The Changping Line of the Beijing Subway is a rapid transit subway line in northern Beijing. The line opened on December 30, 2010 and currently runs north from the Xi'erqi station on Line 13 to Nanshao. It is 21.24 km in length with 7 stations.

After a second phase of construction, the Changping Line will be extended further north to the Thirteen Tombs Scenic Area, and will connect central Changping District with the Beijing subway network.

History

The planned route of the Changping Line was chosen from three alternatives. The other original options placed the southern terminus of the line at the Beijing North Railway Station near Line 2 at Xizhimen and at Huoying, with transfers not only to Line 8 but to Line 13 as well. One original alternative plan set Phase II at 16.7 km with one extra station beyond the Ming Tombs.

On January 5, 2009, the Changping District government signed land clearing contracts with townships along the route, with Huilongguan, Shahe and Nanshao, marking the official beginning of Phase I construction. Phase I was set to be completed by the end of 2010, and Phase II is scheduled for completion by 2012.

On September 19, 2010, the line commenced trial running with empty cars.

On December 30, 2010, Phase I of the line entered into operation.
