China has completed Asia’s longest 16-km single tunnel with double tracks for high-speed trains in the country’s northwest Shaanxi province, state media reported on Saturday.
The tunnel, the longest of its kind in Asia, cuts through the Qinling Mountains, according to its builders.
It is part of a high-speed rail line that links Xi’an, the provincial capital and Chengdu in China’s southwest Sichuan province.
643-km line, speed 250 kmph
The 643-km line, with a designed speed of 250 km per hour, will slash the travel time between the two cities from 16 hours to just three hours, state-run Xinhua news agency reported.
