History

The stretch of Changping line, south of Gonghuacheng station.

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, or at Huoying, with transfers to Line 8 and Line 13. One original alternative plan set Phase II at 16.7 km (10.4 mi), with one extra station beyond the Ming Tombs.[23]

On January 5, 2009, the Changping District government signed land clearing contracts with townships along routes through Huilongguan, Shahe, and Nanshao, marking the official beginning of Phase I construction.[12] Phase I was set to be completed by the end of 2010, and Phase II was scheduled for completion by 2012.[12]

On September 19, 2010, the line commenced trial running with empty cars.[24]

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

On December 26, 2015, Phase II of the line entered into operation, extending the line north underground for another 5 stations.

On December 31, 2021, a one-station extension to Qinghe railway station opened.

On February 4, 2023, the extension to Xitucheng opened.[4]

Ridership

During rush hours, in 2013, the section between Life Science Park and Xi'erqi Stations was the most congested section in the Beijing subway network, operating at 132% capacity.[25]
