According to the operation and management center of Shanghai Shentong Metro Group Co., Ltd., at about 10:20 a.m. on November 12, the section from Lianhua Road to Shanghai South Railway Station on Line 1 suddenly tripped through the catenary, accompanied by abnormal noises and smoke. The operator quickly activated the emergency plan and is currently actively disposing of it. As of 13:06, the power supply fault of Line 1 has been eliminated and the line operation has returned to normal.
Mr. Lu told the Red Star News reporter that he took Line 1 to work this morning and did not expect to experience the incident. According to him, when the subway was running between Jinjiang Amusement Park and Shanghai South Railway Station, he stood at the front of the car against the door position, "Suddenly there was a sound of suspected impact, the car lights suddenly went out, the vehicle started for the second time, and then 'boom' stopped, when the people behind the carriage ran to the front of the car, probably afraid." ”
The passenger said that at that time, the subway staff calmed the passengers' emotions through the radio, and after about 50 minutes, the passengers obeyed the arrangement to get off through the cab door in an orderly manner, and then withdrew from the tunnel, "I probably walked for a few minutes to get out of the subway station, and at that time, the cordon was pulled up to prevent the passengers from Getting off and off from Shanghai South Railway Station, so I transferred to other lines to go to work." ”
At the same time, a passenger on another train on Line 1 told the Red Star News reporter that at about 10 o'clock in the morning, when the subway ran to Xujiahui, all members were suddenly notified to get off, and then the station broadcast said that the temporary fault at Shanghai South Railway Station was delayed by twenty minutes, and then it became ten minutes late, "I thought it was almost good, I waited at the platform, and as a result, I kept reporting several "ten minutes late", and then another broadcast said that I took a short shuttle bus from Exit 14, and then I went out." The passenger said that due to the accumulation of many passengers inside the station, after everyone crowded out of the ground, the scene was very chaotic, waiting for many cars to get on the short barge, "from getting off the bus to taking the short barge took an hour."
According to the operation management center of Shanghai Shentong Metro Group Co., Ltd., after the accident, passengers affected by the failure of Line 1 can obtain an apology letter through the operation page of the official website of the Shanghai Metro, which said, "On November 12, 2021, due to the failure of rail transit equipment, the train operation was delayed, which caused inconvenience to your travel, please understand." We apologize to you and thank you for your cooperation. ”
The Red Star News reporter noted that three months ago, Shanghai Metro Line 1 had a speed limit in some sections due to line equipment failure. According to the news released by the operation and management center of Shanghai Shentong Metro Group Co., Ltd. on August 10, "the train from Gongfu Xincun to Fujin Road section is limited to speed, the departure interval is extended, and it is expected to be delayed by more than 15 minutes. ”
A power industry practitioner told Red Star News that the catenary trip in the subway is similar to the circuit circuit in the home electricity, which can be caused by a variety of reasons, such as equipment problems, line aging, external force damage, etc. "The power required for subway operation is very large, and the sudden frustration of suddenly stopping after the power outage will be relatively strong, and within one or two seconds, the lights will also be extinguished." ”
As a public transportation vehicle, the impact of the subway after the failure is not small, the above-mentioned power industry practitioners said that the subway maintenance personnel should pay attention to daily inspection and maintenance, the relevant equipment within a certain time frame, according to the standard provisions of the replacement, and regular maintenance, to avoid such a situation.
