is the key factor affecting the safe operation of the train. Compared with the Beijing Shanghai high-speed railway, Zhengfu high-speed railway is more stable and TQI is controlled below 1.8. The CRTs Ⅲ slab ballastless track structure with independent intellectual property rights in China is adopted to realize the fine assembly of the factory system. (Sina Weibo) a 6031 a 6031 netizen joked that it must be because high-speed railway engineers are carsick that they have designed such a stable train. The author believes that whether it is true or not, it is certainly a good news for passengers and a demonstration of the hard power of China's high-speed rail. By the end of 2018, China's railway business mileage has exceeded 130000 kilometers, including 30000 kilometers of high-speed rail, more than two-thirds of the total mileage of the world's high-speed rail, becoming the only country in the world with high-speed rail network operation. There is no doubt that China has become the country with the strongest integration ability, the longest operation mileage, the highest operation speed and the largest scale under construction in the world. China's high-speed rail diplomacy, the name card of high-speed rail, is also increasingly dazzling. A 6031 a 6031 is a high-speed railway running at a high speed of 350km / h, among which passengers are walking on the ground. Passengers on the train can not only walk around at will, but also eat and drink water. The passenger experience has made a qualitative leap. It's so beautiful that they arrive at their destination unconsciously after eating, chasing drama and sleeping!

why is a high-speed train so smooth? This is mainly due to the track and control system of China's high-speed rail. On the one hand, the curve of ballastless track has large radius and high smoothness, which reduces the vertical and horizontal vibration. On the other hand, China's high-speed rail has a strict control system for train acceleration, which ensures the longitudinal stability of the train during operation. Strict vertical, horizontal and vertical control has made China's high-speed rail the most stable high-speed rail in the world. Lu Guanren, senior engineer of the Ministry of public works of China Railway Jinan Bureau Group Co., Ltd., summed up in five words: stable, smooth, level, inspection and repair. With the improvement of railway people, the smoothness of high-speed railway has reached the advanced level in the world. So when you take the high-speed rail, walking in the car with a speed of 350 kilometers per hour is like walking in a idle yard. Only then can there be the myth that "the tree coins on the high-speed rail will not fall". A 6031 a 6031 is a powerful transportation country, and railway takes the lead. In the research report issued by the world bank, China's high-speed rail is fully affirmed, and the development experience of China's high-speed rail is worth learning from other countries. At the same time, China's high-speed rail has already won high recognition from the international community with its amazing development speed and excellent strength. The dividend brought by the rapid development of high-speed rail is being released step by step. The future of China's high-speed rail is promising!
