Wenzhou train rear-end accident management problem was confirmed delayed troubleshooting

58 stations are still using the same type of signal equipment. "Lightning strikes destroyed the equipment, and the equipment on the train control line was broken down." The above-mentioned sources told this reporter that the factors of natural disasters were an important factor in the disaster.

He said that the weather on that day was also very special. There were more than 100 lightning strikes in 7 minutes and it was rare in Wenzhou. "If there is not such a big lightning strike, equipment can be used. More than 50 stations are still in use," he said.

According to public reports, at the first plenary session of the investigation team of the “7 23′′ special severe railway traffic accident group held in Wenzhou on July 28, Peng Kaizhou, deputy director of the Ministry of Railways, said that the National Railway and Wenzhou South Station use similar signal equipment. There are 58 stations and 18 base stations.

The signal equipment that suffered a lightning strike failure experienced a simulation test by the investigation team. However, lightning damage to equipment does not directly lead to rear-end trains. Peng Qiyuan, dean of Southwest Jiaotong University’s School of Transportation and Communications, told this reporter that such equipment follows the “fault-oriented security” principle. “If the equipment is damaged, it should be oriented to parking. This should be the case in any failure situation.”

In the "7 23" accident, this principle failed to work.

Management responsibilities can not escape the investigation group told this reporter, the railway system still has management problems, station attendants, electric services are all responsibility, should stop the car repair, but it is trimming open, have not had time to repair There is a problem.

On August 25, when Huang Yi, spokesman for the State Administration of Work Safety, received an exclusive interview with the media, he explicitly pointed out the responsibilities of Wenzhou South Railway Station's telecommunications. "The signal system had problems at that time and it was not normally displayed. However, the personnel on duty at the Wenzhou South Railway Station did not report in time according to the relevant regulations, and did not perform troubleshooting, which did not effectively prevent accidents."

This statement led to a strong rebound in the staff of the electric service. They issued an open letter stating that "no fault handling" was inconsistent with the fact that the on-duty personnel were troubleshooting according to the faults of the two track circuit sections registered for the vehicle. However, "not reporting promptly according to the regulations" is a confusion of duties. In addition, "the Shanghai Railway Administration did not find a fault signal on the road map, and the screen did not show a failure." It was also unfair.

Huang Yi said on August 22 that it will determine the nature and causes of the accident and then confirm the direct responsibility, indirect responsibility, and leadership responsibility of the accident. At present, the official has not yet publicized the identification and division of responsibility.
