Beijing plans to extend its subway to 200 kilometers of track by 2008, aiming to ease its traffic pressure, said an official of the Beijing Municipal Committee of Communication (BMCC).

With a goal of the Summer Olympic Games in 2008, Beijing has accelerated its improvement of the transportation system, said Liu Xiaoming, deputy director of BMCC Tuesday.

With a total length of 86 kilometers, No. 4, No. 5, No. 10 subways and the branch line for the Olympic Games are now under construction or in the planning stages. All are expected to be in operation by 2008, said Liu.
