It's a good idea to let the fast high-speed trains "slow".

After more than ten years of rapid development, China Railway will decelerate for the first time. Premier Wen Jiabao presided over the executive meeting of the State Council today and decided to carry out major safety inspections on high-speed railways and their projects under construction, appropriately reduce the initial speed of the construction of new high-speed railways, and re-organize the safety assessment of the proposed railway projects.

It took less than 10 years for China to build the world's largest high-speed rail network and occupy a place in the international high-speed train market. This made the officials and engineers of the Ministry of Railways of China proud and made the Chinese people proud. However, the train crash that occurred last month has greatly reduced this national pride, followed by extensive criticism and suspicion.

The development process of China's high-speed rail is a process of introduction, digestion, and improvement. It needs time to combine various technologies, test signals and management systems, and to build high-quality infrastructure and supporting equipment. However, in just 10 years, the high-speed trains built in China have miraculously reached more than 5,000 kilometers, ranking first in the world. The so-called radish is not washing mud soon, and it is unavoidable that some problems appear in the Chinese high-speed rail that has been criticized as “going fast”. From the construction of a huge amount of high-speed rail projects and the large and complex technical systems of high-speed railways, it is impossibly impossible to complete every project and every technical detail. What's more, it also involves the corruption of individual important officials and the possible negative impact on the railway construction.

In fact, some experts at home and abroad have long questioned that China’s high-speed rail has developed rapidly over the past few years, and that it has reached the world-class level in its own innovation and operating speed, which is achieved by eating the safety redundancy in the original design.

According to remarks made by Zhou Yumin, deputy director of the Ministry of Railways’ high-speed office, in the domestic media, the speed of 350-380 kilometers per hour implemented by other domestic high-speed rail lines was a “fake” irrespective of the safety factor. It is the purpose of Liu Zhijun, the former Minister of Railways, whose reputation is now disappointed. .

Some experts here also believe that China’s economic development has always emphasized speed and is no exception in the construction of high-speed railways. It is hoped that in the short term, “the world’s first” will be achieved, and even the opening time of high-speed railways must be coordinated with a large-scale event. Driven by vanity, speed is often exchanged for stability and reliability, which inevitably causes hidden dangers for the accident.

Until the former railway minister Liu Zhijun stepped down and the new Minister Sheng Guangzu came to power, the state of development of China’s high-speed rail that is on the verge of losing control has changed. When Sheng Guangzu came to power, he considered that the speed of development of China’s railways and the speed at which high-speed rails operate too quickly should be reduced. In June, it ordered that some high-speed rail lines be decelerated appropriately. This move was then appreciated by many people with lofty ideals. Wang Ming, president of the "Financial Times" Tokyo Branch, published an article on "China's high-speed trains slow down very wisely" on July 1, affirming Sheng Guangzu's move.

According to insiders, there was a great objection to the deceleration of high-speed rail operation within the railway system at that time, saying that it was contrary to the pursuit of an efficient and rapid modern lifestyle. It was not until the July 23 accident that consensus was quickly formed. Only then has there been a major policy measure introduced at the State Council level for the high-speed rails to reduce prices.

It is reported that after lowering the operating speed, the design of a high-speed rail with a maximum speed of 350 kilometers per hour will be operated at a speed of 300 kilometers per hour; a high-speed rail with a design speed of 250 kilometers per hour will operate at a speed of 200 kilometers per hour. For speed-reducing trains, the fares will also be reduced appropriately.

However, as soon as this policy measure was introduced, it was also questioned: When a car running 300 kilometers on a 350-kilometre track is not directly proportional to investment, is it a huge waste of technology and investment?

According to estimates by experts, the operating costs of railways are directly proportional to the operating speed. The increase in operating speed will greatly increase operating costs. When the speed of the high-speed rail exceeds 270 km/h, more than 90% of the traction force is used to overcome the air resistance. When the speed of the high-speed rail exceeds 300 km/hour, more than 95% of the traction is used to overcome the air resistance. When the vehicle speed exceeds 300 km/h, wheel idling occurs, resulting in power consumption and accelerated wear. In other words, the faster the high-speed trains operate, the more energy and equipment are depreciated, resulting in higher operating costs and correspondingly higher fares. Therefore, this question basically does not hold.

According to most opinions, the deceleration of the China High Speed ​​Rail is mainly considered from the perspective of security. As the "Beijing News" editorial said, the high-speed rail that people need is a safe high-speed rail, a high-speed rail that can afford to use, and a high-speed rail that receives quality service. The lack of safety and security of high-speed rail, the faster the speed, the higher the risk factor. With such a high-speed train, even the lives of the family can not be guaranteed. Who will applaud it?

In addition, from the perspective of exploring the international market, China's high-speed rail has achieved a good record of safe operation in China and is the best basis for future success in overseas.

It can thus be seen that China’s letting the fast-tracked high-speed rail decelerate is a good measure.

China needs a high-speed rail to get the railroads up quickly. It is the trend of the times and people's expectations. The Chinese government complies with the people's minds and unswervingly continues to develop high-speed railways. It adheres to scientific planning, overall coordination, and adheres to a century-long plan and quality first. It is determined to effectively build each project into a quality project, truly making China's high-speed railway a reality for the entire country. People are assured of the railway.

We have reason to believe that: After China's high-speed rail reborn through its own nirvana, it will surely bring people's expectations and satisfaction to run on the track of happiness and drive in the beautiful "spring."
