China on Thursday completed the track-laying work for a railway line linking the cities of Lhasa and Nyingchi in Tibet, close to the Indian border in Arunachal Pradesh, official media here reported. The Sichuan-Tibet Railway will be the second railway into Tibet after the Qinghai-Tibet Railway. It will go through the southeast of the Qinghai-Tibet Plateau, one of the world’s most geologically active areas. The Sichuan-Tibet Railway starts from Chengdu, capital of Sichuan Province and travels through Ya’an and enters Tibet via Qamdo, shortening the journey from Chengdu to Lhasa from 48 hours to 13 hours. Linzhi, also known as Nyingchi, is located close to Arunachal Pradesh border.
