[Explanation] Duma is a post-95 ground service mechanic in the EMU workshop of Shenyang Depot of China Railway Shenyang Bureau Group Co., Ltd.

During the Spring Festival, Duma has to work from evening to early morning, walking more than 20,000 steps and checking tens of thousands of parts.

　　[Explanation] In the evening, the Huanggutun Passenger Car Maintenance Depot in the EMU Workshop of Shenyang Depot was brightly lit.

The 25-year-old Duma sorted out his work clothes, put on a mask and hard hat, and started his overnight work.

For the operation of high-speed trains, safety is more important than everything else, and ground mechanics are also known as "motor train doctors".

At 21:04, the newly added D821 train stopped at Shenyang Station during the Spring Festival.

After the passengers get off the train, the train is put into the warehouse for a comprehensive "physical examination".

Duma is mainly responsible for the status inspection of the roof pantograph and on-board service facilities.

The pantograph is the power source of the motor car, and a slight error will lead to a malfunction.

Duma flashed a flashlight and cooperated with detection equipment, "look, smell, cut..." Duma did not miss every link.

From one car to another, one car is overhauled and the next car is waiting.

　　I was lazy when I was in school and liked to stay in the dorm.

Now after going to work, I basically have to walk more than 20,000 steps at night (every day), and people have become more diligent.

　　[Explanation] In Duma's pocket, he habitually put a few pieces of chewing gum, which was his "good medicine" against sleepiness at night.

At 4:30 in the morning, the D822 train left the warehouse on time, and Duma had time to eat something.

　　D822 was out of the warehouse earlier, and the time was relatively tight, and I couldn't drink a few sips of water in the middle, so I went upstairs to eat a few mouthfuls of bread, otherwise it would be easy to have low blood sugar.

　　[Explanation] At 5:52, the D822 EMU drove passengers away from Shenyang Station, and Duma and his co-workers also ended their overnight work.

During the Spring Festival travel period, the train will go online according to the full map.

Duma and his co-workers have to complete the inspection and maintenance of 18 vehicles, more than 70 items and tens of thousands of parts.

Tight time and great responsibility.

In these "motor car doctors" with sleepless night after night, the travel safety of passengers has been locked with a strong lock.
