In Yangcheng in August, the heat was unbearable, and the temperature was as high as 35°C. After a few steps outdoors, the whole body was soaked. But in the workshop of Guangzhou Railway Group's Guangzhou Depot, there is such a group of people who climb the roof, drill the stock road, and patrol the carriages. Under the scorching sun, they are sweating and performing vehicle maintenance operations. , Silently guarding the safety of the train. For them, the temperature in August is 50°C, 60°C, and 70°C.

50℃ is the engine room of diesel generator car after long-term operation. Li Yubin and his workers in the generator car class are intensively moving materials and tools to the car, and several large boxes of mineral water are also being carried on the car together. At a high temperature of nearly 50°C, even if you don't do anything, just stand there and get soaked in a few minutes. Diesel generator cars are responsible for the power supply of all electrical equipment in the train. If the maintenance takes too long, it will affect the subsequent test and inspection of train air conditioning and electrical equipment. Li Yubin and his workers must complete the maintenance of three diesel generator sets within an hour. They need to replace the 150L diesel engine lubricating oil and 18 different specifications of fuel filter and oil filter. In addition to this, it is necessary to repeatedly check and test the oil circuit, water circuit, and generator to ensure that the equipment is in good technical condition.
Working at a high temperature of 50°C is like a super sauna. Sweat drips down the clothes and trousers. Li Yubin takes out mineral water from time to time and pours it down. "This kind of big bottle of mineral water, you need to drink two bottles to be comfortable." He told reporters, "We have to drink 3-4 boxes of water after an overhaul of our generator class."
60°C is the heat wave from the brake disc of the train. Liu Wenjie of the inspection class put his face close, stared at the brakes intently, inspected carefully, and tapped the parts with the inspection hammer from time to time. The sound and feel of the knocking were important basis for him to judge the status of the parts. The rising heat wave made his face red, and the beans were so big that sweat beads could not stop slipping off, and there was a large wet spot under his feet. "You have to get close enough to check the smallest problems." While checking the status of the train with his waist, he told reporters, "The brake discs are worn out by a few millimeters, which will affect driving safety, which can be sloppy. No." Every train Liu Wenjie had to walk 5-6 times in the trench and the train back and forth, walking tens of thousands of steps to complete the inspection and test items.

In the hot summer days, there are many inspectors like Liu Wenjie in the inspection class who stick to their posts. They go back and forth in the scorching sun every day, walking nearly ten kilometers. The ditch was hot and humid, and the train that had just entered the warehouse seemed to have been running for a whole day. The heat waves on the face repeatedly evaporated the sweat, leaving circles of white salt stains on the work clothes. In the hot sun, the old masters often made their arms red and peeling from the sun. Until recent years, young people in the day inspection class discovered that ice sleeves can effectively prevent sunburn, so ice sleeves have become standard equipment for the masters. Young people such as Liu Wenjie have also learned the habit of drinking hot tea by the masters of the inspection class. For inspectors who work in outdoor high-temperature environments for a long time, warm tea water can cool off the heat better than iced soda. Quench thirst.
70℃ is the train ceiling after a whole day of exposure. Luo Chunliang from Kuriban wore thick work leather shoes, and could still clearly feel the temperature of the hot feet coming from the soles. The ceiling was too hot to sit on, so Luo Chunliang squatted and used a multimeter to measure one by one. Because his fingers were not flexible enough while wearing gloves, he took off his gloves and left his fingers to fix the problem as soon as possible to ensure that the train can leave the warehouse on time. It was hot and flushed, but it didn't slow down the work progress at all.
Summer is hot and hot. The operating conditions of train air conditioning units not only directly affect the passenger experience, but are also closely related to the safety of train operation. The cooling power of passenger trains is equivalent to about forty household air conditioners, whether it is caused by short circuit or line aging. Fire or electric leakage will cause incalculable consequences. The maintenance personnel of Kuzhban always treat air-conditioning failures with great spirit. After tightening the last screw of the stainless steel cover of the train air conditioner, Luo Chunliang's safety rope was soaked with sweat after the malfunction was solved. He slowly took a rest, then stood up slowly. "Working at high temperature and high altitude consumes much energy and energy. It is best not to stand up immediately after a long squat to prevent fainting due to insufficient blood supply." Liu Puning said, "This is the precious experience handed down from generations of Kuriban predecessors. Safety details that everyone in the vehicle will pay attention to."
Under the dazzling sunlight, one after another, like Li Yubin, Liu Wenjie and Luo Chunliang, is sweating but meticulously completing their vehicle inspection operations. Perhaps people who have lived in Lingnan for a long time can always get used to the weather of more than 30 degrees Celsius. However, the railway car operators use 50℃, 60℃, and 70℃ to ensure the safety of the train and bring passengers a comfortable experience of 26℃. (Finish)
