CCTV News: Railway rail flaw detection workers are a special type of work in the railway transportation system. Their work is like that of doctors doing B-ultrasound in hospitals, and their "patients" are the two rails running on trains. Due to the heavy instruments operated by railway rail flaw detection workers, in the past, flaw detection workers tended to choose males. However, during this year's Spring Festival transportation, three girls from the Qingdao Works Department of Jinan Railway Bureau entered the man's sole inspection team.

Liu Yanhong, Wang Lei, and Jiang Lin, these three beautiful girls, have an average age of less than 23 years. After graduating from university, they successively entered the Qingdao Engineering Department of Jinan Railway Bureau and became inspectors.

On January 20th, during the Lunar New Year, this year was their first time investing in railway track support during the Spring Festival Festival, and they were also in the same inspection team. Their task section was the Qingdao section of the Jiaohuang Railway, which was also a key line for inspection operations during the Spring Festival Festival.

Wang Lei, a steel rail flaw detector at the Qingdao Works Section of Jinan Railway Bureau, said that the Jiaohuang Line has more damage compared to other lines. Many injuries have been found on this line before, and this time we are going to double check to ensure that passengers can safely return home during the Spring Festival transportation.

The flaw detection operation for the three kilometer Jiaohuang Railway needs to be completed within a two hour window period, otherwise it will affect the normal operation of the train and even cause accidents.

Jiang Lin, a steel rail flaw detector at the Qingdao Public Works Section of Jinan Railway Bureau, said: It is important to complete the work during the window period. If this time is needed again next time, it will not be easy to do so.

Reporter: Are you sure?

Jiang Lin, a rail flaw detector at the Qingdao Works Section of Jinan Railway Bureau: Well, I'm sure.

Before going on a daily expedition, three people must test the testing equipment to ensure that the instruments are working properly.

After the last train left their task section, the three of them and other colleagues divided into two groups to start working on the road. Jiang Lin arrived at the engineering department one year earlier than Liu Yanhong and Wang Lei, and is also considered a veteran of the Spring Festival Movement.

Women who do men's work, not to mention the pressure in their hearts, are often injured when their weak bodies push heavy machines along the tracks and road pillows.

Jiang Lin, a steel rail inspector at the Qingdao Works Section of Jinan Railway Bureau, said: 'It's just some minor injuries like knee bumps, which often hit the stone ballast.'. It's all minor injuries, and it's not a serious matter.

Every time I go home, my parents see Jiang Lin's injury and are afraid that she won't be able to persevere, so I plan to change jobs for her. Jiang Lin always refuses, feeling that men can do as much work as women.

Jiang Lin, a steel rail inspection worker at the Qingdao Public Works Section of Jinan Railway Bureau: If you don't do it, there will always be someone to do it. Our work actually has a sense of responsibility and achievement, and we can ensure the safety of passengers and trains.

Wang Lei is the youngest of the three girls in terms of age, size, and strength. When she first started working as a flaw detector a few months ago, she couldn't control the dozens of pounds of equipment at all, and being criticized by her master was a common occurrence. Especially during the Spring Festival transportation period, the train passing rate is extremely high, leaving a short window for inspection. Stability, accuracy, and speed are the most basic requirements for inspection workers. Wang Lei put in a lot of effort before the Spring Festival transportation.

Wang Lei, a steel rail inspector at the Qingdao Public Works Section of Jinan Railway Bureau, said that compared to boys, his physical strength is a bit inadequate.

For Wang Lei, who loves beauty, her initial wish when she entered the railway system was to be a dignified and beautiful railway attendant like her classmates, but she didn't even expect to become a flaw detector herself.

Liu Yanhong, the more aggressive of the three, not only had the best conversation with her male colleagues, but also learned from them how to use her hand instead of a steel ruler to measure the direction of the rail alarm.

Liu Yanhong, a steel rail flaw detector at the Qingdao Public Works Section of Jinan Railway Bureau: When I have nothing to do, I usually use that ruler to measure the length of my maximum knuckles and the centimeter of the second knuckles, so I remember.

This move was very helpful for accelerating the speed of inspection during the Spring Festival Movement period, and also became a "trump card" for the three of them to complete their tasks on time. The two hour window period was coming quickly, and they had just moved the inspection equipment out of the track when the train sped by.

Yang Xiaori, a steel rail inspector at the Qingdao Public Works Section of Jinan Railway Bureau, said: Our male comrades used to work too much and feel tired. Since seeing their spirit, they have not often mentioned how much work they have and how tired they are.

100% accuracy of "stable, accurate, and fast" flaw detection

During the Spring Festival transportation period, when more trains are added, the damage to the railway tracks caused by trains will increase. Therefore, inspection operations are also conducted day and night.

In January, the land of Qilu was cold and piercing, and thick coats couldn't block the rustling north wind, which brought greater difficulties to their work. Flaw detection operations require them to carefully distinguish the sound of the equipment and record the detection data at any time, so earbuds and gloves cannot be worn during the operation. Frostbite is the biggest threat they face.

Yang Xiaori, a steel rail inspection worker at the Qingdao Public Works Section of Jinan Railway Bureau, said: To be honest, this job is also very tiring for our male comrades. Many of the time is at night, and our schedules are not fixed, and sometimes we can't eat.

In order to ensure the safety of the Spring Festival transportation and make up for the lack of on-site inspection experience, the three girls spent almost all of their spare time training two months before the start of the Spring Festival transportation.

Jiang Lin, a steel rail flaw detector at the Qingdao Works Section of Jinan Railway Bureau, said: This steel track is basically visible to all injuries, so that when we find such injuries on site, we will have a sense of familiarity and improve our accuracy in identifying them.

From the first day of the Spring Festival transportation to the present, the inspection team composed of three girls born in the 1990s has achieved 100% accuracy in the inspection, ensuring the safety and smoothness of the journey home during the Spring Festival transportation.
