[Escort Spring Festival travel rush] Working at MINUS 20 degrees Celsius Luliangshan "Tunnel Iceman": It is only for the safe passage of trains day and night.

  Cctv news(Reporter Cui Mingming, reporter from Liu Chang, wanglili, Zhao Zhechang): There are such a special group of people on duty along the railway in Shanxi mountainous areas. Every winter, they will go into the dark tunnel to remove icicles formed by water seepage, so as to ensure that the Taiyin Bank Railway, which runs through the railway artery in the central and western regions of China, will complete the heavy responsibility of transporting 60 million tons of western energy to the east every year and safely pass 68 trains. This group of people is called "tunnel icebreakers".

  As the third longest tunnel in Asia, the Luliangshan Tunnel, with a total length of 20.7 kilometers, is the main traffic route for Lvliang to the outside world. The tunnel is located in the mountainous area, and mountain spring water flows into the tunnel all the year round. With the sudden drop of temperature, hundreds of "ice runners" will form in the tunnel in one night. If it is not cleaned in time, it will damage the structural surface of the tunnel side wall, ballast bed and ditch cover plate, which will cause great safety hazards to the operation of passenger cars.

  At this time, the workers of taiyuan railway administration Taiyuan South Works Section wearing lighting lamps and holding special pickaxes and steel bars will appear here. They will stand on the ladder, tie safety ropes, and pay attention not to hurt the cables while picking axes and smashing ice. In this way, the ice is constantly knocked and the salt is sprinkled, just to ensure that the train with a speed of 160 kilometers per hour can pass safely.

  Similarly, the 434-kilometer Taijiao Railway is an important channel for the transportation of Shanxi coal. Every four hours, the staff of Yushe Bridge and Tunnel Workshop of Taiyuan Works Section of Taiyuan Bureau will clear 42 hidden ice spots of six tunnels along the route.

  Cheng Xuliang, the foreman, said that the popsicle they used was 6 meters long and consisted of three irons, each weighing 40 kilograms. If they didn’t master it well, sharp ice slag and ice cubes would fall with the popsicle, and they were often injured by the falling ice cubes.

  In the working environment of MINUS 20 degrees Celsius, these ice skaters are steaming on their heads. Although they are called "ice skaters", in fact, ice skating is only part of their work, and they have to check the facilities, equipment and lines. Every year in Spring Festival travel rush, they stick to their posts, and use the achievements of more than 5,000 cubic meters of ice to get the trains running smoothly.
