Beijing's subway is going full bore

Two more new lines will connect with the massive matrix of Beijing subway construction projects in 2017, adding to the 20 projects already in progress, officials announced on Wednesday.

The two lines - Line 28 and the Yanfang Branch Line - will mark the start of construction of all the lines that have been approved in the current master plan, said Yang Guangwu, chief engineer of Beijing Major Projects Construction Headquarters Office, coordinator of Beijing's subway construction.

Line 28, also known as the CBD Line, will run through eight stations under Beijing's central business district as well as the Beijing East Railway Station in Chaoyang district. Planners expect the line to relieve congestion in the area.
