It used to take the best part of 24 hours to travel by train from Beijing to the southern boomtown of Guangzhou. But as of Wednesday, when the world's longest high-speed rail line opened for business, the 1,428-mile journey has been cut to a mere eight hours.

The trains travel at an average speed of 186mph, passing through five provinces as they tear through the countryside.
