Tibet Railway
Tibet Railway
The Tibet Railway (Qinghai-Tibet Railway) is a high-altitude railway that connects Qinghai Province’s Xining to Tibet Autonomous Region’s Lhasa. As a symbolic project of China's West Development Strategy, it plays a significant role in accelerating the social and economic development of Qinghai Province and Tibet Autonomous Region.
The total length of Qingzang railway is 1,956 kilometers. The 814 kilometer-long stretch from Xining to Golmud was built in 1979 and started operation in 1984. The 1,142 kilometer stretch between Golmud and Lhasa runs south along the Qinghai-Tibet Highway and was constructed by rebuilding the original 32-kilometer-long line from Golmud to Nanshankou and laying 1,110 kilometers of new track. This railway is the first to connect the central plains of China with Tibet Autonomous Region, which due to its altitude and terrain is the last province-level entity in mainland China to have a conventional railway. Testing of the line and equipment started on 1 May 2006.
The work started on June 29, 2001. Up to March 25, 2006 investment in the project stood at 28.5 billion yuan (about US$3.6 billion) – 1.2 billion yuan (US$150 million) of which was spent on environmental protection projects. Trial operations will begin on July 1, 2006 with a total investment of 6.5 billion yuan (US$812 million) being made in this part of the project.
The railway construction was complex and highly demanding for those involved. They confronted a range of challenges including perennial frozen ground, severe cold, a lack of oxygen because of the altitude and care had to be taken with the fragile ecology which was all round the construction work. The railway covers 960-kilometers at an altitude of more than 4,000 meters and over 550 kilometers within the "frozen earth" area.
The line includes the Tanggula Pass, at 5,072 meters (16,640 feet) above sea level the world's highest rail track. The 1,338 m Fenghuoshan tunnel is the highest rail tunnel in the world, at 4,905 m above sea level. The 4,010-m Guanjiao tunnel is the longest tunnel from Xining to Golmod and the 3,345-m Yangbajing tunnel is the longest tunnel from Golmod to Lhasa. More than 960 km, or over 80% of the Golmud-Lhasa section, is at an altitude of more than 4,000 m. There are 675 bridges, totalling 159.88 km, and about 550 km of the railway is laid on permafrost.
Passenger trains run from Beijing, Chengdu, Chongqing, Guangzhou, Shanghai, Xining and Lanzhou. The trains are specially built for high altitude environment. The diesel locomotives used on Golmud-Lhasa section were made by GE in Pennsylvania, and the passenger carriages are Chinese-made 25T carriages: on train T27/T28, between Beijing West and Lhasa, BSP carriages are from Bombardier. Carriages used on the Golmud-Lhasa section are either deep green/yellow or deep red/yellow. Signs in the carriages are in Tibetan, Chinese and English. The operational speed is 120 km/h, 100 km/h in sections laid on permafrost.
The Qinghai-Tibet Plateau has long been described as "the Roof of the World" and the third polar region. It's the starting point of many of China's rivers. In building the Qinghai-Tibet Railway, great care has been taken to protect the unique, fragile and sensitive geographical environment of this plateau.
