"Millimetre" must be compared to pave the way for "rejuvenation" of China's high-speed rail

At 8:35 a.m. on October 18, a cr200j "Fuxing" EMU train loaded with 466 passengers slowly started from platform 3 of Kunming station, arrived at Qujing City after 1 hour operation, and Xuanwei City after 1 hour and 50 minutes operation. (people's network, October 19) the

railway is a major artery of national economy, key infrastructure and major livelihood projects. It is the backbone and one of the main modes of transportation in the comprehensive transportation system, and plays an important role in China's economic and social development. For Qujing, the second largest city in Yunnan, and Xuanwei, a populous county, the "Fuxing" with high beauty, strong comfort, good stability and high intelligence will further enhance the ride experience of the people in Northeast Yunnan, improve the travel mode of the people, and make the life of the people along the line more colorful. In recent years, with the development of China's standardized EMUs and the realization of complete independence of core components, China's high-speed rail has become a more beautiful diplomatic card, with no bad security at all except for its leading technology. I still remember that a few days ago, the video of a coin standing on the fast-moving high-speed railway exploded all major media at home and abroad, which made people have a deeper recognition of the safety and stability of China's high-speed railway operation. So what's the secret of keeping coins standing on high-speed trains? The

track guides the train forward, and two parallel rails are an important part of the track. With smooth rails, the harmony and Renaissance will run a magnificent landscape in the vast land. Rail has also become the cornerstone of the train moving in all directions. When the rail carries the train, it is destined to shoulder the responsibility of the stable and safe operation of the train and the safe and comfortable arrival of passengers to the destination. Therefore, the solid foundation stone is the key to the smooth and high-speed operation of high-speed railway, and also the magic weapon to win the passenger comfort!

although the "Fuxing" from Kunming to Qujing and Xuanwei is not as fast and stable as we think the speed of the new line is 350 kilometers per hour, as the upgrading and reconstruction of the Shanghai Kunming Railway (Yunnan section), Qujing section of Kunming Railway Bureau Group Co., Ltd. of China Railway, in conjunction with relevant units, organized a thousand people's congress battle to give full play to the "potential" of the existing line. According to the maintenance standard of "high-speed railway", the grinding error is firmly controlled within plus or minus 0.3mm, and the gauge level is controlled within plus or minus 0.5mm. Through unremitting intensive cultivation, a high-quality and smooth "high-speed" intercity railway for "Fuxing" has been successfully built, which makes the legend of "coins do not fall" amazing again. A 6031 a 6031 the so-called difference is a millimetre, a thousand miles away. Perhaps, a few millimeters is very small, especially for a kilometer long 100 ton rail, so small that you will not notice what impact these millimeters will have on the high-speed rail, that is to say, a small point will affect the ride comfort, that a large point will directly affect the driving safety, if not eliminated in time, it may even lead to serious safety accidents. A 6031 a 6031 a powerful transportation country, railway first. The author believes that there is a legend of "coins do not fall" behind the launch of "Fuxing" every time, which is a reflection of the mission and responsibility of countless railway people. They stick to the Wanli railway line day and night, use the patience of embroidery to "check the pulse" for the train patrol, and firmly adhere to the belief of "stick to the right way, i-guard safety", so that countless railway lines can firmly embrace the "Fuxing" and then Let more high-speed trains representing the world's advanced level run on the vast land of the motherland.
