China News Network Lanzhou, April 2 (Qiangwang Wanghui) At 18:00 on April 1, when the K1518 train passed the Changchuan to Zhujiayao section after the Baolan Railway, the train operation section was closed, and the Lanzhou Railway Bureau Lanzhou West More than 300 railway workers who had been "latent" in the "peaks and peaks" in the works section had held "guns and short cannons" in a battle situation.

The Baolan Railway is an important trunk line from North China to the Northwest. It plays an important role in accelerating the economic construction of Inner Mongolia, Ningxia, and Gansu. It runs through the Tengger Desert for more than 140 kilometers and is the first desert railway in China.

After the Baolan Railway, the line between Changchuan and Zhujiayao runs through the winding mountains of Orangutan Bay. The curve radius is small, the wind and sand along the line are large, and the design speed is low. The original type II and 69 concrete sleepers are no longer able to meet the current passenger requirements. For cargo transportation, a major "reborn" surgery is urgently needed.

The Lanzhou West Engineering Section, which undertook the construction of the Baolan Line for centralized repair, started on March 20 and used 40 days to manage three pipelines: Changchuan-Zhujiayao, Hongxiantai-Wujiayao, and Great Wall-Jingtai. 20787 type II, ШB and 69 type sleepers were replaced on the 12.47km section.

At 18:16, more than 300 railway employees, in 67 groups, carried out the sleeper replacement operation on the 400-meter line and the tamping operation of the machine.

Arrange to ensure that the track frame is stable, quality meets standards, and meets train operating conditions.

Aiming at the problem of operator and equipment material access, poor protection and communication, etc., this section conducts daily surveys of the operator ’s travel path in advance, adds guards, sets up ball control, eliminates protection failures, and ensures that the centralized construction period is completed and the quality is up to standard. .
