China opens the world’s highest rail tunnel

Construction work on the world’s highest rail tunnel has been completed in China and is expected to be used by rail services by the end of the year.

The 16.3km long tunnel is located at an altitude of 3,607m and takes a rail line from the autonomous region of Xinjiang Uygur and the Gansu province through the Qilian Mountains.

Completion of work on the tunnel by China Railway 20th Group Co, which started in 2009, will cut the journey time between the two regions from 20 hours to eight.
