China's superlative rail network

China leads the way in the longest, largest and fastest transportation systems.

EVERYONE knows about the Great Wall of China, widely considered one of the Seven Wonders of the Ancient Age. Snaking for several thousands of kilometres when it was finally joined together over hundreds of years, the wall came to symbolise a united China, especially during the reign of Qin Shihuang (260BCE–210BCE), the first emperor, and onwards.
