Construction
Located in a valley between Gangdis and Himalayas in southeast Tibet, over 90% of the tracks are at an elevation of more than 3,000-metre (9,800 ft) above sea level.[6] The railway crosses the Yarlung Tsangpo River 16 times and has 47 tunnels and 121 bridges.[7] It is part of the under-construction Sichuan–Tibet railway that will connect Lhasa and Chengdu, capital of the neighboring Sichuan province.[8] Lhasa-Nyingchi railway is the first fully-electrified railway in Tibet region.[9][10] The rolling stock is the China Railway CR200J Fuxing series powered by both electronic motors and internal combustion engines, marking the complete coverage of Fuxing series to all provincial-level regions in China.[11] The newly opened train route provides Nyingchi with access to railway services for the first time in history.[12]
History
On 4 November 2014, the National Development and Reform Commission approved the construction of Lhasa–Nyingchi railway.[13] The Sangzhuling Tunnel (桑珠岭隧道) started engineering works on 19 December 2014.[14] Construction began on 28 June 2015, and the track-laying work was completed by the end of 2020.[8]
On 25 June 2021, the railway began operation, with the first train leaving Lhasa for Nyingchi at 10.30 am. Compared with roads, the railway reduces the travel time from Lhasa to Nyingchi from 5 hours to 3.5 hours, and cuts the travel time from Shannan to Nyingchi from 6 hours to more than 2 hours.[2]
Rolling stock
160 km/h services use the China Railway CR200J trainsets.[15] CR200J Plateau variant will serve the railway, and it's a type of bi-mode locomotive specifically designed for plateau operations.[16] 31 sets of train in 12 car configuration is in service. A combination of diffusion and distributed oxygen systems are installed to help alleviate altitude sickness for passengers on the trip.[10]
