(Xinhua Viewpoint) Why shouldn't an accident occur?

—— Reasons for a Major Major Railway Traffic Accident on the “7.23” Wenling Line Xinhuanet Wenzhou, July 25th: Nearly 40 people were killed and about 200 were injured—on July 23rd, this was the heart of the Chinese railways. The painful day is also a sad day in the history of China’s railways.

Rear-end! This should be confined to the more common accidents in motor vehicle driving, but it was incredible that it took place in two large-scale, technically advanced trains.

Then, how did this particularly serious rail traffic accident on the “7.23” Wenlin line occur? The lives of passengers cannot be vanished. People sincerely hope that the cause of the accident can be ascertained as soon as possible.

Follow-up question 1: Why does the driving safety system fail?

"I have confidence in the safety of China's motor vehicles, but this time I was puzzled by the rear-end accident!" said Li Lanting, a D301 passenger.

The 40-year-old Li Yanting is from Tianjin. At 8:10 in the morning on July 23rd, her family of five who was going to play in Yandang Mountain, Wenzhou, got a car from Tianjin. There is rain all the way, but the train is still running smoothly, but it often stops.

Before entering the Yongjia station in Wenzhou, the rain was getting louder and louder, and Li Yuting was vaguely worried. She felt that the speed was a bit slow. "The speed is less than 100 kilometers per hour and the train was already 25 minutes late."

The D301 trains did not stop at Yongjia station, but the train stayed here for a few minutes. At 20:24 pm, after getting the starting signal, the train restarted and the speed was significantly faster. "As early as this speed, the train will not be late." Li Yuting said to her family.

At this moment, another D3115 train is not far from the front, and the speed is significantly slower than D301. The distance between the two vehicles is shortening dangerously, but nobody realizes it - whether it is passengers, motorists, or even the rear train control command center...

The passenger net friend “Shi Xi Song” was sitting in the D3115 train 15 cars at the time. Her Weibo recalled that “about 7:50 pm that night the train stopped at Yongjia station. The train insiders told everyone that because of the weather, they had to wait for parking.” At 20:15, the train departed from Yongjia station, but the speed was lower. SLOW.

At 20:38, on the Lancang River Bridge at the foot of Shuangluo Village, Huanglong Street, Lucheng District, Wenzhou City, the D301 train caught up with the vehicle at high speed. The D301 train driver Pan Yiheng, who discovered the danger, took emergency braking measures, but it was too late and the two cars inevitably collided. When the armed police opened the driver’s cabin that had been seriously deformed, Pan Yiheng had already sacrificed and his chest was penetrated by the brakes...

When the rear car D301 bus emergency brake, passenger Li Yuting felt the car kept shaking, and issued a "bang, bang" slowdown sound, with the last loud collision loud noise, all five of their family fell to the ground.

D3115 passenger passengers in front of the car “Shi Xi Song” felt that the train quickly ran forward, roughly gliding for five or six minutes, after which the whole train compartment was dark and the carriage was tilted to the left.

After a fierce rear-end collision, the 13th and 16th trains of D3115 EMU train derailed, the 1st to 5th trains of D301 EMU train derailed, and the 4th carriage fell below the bridge. One carriage was suspended and one was on Gaoqiao. The other end is inserted in the ground like a huge exclamation point! By 15 o'clock on the 25th, the accident had caused 35 deaths and 192 injuries.

According to the common sense of train operation, both the general electric locomotive and the high-end motor car are loaded with safety blocking systems to prevent collisions and rear-end collisions. This system can effectively determine the train speed and locate the location. But this critical vehicle safety system has failed at the most critical moment. What is this?

“According to the normal situation, the train should not have such a rear-end collision, but it just happened...” Wang Yongping, a spokesman for the Ministry of Railways, said in pain: “The State Council has organized an accident investigation team and will seriously, seriously and carefully The cause of the accident was clarified and the Ministry of Railways actively cooperated with the accident investigation."

Follow-up question 2: Is the train dispatch management in place?

In view of safety production experts and railroaders, the train rear-end is a very ridiculous thing, and man-made and management factors can not be ignored.

"Even if the train signal fails, the phone can always communicate? Can you bump it?" Many passengers asked this question.

The trains are large and fast, and the braking distance is at least several kilometers. The distance between high-speed trains is longer and it is impossible to prevent the rear-end train from being visually detected by the driver. In the course of trains, there is not only a set of traffic control systems but, more importantly, the command of the dispatch center.

"Management responsibility cannot be slackened, and any accident that must have destroyed all kinds of constraining principles leads to it." Professor Chen Guoquan, professor and manager of Tsinghua University, stressed the importance of management.

In the particularly serious traffic accident on the Jiaoji railway that occurred on April 28, 2008, the reason why the two trains collided was precisely due to internal management confusion and was a typical liability accident.

"Hay's Law" is a well-known principle in safety production management. Its core essence reminds people that there are signs behind the accident and there are signs behind the signs.

The accident control of the temperature line was controlled by the Shanghai Railway Bureau, and the D301 train from Beijing South to Fuzhou was just opened on July 1 after the railway adjustment, and it took the Beijing-Shanghai high-speed railway line in the Beijing-Shanghai section. “It was really a sigh that we had an accident in less than a month!” said an industry insider who did not want to be named. “In fact, frequent lightning strikes have caused trains to be delayed lately and this should have caused the management department to attach great importance to it.”

Like the prevention of rear-end collision, not to mention the EMU, even if it is an ordinary train, there will be extremely stringent safety operations and dispatching command specifications. Even if a lightning strike causes the signal to fail, the train is ultimately managed by the people. "The car is dead, people are alive."

According to the recall of two passengers, the speed of the front vehicle D3115 was about 20 kilometers while the speed of the rear car D301 was about 100 kilometers. If the schedule is correct and the time difference between the two vehicles leaving Yongjia station is about 10 minutes, the rear car should have enough time to stop. The accident should involve issues such as the signal system and the dispatch management system.

"This is not a natural disaster! There is no sign beforehand. There should be a reason for the loss of control and no coordination." D301 passenger train passenger Liu Yixin said.

On the evening of July 24, the Party Group of the Ministry of Railways decided to retire the director of the Shanghai Railway Bureau Long Jing, the party secretary Li Jia, and the deputy director of the deputy director of the Public Works and Communications Department, He Sheng, of the Shanghai Railway Bureau, who had a particularly serious railroad accident on the “7.23” temperature line. And investigate.

"As a higher-level administrative department, no matter what causes the accident, it should bear the responsibility of leadership." Wang Yongping, a spokesman for the Ministry of Railways, said in a reporter's question. He also said that the "black box" of the motor car has been found. The "black box" is a monitoring system for train operations. It is used to analyze accidents and provide raw data. The current survey of black box data is in progress.

Question 3: Can peace be replaced by blood?

The tragedy is painful and the accident is alarming.

"It is still very confident for China's motor coaches, but we sincerely hope that the relevant departments can learn from the painful lessons of this accident and strengthen safety management, which will not only allow the motorized vehicles to run fast but also do a good job, so that the people can rest assured!" D301 Passenger Coats Li said.

On the 24th, Zhang Dejiang, member of the Political Bureau of the CPC Central Committee and deputy prime minister of the State Council, came to Wenzhou to guide the accident rescue, rehabilitation, and accident investigation. He announced the establishment of an accident investigation team at the State Council. He said that the accident investigation team should carry out accident investigation work in a serious, practical, and scientific manner, identify the cause of the accident, sum up the lessons of the accident, and strictly handle relevant personnel in accordance with laws and regulations.

The responsible person of the Ministry of Railways stated that the nature of the accident was very serious. For this accident, the railway department will conduct in-depth investigations and analysis, identify the reasons, and learn lessons profoundly, and resolutely put an end to the recurrence of similar accidents.

A number of passengers reported that other details of the accident have attracted attention. For example, at present, there are no seat belts in the seats of motor vehicles, and some passengers cause collision injuries. After the accident, the door of the motor car box cannot be opened and the glass is not broken; there is also no life hammer in the carriage. After the passengers flee the train, the two sides of the viaduct track can be used as Escape route, but it is seriously disrepaired, increasing the difficulty of escaping...

Passenger Liu Yixin said that after the train crash, it was hard to find a life-saving hammer, but the three people took turns to smash the glass, but they still could not open it. “I heard later that there were many precautions and techniques in the window, but at that time they panicked. Who would wonder?”

Ms. Sun on the 15th carriage of the D301 car said that if the train should be like an airplane, the flight attendant should first train the passengers on safety as soon as they can get on the train. However, on the train, many flight attendants continue their old train habits and are busy selling. Beverages, poker, books make money.

Wenzhou Kangning Hospital medical staff involved in the rescue said that if there are seat belts in the motor vehicle, casualties can be reduced by more than half, because many victims were thrown off the seat and hit a hard object, caused by head, chest and waist injuries.

This is an accident that should not have occurred. It is distressing and even more alarming that the blood of passengers in distress cannot be allowed to flow.

Minister of Railways Sheng Guangzu said that it will investigate and analyze the cause of the accident, earnestly learn lessons from the accident, and act quickly to boost its spirit. It will take resolute and effective measures, earnestly carry out safety inspection activities, comprehensively investigate and eliminate potential safety hazards, and resolutely prevent new serious accidents from occurring. Rapidly stabilize the transportation security situation. (Reporters Zhang Xudong, Zhu Liyi, Qi Zhongxi, Li Yaxi, and Yue Deliang)
