### South extension (section 2) to Xueyuannanlu

## 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, 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.
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. Phase I was set to be completed by the end of 2010, and Phase II was 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.
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.
On December 15, 2024, Zhufangbei and another one-station extension to Jimen Qiao opened.

## 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.

## Accident

On December 14, 2023, two Changping line trains collided between Xi'erqi station and Life Science Park station, causing one of the carriages to break apart. At least 515 people onboard were injured. The service between Xi'erqi and Zhuxinzhuang station was suspended due to the accident. On December 16, the full service on Changping line resumed.
On July 25, 2024, an out-of-service SFM93 train (set CP064) partially derailed on the siding of Qinghe railway station. Car CP0641‘s second bogie was derailed, causing service suspension between Xi'erqi station and Xuezhiyuan station section for five hours.
