The continuous low temperature, rain, snow and freezing weather not only affected the operation of the train, but also increased the difficulty of maintenance work. In the Beijing South EMU, which is responsible for the overhaul of the Beijing-Shanghai and Beijing-Guangzhou high-speed railways, the maintenance personnel have added a new identity - de-icers, who want to make the high-speed rail trains passing through the wind and snow warm into the warehouse and have a safety physical examination.
The continuous snowfall in the past few days has led to the suspension of some trains on the Beijing-Shanghai and Beijing-Guangzhou high-speed railways, but the inspection work of the Beijing South EMU has not decreased, and is still multiplying. Because each train must be de-iced and then tested after being put into storage.
At 11 o'clock in the evening, the C2727 train, which runs for a day between Beijing West and Xiong'an Station, completes the task and is put into storage for maintenance, with thick ice on the front of the train.
Reporter from the main station: If the ice is not removed, what is the impact?
Wang Changlei, the duty director of the first-level repair workshop of the Beijing South EMU Application Institute of the Beijing EMU Depot: There is a TEDS detection system for the running status of the EMU online, if there is ice cover, the specific mechanical parts of the EMU cannot be seen, so after storage, the ice must be removed first.
Wang Changlei told reporters that the ice of the bullet train is like removing ice and snow before we drive after the snow, but it is more difficult, especially the bogie part at the bottom of the vehicle, which has higher technical requirements.
Wang Changlei, duty director of the first-level repair workshop of Beijing South EMU Application Institute of Beijing EMU Depot: The most difficult thing is the connection of the air duct, if you use brute force, it is easy to cause damage to the connection. The tool is rubber, just to protect the mechanical parts under the car, and it must be knocked slowly.
Wang Changlei was also on duty with 20 maintenance workers, relying on the popsicle in their hands, a train down, the fastest half an hour, if you catch the train with thick ice, it will take three hours.
At one o'clock in the morning, another train entered the warehouse. Due to the suspension of nearly 100 trains in Beijing the day before, including many return trains along the Beijing-Shanghai and Beijing-Guangzhou high-speed railways, which originally needed to be overhauled at the destination, they had to be temporarily overhauled here due to snowfall.
Wang Changlei, duty director of the first-class repair workshop of Beijing South EMU Application Institute of Beijing EMU Depot: It is our job to ensure that the EMU is safely and punctually launched and the passengers are delivered safely. Family members take the car, classmates take the car, and say that they are in the car that you overhaul, which is also a kind of pride.
