History During planning of Line 15, the eastern terminus was moved from Fuqian Jie to the east bank of the Chaobai River. Construction began on Phase I of Line 15 in Shunyi District on April 11, 2009. At that time, Phase I of Line 15 was only long with 12 stations. According to the construction schedule in 2009, the easternmost Shunyi section of Phase I ( in length with seven stations) would be opened first on December 30, 2011. The remainder of Phase I would follow in May 2013.
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 at Wangjingxi. When track-laying began in Phase I on October 28, 2009, the schedule and alignment of underwent a major revision, with one proposal extending Line 15 westward as originally planned with additional stations and another proposal sending Line 15 southward and parallel to Line 8 to provide relief for congested Line 4 and 5. Ultimately the route west to Qinghua Donglu Xikou 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 Qinghua Donglu Xikou. Additionally the construction schedule was revised with Phase I expanded from and 12 stations to and 18 stations. plans also underwent a revision; instead of two sections, Phase II would be built and opened in three sections.
The first section of , from Wangjingxi to Houshayu, opened on December 30, 2010. The second, from Houshayu to Fengbo, followed at the end of 2011. The third section, from Qinghua Donglu Xikou to Wangjingxi, opened on December 28, 2014.
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.
