            At Yueshan Station under the management of China Railway Zhengzhou Group Co., Ltd., there are dozens of tracks and more than 20000 train carriages are handled every day. Trains loaded with coal and other materials come and go here every day, and then go to different destinations.

            In such a "vital station", a group of doctors specialized in conducting "medical examinations" for the steel rails are regularly welcomed. These doctors are 8 inspectors from the rail inspection team of the Yueshan Engineering Section of Zhengzhou Bureau Group Company.

            It is understood that these flaw detection workers are best at "doing B-ultrasound". When operating the rail flaw detector, they first apply special detection liquid to the rail, and then use the principle of sound wave reflection to detect the internal situation of the rail, in order to accurately diagnose the "condition" of the rail and ensure the safety of railway operation.

            B-ultrasound doctors are conducting tests on the railway tracks.


            It is now early summer, with a warmer climate and a large temperature difference between day and night, which is a critical time for rail problems and one of the busiest times of the year for rail doctors.

            Facing the scorching sun, they had to push the steel rail flaw detector forward at a speed of no more than 2 kilometers per hour on the railway track every day, observing the waveform on the display screen with their eyes and listening to the alarm sound emitted by the instrument with their ears, without any hesitation. Once there is an abnormality, they stop and double check, fearing that "misdiagnosis" or "missed diagnosis" may affect the safety of train operation. And this journey takes seven or eight kilometers, four or five hours.

            Li Jinlin, the leader of the inspection team responsible for leading the work, told China News Network that there should be no simplification or laziness in the entire inspection process, as it will affect the inspection results. Squatting on the sleeper will numb your legs in a moment, and if you stand up too fast, you will feel a dizzy sensation.

            I have been in this industry for so many years, but the more I work, the more timid I become. The more I work, the more scared I become. I am most afraid of my phone ringing in the middle of the night Li Jinlin told reporters on China News Network that every phone call means there is a problem with the steel rail.

            Every day, there are 5000 tons of heavy-duty trucks and thousands of passenger cars running on the rails. If there is a problem with the rails, I can't even imagine the consequences, "said Li Jinlin.

            The best way to make oneself not afraid is to improve the team's technical level and sense of responsibility, "said Li Jinlin. In the past five years, their team's" B-ultrasound doctors "have relied on their superb medical skills and sense of responsibility, and have not missed a single responsibility test. (End)
