Qingzang railway
The Qingzang railway, Qinghai–Xizang railway, or Qinghai–Tibet railway (simplified Chinese: 青藏铁路; traditional Chinese: 青藏鐵路; pinyin: Qīngzàng Tiělù; Tibetan: mtsho bod lcags lam མཚོ་བོད་ལྕགས་ལམ།), is a high-altitude railway that connects Xining, Qinghai Province, to Lhasa, Tibet Autonomous Region, in People's Republic of China.
The total length of Qingzang railway is 1956 km (1215 mi). Construction of the 815 km (506 mi) section between Xining and Golmud was completed by 1984. The 1142 km (709 mi) section between Golmud and Lhasa was inaugurated on 1 July 2006 by president Hu Jintao: the first two passenger trains were "Qing 1" (Q1) from Golmud to Lhasa, and "Zang 2" (J2) from Lhasa.[1] This railway is the first to connect the Tibet Autonomous Region to any other province, 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.[2] Passenger trains run from Beijing, Chengdu, Chongqing, Guangzhou, Shanghai, Xining and Lanzhou.[3]
The line includes the Tanggula Pass, which, at 5,072 m (16,640 feet) above sea level, is 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.
