CCTV News: Yongbei Railway is the main passenger transport channel in the Beibu Gulf region of Guangxi. During the Spring Festival travel rush, the density of trains increased significantly. To ensure the safety of passengers' travel, the "railroad flaw detector" needs to regularly push the "flaw detector" and carefully check every inch of the line to see how they work.


At 1:20 a.m., the line was biting cold. Tang Ziqi, a high-speed rail flaw detector from the Qinzhou Industrial Zone, and his colleagues carried the rail flaw detector to Beihai Station of Yongbei Railway. They were going to "discover" 11 switches within 240 minutes.
Tang Ziqi, a flaw detector from the Qinzhou Working Section of the Nanning Bureau of the National Railway, introduced that the position and size of the injury are judged through the waveform diagram on the screen, and a "diagnosis certificate" is given to the injury. Then the line maintenance personnel will inspect the injury.

The cold winter is the season when rails are most prone to problems. In addition, the density of trains has increased significantly during the Spring Festival travel rush. If the "lesions" cannot be discovered in time, it will affect the safety of the EMU. When he walked to the vicinity of turnout No. 38, Tang Ziqi found that the instrument showed abnormality and finally confirmed that this was a fish bruise near the surface of the rail. The depth of the injury was 5 mm, which reached the standard of minor injuries. Immediately, the flaw detectors urgently reported and repaired.

Tang Ziqi said that this rail flaw detector weighs more than 80 kilograms of water. He lifts it up and down on the line every day. His hands are often blisters and his legs are bruised many times. I push the instruments online every day, and in one month, the total amount is more than 80 kilometers.

At 4:30 in the morning, they completed the flaw detection work of the last set of switches, packed up various tools and carried the flaw detection cart. In this quiet early morning, their figures silently protected the safety of the Spring Festival travel rush.
