More than a hundred experts "put pulse" high-speed rail safety

On August 15th, the State Council High-speed Railway and the mobilization and deployment meeting for the safety inspections of its projects under construction were held in Beijing. 175 experts will participate in the high-speed rail safety inspection. Experts are required to give full play to their advantages and roles, so that “both medical treatment and prescribing” can be done to improve the scientific and remedial targeting of safety hazard investigations.

High-speed rail "medical examination"

Since the Shanghai-Hangzhou High-speed Railway opened in 2010, the train from the end of the evening to the next morning, the integrated test vehicle for detecting the safety of the line will become the "protagonist" on the track. These comprehensive test vehicles are like the doctors treating high-speed railways. They automatically detect and record all the indicators of the railway line while running. The maintenance workers will use these indicators as the basis for line maintenance. Such "medical examinations" are just daily routines.

In order to systematically investigate and completely rectify the hidden dangers of high-speed railways, and effectively prevent and resolutely curb the occurrence of serious and serious railway traffic accidents, the General Office of the State Council issued the “Circular on Launching the High-speed Railway Safety Inspection” on August 12.

The scope of this inspection includes high-speed railways and projects under construction (including passenger dedicated lines) operating at speeds of 200 km/h and above, which will start from mid-August to mid-September. If there are serious security risks, they will be ordered to stop or stop production immediately.

12 related technical experts from 12 ministries and commissions, and 12 inspection teams will serve as “high-speed rail doctors” for 10 railway bureaus and equipment manufacturers in Beijing, Shanghai, Guangzhou, etc., to investigate the cause of disease, to open a good party, to conduct unannounced visits, and conduct spot checks. Census, in-depth site, access to information, investigation of hidden dangers, the safety of a good high-speed rail.

Fang Jun, a media commentator, believes that “to carry out safety inspections is to allow the people to ride the 'safety high-speed train' and need to focus on the nation’s experts and intelligence, and come up with a comprehensive 'consultation’ for high-speed rail safety, and give a practical and realistic assessment. Only in this way can the people be assured.”

Safety "make up"

“The high-speed rail is the speed reduction. To ensure the safety of passengers, it doesn't matter if you are slower. It is also possible to reduce the price of the fare after the speed has been reduced. It can be described as a double benefit,” said Mr. Zhang, who is engaged in clothing trade in Shanghai.

The July 23 accident sounded the alarm for high-speed rail safety. After the accident, China’s high-speed rail experienced a series of “curing the disease” process such as recalling, adjusting maps, decelerating, and cutting prices.

On August 11th, the China North Locomotive and Rolling Stock Industry Corporation announced that it will recall 54 CRH380BL EMUs operated by its subsidiaries and operating on the Beijing-Shanghai high-speed rail. The EMUs were used in 36 groups on the Beijing-Shanghai high-speed rail, which accounted for 42% of the 300 km/h EMU of Beijing-Shanghai high-speed rail. CNR said that it will systematically analyze the causes of the failure and comprehensively rectify it to ensure the quality of the source. This is also the first time in the history of China's railway recalled.

The recall of motor vehicles gradually started the adjustment of China's high-speed rail. At 0:00 on the 16th, the Chinese railway began to implement a new train operation map. The new map reduced the speed of some of the high-speed rails; the fare for each seat was 5% lower than the current fare level. This adjustment is also the first time that China has slowed the pace of high-speed rails after six consecutive railway speed increases in the past ten years and repeatedly hit the highest speed of high-speed rails, seeking the simultaneous development of speed and safety.

According to the Ministry of Railways, the four high-speed rail lines (Beijing-Shanghai high-speed rail, Beijing-Tianjin inter-city, Hainan East ring, Guangzhou-Guangzhou intercity) involved in the first phase of the railway map adjustment are full of tourists and order is good. As of 15 o'clock on the 16th, the punctuality rate of more than 240 EMUs reached 100%.

“This is a 'remedial class' for China’s high-speed rail after the “7.23′′ special temperature rail accident on the Dongfeng Line,” said Minister of Railways Sheng Guangzu.

Construction slowdown The pace of China’s high-speed railway construction has slowed down. The domestic high-speed rail industry has entered the period of rectification from a period of rapid development, but the high-speed rail will further develop, and safety assessment is the key.

The Standing Committee of the State Council proposed on August 10th that the railway construction projects that have been approved but not yet started should be reorganized for the safety evaluation of the system; the new railway construction projects should be suspended for approval, and the accepted projects should be further demonstrated and the technology of the projects should be reasonably determined. Standards and construction programs.

According to the plan, by 2020, China will build more than 16,000 kilometers of passenger dedicated lines, including four vertical and four horizontal rail lines. Earlier this year, the Ministry of Railways stated that in 2011, a total of 4,715 kilometers of high-speed rail lines, including Beijing-Shanghai, Harbin, and Beijing-Beijing, will be built and put into operation. However, the time has already passed half of the time. Only the Beijing-Shanghai high-speed railway is in operation. Hanyi and Guangzhou-Shenzhen are still open to traffic this year, while nearly 3000 kilometers of high-speed rail such as Ha Da, Jing Shi and Shi Wu are expected to be postponed until 2012. Years, and even 2013, can be opened and operated, accounting for more than 60% of the total.

Prof. Han Baoming from the School of Transportation and Communication at Beijing Jiaotong University stated that the adjustments after the high-speed rail will be in line with the market demand and ultimately achieve a win-win situation for both the company and the passengers. In addition, it is necessary to carry out a comprehensive inspection of some equipment in vehicles and lines, and in constant inspection and adjustment to ensure the safe operation of trains. For the current high-speed rail in China, it is particularly important for passengers to regain confidence.
