In a feat of engineering, organisation and sheer hard work, Chinese labourers managed to lay part of a new railway line in just eight-and-a-half hours.
Footage shows 1,500 workers setting to work in China’s south-eastern province of Fujian.
They removed old tracks, installed new ones and added points at Longyan as part of a project to link the city with Nanping.
Workers began on January 19 at 18.30 local time, finishing the following day at 3am.
It was part of a task to upgrade a train station and connect a newly-built railway line with three existing ones.
The 246-kilometre Nanping-Longyan railway link will begin operation at the end of this year and the high-speed line will cut travel time between the two cities from seven hours to just 90 minutes.
