CHINA: Construction work on the Chengdu - Lanzhou railway officially began on February 21 and is expected to last for six years.

As the route runs through the country’s protected corridor for giant pandas, parts of the line will be built in tunnel, and extra bridges will be provided to minimise the impact on the animals’ lifestyle.

Chinese Railways has also suggested that it will aim to timetable trains through the so-called ‘core area’ in the evenings as far as possible.
