The Qinghai–Tibet railway or Qingzang railway (Standard Tibetan: མཚོ་བོད་ལྕགས་ལམ།, mtsho bod lcags lam; simplified Chinese: 青藏铁路; traditional Chinese: 青藏鐵路; pinyin: Qīngzàng Tiělù), is a high-elevation railway line in China between Xining, Qinghai Province, and Lhasa, Tibet. With over 960 km (600 mi) of track being more than 4,000 m (13,123 ft) above sea level, it is the highest railway line in the world.

Construction began on the 815 km (506 mi) section between Xining and Golmud in 1958 and was completed in 1984; the remaining 1,142 km (710 mi) from Golmud to Lhasa started construction in 2001 and opened in 2006, making it the first railway line in Tibet. Passenger trains run from Beijing, Chengdu, Chongqing, Guangzhou, Shanghai, Xining, and Lanzhou, and can carry between 800 and 1,000 passengers during peak season.

In addition to it being the world's highest railway, the line is also the holder of numerous other records; the line includes the Tanggula Pass, the highest point on a railway in the world at 5,072 m (16,640 ft) above sea level, and Tanggula railway station at 5,068 m (16,627 ft) is the world's highest railway station. The 1,338 m (4,390 ft) long Fenghuoshan tunnel is the highest rail tunnel in the world at 4,905 m (16,093 ft) above sea level.

In 2022, the Chinese government announced plans for the line to be electrified. Construction started in June 2022 and is expected to take three years, at a total cost of 14.84 billion yuan.

Construction

The capital of the Qinghai Province, Xining, became connected with the rest of the country by rail in 1959, when the Lanqing Railway from Lanzhou was completed.

The 815 km (506 mi) section of the future Qingzang Railway from Xining to Golmud, Qinghai opened to traffic in 1984. But the remaining 1,142 km (710 mi) section from Golmud to Lhasa could not be constructed until technical difficulties of building railroad tracks on permafrost were solved. This section was formally started on 29 June 2001, finished on 12 October 2005, and signaling work and track testing took another eight months. It was completed in five years at a cost of $3.68 billion.

Track-laying in Tibet was launched from both directions, towards Tanggula Mountain and Lhasa, from Amdo railway station on 22 June 2004. On 24 August 2005, track was laid at the railway's highest point, the Tanggula Pass, 5,072 m (16,640 feet) above sea level.

There are 44 stations, among them Tanggula Mountain railway station, at 5,068 m (16,627 ft) the world's highest. Peru's Ticlio railway station at 4,829 m (15,843 ft) is the highest in the Americas (Cóndor station; at 4,786 m or 15,702 ft, on the Rio Mulatos-Potosí line, Bolivia, and La Galera station at 4,777 m or 15,673 ft, in Peru, being the next highest). The Qingzang Railway project involved more than 20,000 workers and over 6,000 pieces of industrial equipment, and is one of China's major accomplishments of the 21st century.

Bombardier Transportation built 361 high-altitude passenger carriages with special enriched-oxygen and UV-protection systems, delivered between December 2005 and May 2006. Fifty-three are luxury sleeper carriages for tourist services.

The construction of the railway was part of the China Western Development strategy, an attempt to develop the western provinces of China, which are much less developed than eastern China. The railway will be extended to Zhangmu via Shigatse (日喀则) to the west, and Dali via Nyingchi (林芝) to the east. A further extension is planned to link Shigatse with Yadong near the China-India border (Map). The railway is considered one of the greatest feats in modern Chinese history by the government, and as a result, is often mentioned on regular TV programs. Chinese-Tibetan folk singer Han Hong has a song called Tianlu (Road to Heaven; 天路) praising the Qingzang Railway.

Completed extensions

On 17 August 2008, a railway spokesman confirmed plans to add six more rail lines connecting to the Qinghai–Tibet railway, including from Lhasa to Nyingchi and from Lhasa to Shigatse, both in the Tibet Autonomous Region. Three lines will originate from Golmud in Qinghai province and run to Chengdu in Sichuan province, Dunhuang in Gansu province, and Korla of the Xinjiang Uygur Autonomous Region. The sixth will link Xining, the capital of Qinghai, with Zhangye in Gansu. The six lines are expected to be in operation before 2020. Construction work of the Lhasa–Shigatse extension began on 26 September 2010; it was opened in August 2014.

The construction of Dunhuang–Golmud railway began in December 2012 and finished on 18 December 2019. This new railway extends the existed Yinmaxia station on the Qinghai–Tibet Railway 506 km (314 mi) to Dunhuang, Gansu, establishing a direct connection between Xinjiang and Tibet.

Addition of capacity and electrification

Given that the Sichuan-Tibet railway is expected to be completed relatively later with less capacity, the Qinghai–Tibet railway is expected to add cargo capacity to fulfill the demand of material transportation. 13 stations along the Qinghai–Tibet railway have received extensions of sidings or passing loops, or these were built from scratch. This will allow the daily train received from Lhasa Railway station to expand from 6 to 12–14. An electrification feasibility study is also in progress.

Connection to Nepal

In a meeting between Chinese and Nepalese officials on 25 April 2008, the Chinese delegation announced the intention to extend the Qingzang railway originally to Zhangmu (Nepali: Khasa) on the Nepalese border. Nepal had requested that the railway be extended to enable trade and tourism between the two nations. The section Lhasa-Shigatse opened in August 2014. In June 2018, China and Nepal signed a series of agreements including the construction of Shigatse-Kathmandu railway during Nepali prime minister Oli's visit to China.

China plans to extend this railway up to Lake Paiku/Gyirong, which is around 60 km from the Rasuwa border crossing. Construction of the railway from Shigatse to Gyirong is expected to start in 2025. The final part of the whole infrastructure will be the Gyirong-Katmandu railway.

Route

This section needs expansion. You can help by adding to it. (March 2024)

Within the Golmud to Lhasa section of the line there are 45 stations, 38 of which are unstaffed and monitored by the control center in Xining. Thirteen more stations are planned.

The 4,010 m (13,160 ft) New Guanjiao Tunnel is the longest tunnel between Xining and Golmud, and the 3,345 m (10,974 ft) Yangbajing tunnel is the longest tunnel between Golmud and Lhasa. More than 960 km (600 mi), over 80% of the Golmud–Lhasa section, is at an elevation of more than 4,000 m (13,123 ft). There are 675 bridges, totalling 160 km (99 mi); about 550 km (340 mi) of track is laid on permafrost.

Existing stations

At 5,068 metres (16,627 ft) above sea level Tanggula railway station is the highest railway station in the world as of October 2024. The second through fifth and tenth highest stations (Tanggula North, Tangguala South, Tuoju, Zhajiazangbu and Jiangkedong respectively) are also on this line.

Trains and tickets

The trains are specially built for high-elevation environments. The diesel locomotives for cargo were built by CSR Qishuyan (DF8B-9000 Series) and by CNR Erqi Locomotive (DF7G-8000 Series), and the locomotives for passenger transportation were built by GE in Pennsylvania (NJ2), and the passenger carriages are Chinese-made 25T carriages: on train Z21/Z22, between Beijing West and Lhasa, Bombardier Sifang Transportation (BSP) made carriages on the Golmud-Lhasa section in deep green/yellow or deep red/yellow. Signs in the carriages are in Tibetan, Chinese, and English. The operational speed is 120 km/h (75 mph) and 100 km/h (62 mph) over sections laid on permafrost.

The railway from Golmud to Lhasa was completed on 12 October 2005, and it opened to regular trial service on 1 July 2006.

The locomotives are turbocharged to combat the power-reducing effect of having to run on about half an atmosphere of air due to extreme altitude.

At the beginning, only three trains ran: Beijing–Lhasa (every day), Chengdu/Chongqing–Lhasa (every other day), and Lanzhou/Xining–Lhasa. Shanghai/Guangzhou–Lhasa services were added in October 2006. In July 2010, the Shanghai–Lhasa service became daily, and a daily service between Xining and Lhasa was added, but the service was then suspended for the winter season.

Since October 2006, five pairs of passenger trains run between Golmud and Lhasa, and one more pair between Xining and Golmud. The line has a capacity of eight pairs of passenger trains.

Oxygen supply and medical issues

The passenger carriages used on Lhasa trains are specially built and have an oxygen supply for each passenger. Every passenger train has a doctor.

A Passenger Health Registration Card is required to take the train between Golmud and Lhasa. The card can be obtained when purchasing the ticket. Passengers must read the health notice for high-elevation travel and sign the agreement on the card to take the train. On 28 August 2006, a 75-year-old Hong Kong man was reported to be the first passenger to die on the train, after he had suffered heart problems in Lhasa but insisted on travelling to Xining.

Engineering challenges

There are many technical difficulties for such a railway. About half of the second section was built on barely permanent permafrost. In the summer, the uppermost layer thaws, and the ground becomes muddy. The heat from the trains passing above is able to melt the permafrost even with a small change in temperature. The main engineering challenge, aside from oxygen shortages, is the weakness of the permafrost. For areas of permafrost that are not very fragile, an embankment of large rocks is sufficient. Meanwhile, in the most fragile areas, the rail bed must be elevated like a bridge. The engineers dealt with this problem in the areas of weakest permafrost by building elevated tracks with pile-driven foundations sunk deep into the ground. Similar to the Trans-Alaska Pipeline System, portions of the track are also passively cooled with ammonia-based heat exchangers.

Due to climate change, temperatures in the Tibetan Plateau may be considered to increase by an estimated two to three degrees Celsius. This change is sufficient to melt the permafrost and thereby affect the integrity of the entire system. The effects of climate change on the railway have yet to be seen.

The air in Tibet is much thinner, with oxygen partial pressure being 35% to 40% below that at sea level. Special passenger carriages are used, and several oxygen factories were built along the railway. Each seat in the train is equipped with an oxygen supply outlet for any possible emergency. The Chinese government claimed that no construction workers died during the construction due to altitude sickness related diseases. The railway passes the Kunlun Mountains, an earthquake zone. The 7.8 M_w Kunlun earthquake struck in 2001 (but caused no fatalities). Dozens of earthquake monitors have been installed along the railway.

Economic

With limited industrial capacity in Tibet, the Tibetan economy heavily relies on industrial products from more developed parts of China. Transport of goods in and out of Tibet was mostly through the Qingzang Highway connecting Tibet to the adjacent Qinghai province, which was built in the early 1950s. The length and terrain have limited the capacity of the highway, with less than 1 million tons of goods transported each year. With the construction of the Qingzang railway, the cost of transportation of both passengers and goods should be greatly reduced, allowing for an increase in volume—the cost per tonne-kilometer will be reduced from 0.38 RMB to 0.12 RMB. It is projected that by 2010, 2.8 million tons will be carried to and from Tibet, with over 75% carried by the railway. Before the railway, the purchasing power of 100 RMB in Lhasa was only commensurate with 54 RMB in coastal regions of China, mainly due to high transport costs. The railway could elevate living standards along the route.

Social

Environmentalists and Tibetan independence activists protested against the construction of the railway. The Tibetan government-in-exile believes that the line and the further expansion of the rail network will contribute to further influx of Chinese people, the de-nationalization of Tibetans and the depletion of the region's natural resources.

According to Chinese state news agency Xinhua News, the Qingzang railway has promoted the inheritance of Tibetan culture and religion, as the opening of the railway has increased the number of worshippers from all over the country coming to Lhasa. It also advantages Tibetans with accessibility to the rest part of China for tertiary education, employment, and market for local industries. Qiangba Puncog, former Chairman of the Tibet Autonomous Region People's Government, has appreciated the railway for introducing more tourism industries to the region with jobs for the local people.

Environmental

The environmental impact of the new railway is an ongoing concern. The increase in passenger traffic will result in greater tourism and economic activity on the Tibetan Plateau, and the construction of the railway may also negatively impact the local environment. For example, interference on earth, vegetation, and surface water heat exchange, which may cause freeze-thaw erosion and melting of ice if not handled properly. To reduce the interference, trash and excrement on the trains are collected into two sealed containers in each car, instead of disposing them on the tracks, and are taken out at large stations. There are also concerns from the China Meteorological Administration that melting, due to global warming, of the permafrost in Tibet on which part of the railway is placed may threaten the railway within the 21st century.

The effects of this railway on wild animals such as Tibetan antelope and plants are currently unknown. 33 wildlife crossing railway bridges were constructed specifically to allow continued animal migration.

Military

Commentators have noted the potential military impact of this railway as permitting the People's Liberation Army more rapid troop mobilization to certain border areas in dispute with India.
