The Rapid Growth of China's Rapid Transit

"With its high-speed rail network, now the longest in the world, the Chinese are providing efficient intercity links into downtowns.

But it's in urban rail networks that the country has made the biggest strides towards increasing mobility within cities. Shanghai's huge Metro, the longest on earth, is just one among eleven currently operating in China. Dozens of other cities have rapid transit systems either under construction or in planning."

The central government has reportedly pledged up to $1 trillion in funding for additional rapid transit projects.
