China to build world's most challenging railway
The Sichuan-Tibet Railway will be the second railway into southwest China's Tibet Autonomous Region after the Qinghai-Tibet Railway.
The line will go through the southeast of the Qinghai-Tibet Plateau, one of the world's most geologically active areas.
"The construction and operation of the Sichuan-Tibet Railway must overcome the biggest risks in the world," said You Yong, chief engineer of the Institute of Mountain Hazards and Environment of the Chinese Academy of Sciences (CAS), who is leading a scientific and technological support team to avoid disasters in the mountains.
China Railway Eryuan Engineering Group Co. Ltd., which is designing the line, said it will run from Chengdu, capital of southwest China's Sichuan Province, through Ya'an and Kangding, and enter Tibet via Qamdo.
It will then go through Nyingchi and Shannan prefectures before arriving at Lhasa, capital of Tibet.
The total construction length will be about 1,700 kilometers and it will cost 250 billion yuan (about 36.88 billion U.S. dollars). ■
