A new railway is opening on Thursday in Northwest China's Xinjiang Uygur autonomous region, forming the world's first railway loop circling a desert, national railway operator China State Railway Group said on Wednesday.

The 825-kilometer line, linking the city of Hotan with the county of Ruoqiang in the Bayingolin Mongol autonomous prefecture, is on the southern edge of the Taklimakan Desert.

The line, with a designed speed of 120 km/h, will connect to the Korla-Kashgar, Kashgar-Hotan and Golmud-Korla railways, forming a 2,712-km-long loop line circling the Taklimakan.

The line has 22 stations, half of which provide passenger service. The journey from Hotan to Ruoqiang will take about 11-and-a-half hours.

The loop line will pass five prefecture-level regions in Xinjiang and connect to the Golmud-Korla railway, which links the city of Golmud in Qinghai province and the city of Korla in Xinjiang. This will be the third railway linking Xinjiang with other parts of China.

The line brings railway service to some new places in southern Xinjiang, boosting socioeconomic development and promoting rural vitalization in the region.

About 65 percent of the new line-534 km-is in the sand and storm zone, which made construction tremendously difficult.

Construction, which began in 2018, used a method of prefabricating 434 bridge piers and then assembling them on site.

Reducing harm

In some sections with strong wind and shifting sand dunes, designers built bridges to allow the sand and wind to pass beneath them, reducing any harm to the line.

Grass, trees and shrubbery are also planted along the rail line as a barricade against sand.

Confronted with an intricate natural environment, the company set up a management and construction team with rich experience in desert railway construction, as well as a research team, said Zhang Gang, project manager of China Railway's 14th Bureau Group.

Sand control comes before railway construction," said Wang Jinzhong, an engineer on the railway.

Workers created straw grids to cover nearly 50 square km near the railway line and planted nearly 13 million shrubs and trees, Wang said.

"Tall trees have been planted along the outer areas to reduce wind speeds, while shrubs have been planted along the inner areas of the railway to fix the sand problem," Wang said, adding that smartphones are used to control an automatic irrigation system.

Two passenger trains are scheduled each day, as well as eight freight trains that will transport cotton, walnuts, dates and other commodities to the rest of China.

Faster trains

Meanwhile, the national railway network will adopt a new train schedule starting on Monday, with changes including new lines and faster travel on existing lines, China State Railway Group said on Wednesday.

Beginning on Monday, bullet trains will be operated at the increased maximum speed of 350 km/h along the high-speed rail line linking Beijing and Wuhan, Hubei province, which is part of the line connecting Beijing and Guangzhou, Guangdong province.

That will cut the travel time between Beijing and Wuhan to 3 hours, 48 minutes-a half-hour faster than now. The Beijing-Guangzhou line is one of China's major north-south corridors for high-speed trains.

Fifty-seven trains will be operated on the faster line, reducing travel time between Beijing and many provincial capitals, including Shijiazhuang, Hebei province; Zhengzhou, Henan province; Changsha, Hunan province; Xi'an, Shaanxi province; Nanchang, Jiangxi province; Chengdu, Sichuan province; and Guiyang, Guizhou province.
