History

In 2019, Liu Xuesong, representative of the Beijing Municipal People's Congress and general manager of Capital Airport Holding, suggested building the northern section of the line in advance.

On November 10, 2020, the Shunyi Branch of the Beijing Municipal Planning and Natural Resources Commission released a notice to advance the preliminary work of rail transit, including the Shunyi section of Line 20.

According to the information released on January 11, 2022, the first phase of the line is included in the "Beijing Rail Transit Phase III Construction Plan". On 8 July 2022, the EIA of Phase III Plan announced that it will be a 19 km (12 mi) line, with 4 stations from Guanzhuangluxikou in Chaoyang District to Linhe in Shunyi District.
