Unprecedented construction of Beijing's gigantic underground transit network is expected to alleviate traffic problems that have been haunting the metropolis for decades, reports Zheng Xin.
The Beijing Subway has seen unprecedented construction in recent years, greatly easing traffic congestion in the Chinese capital.
Including a new line and extensions to lines, the city boasts a network of 15 lines, covering 11 districts, with 221 stations and 442 km of track.
Wang Renqiang, a leading project official of the subway's Line 6 project department of the China Railway Tunnel Group, said once everything is operational, the updated network will make it easier for people to get around and provide relief to transport services on the ground.
