In response to the problems exposed by the accident, the railway system organized and rectified in a timely manner to investigate and eliminate hidden dangers in the entire road.
Q. Why do the investigation reports take time? A. The technical and management issues need to be further analyzed and verified; the next step is to put forward opinions on the definition of responsibility. Due to the specialities of high-speed rail design, construction, operation, and management, the situation is more complicated. The links, areas, and scope involved in the investigation work require a lot of testing and verification. A lot of basic work has been done in the early stage, and important basic data and experimental data have been obtained. However, there are still many problems in technology, management, etc. that need further analysis and verification. The formation of accident investigation reports will still take some time. Next, the accident investigation team will continue to work hard in a scientific, rigorous and conscientious manner. It will do a solid job of investigating and collecting evidence in every aspect and will not miss any doubts. The investigation team will scientifically analyze and identify the technical causes of the accident, and trace the root causes to thoroughly investigate the source problems; thoroughly and thoroughly investigate the management reasons for design and development, testing and appraisal, review permission, on-board use, and transportation organization; Relevant responsibilities of relevant units and personnel are defined in accordance with the law, and opinions on handling are proposed. From the aspects of the legal system, mechanisms, standards and standards, traffic organization, and equipment and facilities, proposals are made to strengthen the safe production of railways and promote the healthy development of China's high-speed rail industry. The progress and results of the investigation on the accident will be announced to the public in a timely manner and consciously accept social supervision. According to Xinhua News Agency official response survey report time has not reached the "limit"
According to the provisions of the SAWS, according to regulations, the incident should be submitted within 60 days of the accident, but the special case can be extended up to 60 days. (Reporter Liu Chunrui) How long does it take to form a report from July 23 onwards? Yesterday, the relevant person in charge of the State Administration of Work Safety stated that for the investigation report, the State Council’s Decree No. 493 had a clear provision. However, it cannot be too absolute. It depends on the specific circumstances of the accident.
According to the introduction, according to the State Council's Decree No. 493, the accident investigation team shall submit an accident investigation report within 60 days from the date of the accident. Under special circumstances, the time limit for submitting the accident investigation report may be extended, but it may be prolonged after the approval of the people's government responsible for accident investigation. The maximum period of time is not more than 60 days. In the case of a particularly serious accident, the people's government responsible for the investigation of the accident shall make a reply within 30 days from the date of receipt of the accident investigation report. In special circumstances, the approval time may be appropriately extended, but the extension period may not exceed 30 days.
Judging from State Council Decree No. 493, the accident investigation team formed the accident investigation report within the specified time.
Who is responsible for handling accidents is divided into several categories? The above-mentioned person in charge pointed out that if he has violated the criminal law, he must be investigated for criminal responsibility.

This should be analyzed in accordance with the responsibility of the person responsible for the accident, and it is closely related to the cause of the accident investigation. There will be no speeding.
Expert opinion "Device defects include signal systems"
A panel member believes that a lightning strike has caused problems in the signal system; the final investigation report needs to summarize five groups. Yesterday, Liu Lianguang, a member of the “7-23†extraordinary accident expert group and North China Electric Power University, stated that the State Council “7-23†Investigation Team The progress of the accident investigation announced on the 20th was only a preliminary result, in which the initial identification of the accident had equipment defects and the causes of the malfunction, so-called equipment defects, including defects in the design of the signal system.
"I am mainly responsible for the electrical system. This system has no problem in itself." Liu Lianguang said that the investigation team set up by the State Council is divided into five groups, including expert groups, management groups, and technical groups, while the expert group has another 12 individuals. Divided into three groups, responsible for electrical, signal, and dispatch. He said that the final investigation results and reports of the accident were summarized by the investigation team according to the five groups.
The investigation team stated that the initial identification of the accident was caused by equipment defects and failures. What does the equipment mean in the end? Professor Liu Lianguang said that there are many so-called devices, including signal systems, control systems, and so on. He affirmed the previous statement made by the investigation group of the State Council and the flaws in the signal system design. "The problem with the signal system, mainly caused by lightning strikes, has an impact on the signal," he stressed.
As early as mid-August, the investigation team of the State Council had initially completed the technical report on the accident and the report of the expert group on the direct cause of the accident. Huang Yi, a spokesperson for the State Administration of Work Safety, once said that through preliminary analysis, the accident revealed that the accident had exposed defects in the design of the signal system, which led to the problems caused by lightning strikes, and also reflected the inadequacy of emergency response and safety management after the occurrence of the malfunction. There are vulnerabilities.
