The Changping Line of the Beijing Subway (Chinese: 北京地铁昌平线; pinyin: běijīng dìtiě chāngpíng xiàn) is a rapid transit line in northern Beijing. It is 43.8 km (27.2 mi) in length with 20 stations. Changping line's color is pink.
The southern extension to Jimenqiao station is 12.6 km (7.8 mi) in length,[4] including a 0.36 km (0.22 mi) elevated section and a 12.24 km (7.61 mi) underground section.[5] The extension will add 8 underground stations to the line.[4] The one-station extension to Qinghe railway station opened on December 31, 2021, and the section between Qinghe railway station and Xitucheng opened on February 4, 2023, with 5 new stations.[6][7] The rest of south extension, include Zhufangbei and Jimenqiao stations (interchange to Line 12) will be opened on 15 December 2024.[8]
The line started construction in 2009. In September 2010, construction of Phase I was completed, and was followed by a three-month test run. Phase I of the line opened on December 30, 2010, and ran north from the Xi'erqi station on Line 13 to Nanshao station.[15] It connects the central Changping District with the Beijing subway network.[16]
A further southern extension to Xueyuannanlu is planned. It will interchange with Line 9 and Line 13A at Xueyuannanlu station (formerly known as Mingguangqiaoxi station).[22][23] This extension is still under planning and construction has not started.[24]
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.[25]
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.[16] Phase I was set to be completed by the end of 2010, and Phase II was scheduled for completion by 2012.[16]
On September 19, 2010, the line commenced trial running with empty cars.[26]
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 February 4, 2023, the extension to Xitucheng opened.[6]
On December 15, 2024, Zhufangbei and another one-station extension to Jimenqiao opened.
