History

During planning of Line 15, the eastern terminus was moved from Fuqian Jie^[10]^[11] to the east bank of the Chaobai River.^[2] Construction began on Phase I of Line 15 in Shunyi District on April 11, 2009.^[2]^[12] At that time, Phase I of Line 15 was only 31.15 km (19.36 mi) long with 12 stations.^[2] According to the construction schedule in 2009, the easternmost Shunyi section of Phase I (18.5 km or 11.5 mi in length with seven stations) would be opened first on December 30, 2011.^[13]^[14] The remainder of Phase I would follow in May 2013.^[2]

The route of Line 15's Phase II has been revised several times over the years. In April 2009, Phase II plans showed the western half of Line 15 running from Xiyuan Station in Haidian District, through the campus of Tsinghua University, Zhongguancun, and the Olympic Green, and joining Phase I at Wangjing West.^[2]^[10] When track-laying began in Phase I on October 28, 2009, the schedule and alignment of Phase II underwent a major revision, with one proposal extending Line 15 westward as originally planned with additional stations^[15] and another proposal sending Line 15 southward and parallel to Line 8 to provide relief for congested Line 4 and 5.^[16]^[17] Ultimately the route west to Qinghuadongluxikou was selected and the design of Xiyuan station leaves enough space to build another platform in between Line 4 and Line 16 platform for potential Line 15 extension westward beyond Qinghuadongluxikou.^[18] Additionally the construction schedule was revised with Phase I expanded from 31 km (19 mi) and 12 stations to 38 km (24 mi) and 18 stations. Phase II plans also underwent a revision; instead of two sections, Phase II would be built and opened in three sections.

The first section of Phase I, from Wangjing West to Houshayu, opened on December 30, 2010. The second, from Houshayu to Fengbo, followed at the end of 2011. The third section, from Qinghuadongluxikou to Wangjing West, opened on December 28, 2014.^[6]

On 8 July 2022, an EIA document regarding Phase III construction of Beijing rail transport system (2022–2027) announced the phase 2 of line 15, with 3.5 km long extension from Fengbo to Nancai.^[19]

* Wangjing East station did not open in 2010 due to lack of connections with the surrounding road system. It was opened on 31 December 2016.

** Datunlu East station did not open in 2014 because the transfer corridors to Line 5 were still under construction. It was opened on 26 December 2015.
