[Railway escorts in the mountains: go to the cold to guard the railway traffic line in the primitive forest area] "This cooling has led to different degrees of frost damage on the railway in the Yanshan section of the Yalin Line, today we must pay close attention to maintenance, rectify the frost damage, everyone should work safely, pay attention to keep warm, and set off!" ”

Just after the new year, the cold wave struck again, and the railway frost damage of the Yanshan section of the Yalin Line was once again urgent. Early in the morning, more than a dozen railway workers from the Urqi Khan line workshop of the Hailar Engineering Section gathered under the leadership of foreman Hawking Chi and rushed to the forest for maintenance.

The Yalin Line is the only railway traffic line leading to the northern forest area of Daxinganling in Inner Mongolia, which is located in an alpine area, and crosses the mountains and mountains, with frequent frost damage, and is one of the most serious railway frost damage areas in the country.

The railway workers here have to brave the cold of minus 30 to 40 degrees Celsius every day to ensure the safety and smoothness of the railway. Even as the Spring Festival approaches, they escort the railway lines in the primeval forest area in the bitter cold.

The road and railroad leading to Iwayama Station are often side by side, sitting on bumpy cars, and it is obvious that the road is uneven, and the impact of frost damage on traffic in the north can be seen everywhere.

Driver Yu Chengjun told reporters that it is about 25 kilometers to Yanshan, although the distance is not long, but the road is more uphill and slippery, and it takes about half an hour to walk.

Half an hour later, the railroad workers arrived at the frost damage job site, and the workers carried heavy tools and waded through the snow to the roadbed of the Yalin Line.

Liu Yuanlong, deputy director of the Urqi Khan line workshop of the Hailar Engineering Section, said: "The temperature is minus thirty or forty degrees, the toughness of the rail is poor, the frost is brittle, this period belongs to the period of frequent failures, and the rails are easy to break when they are serious." ”

Yanshan Station is located at 91 kilometers of Yalin Railway, affected by the comprehensive factors of geography and hydrology, every year in winter, yanshan station railway will appear "two packs and one pit" frost damage, pothole line depression maximum value of about 90 mm, is a rare national railway frost damage section.

"This location is the center mileage of the biggest frost damage at Iwayama Station, and now there is an 80 mm pit in this position, and when we renovated, this pit pad was 40 mm, and the two ends were withdrawn 40 mm, and we flattened this line." Liu Yuanlong explained to reporters while overhauling.

Line workers are heavy physical labor, working along the line, often need to change the work site. Two hours later, the railroad workers once again picked up their tools and began to march to the next frozen site in the snow below their knees.

The more the weather freezes, the faster the damage changes. Liu Yuanlong said: "This summer we learned the Qinghai-Tibet railway technology, the introduction of special frost damage sleepers and accessories, the renovation effect is quite good, the safety factor has been greatly improved." ”

Hawking Pool, 55, who is retiring this year, has worked on the Yalin Line for 36 years, witnessing the historical transformation of the Yalin Line railway from wooden to concrete pillows, from ordinary steel rails to seamless lines.

"This is the connection of two rails, resulting in rail cracks, the car once it produces vibrations, the steel rails that used to be 25 meters have now been replaced by seamless, 500 meters to 2 kilometers a rail gap, so that there is no vibration when passing through the train, and passengers are comfortable sitting." Hawking Pool pointed to a section of steel rail and told reporters.

The Yalin Line Railway starts from Hulunbuir Yakeshi City in the south to Mangui Town in Genhe City in the north, with a total distance of 441 kilometers, passing through 18 stations and 8 landing points, because there is only one train entering the forest area, even if there is no station, but as long as there is a place where there is a family, it will stop for 1 minute, so it is called "public welfare slow train".

Ding Hui, a retired employee of Yulin Forestry Farm, also called this train a "life-saving car", "This train is very important to us, sometimes going to the city to buy medicine, the elderly to see a doctor, it is very convenient." ”

"We work hard, but we're proud to think that people in the forest area can travel safely and that they're comfortable in their cars." Liu Yuanlong's frozen red face showed a smile.
