Beijing plans to build a second subway loop line, in a bid to improve the city's metro network, China Radio International reported on Monday.

Currently there's only one loop line in the center of the city. The second line is expected to pass through the Zhongguancun high-tech zone, the central business district (CBD) in the east, and the Olympic park in the north of the city.

More subways and light rail lines will also be built to serve the outskirts of Beijing.

And by 2020, if all goes to plan, Beijing will have 16 subway lines, 6 light rails, and 6 railways.
