Line 7 of the Beijing Subway (Chinese: 北京地铁7号线; pinyin: běijīng dìtiě qīhàoxiàn) is a rapid transit line in Beijing. It runs parallel and to the south of Line 1 and Batong line, from the Beijing West railway station in Fengtai District to Universal Resort in Tongzhou District.

## Planning

Line 6 was originally conceived in 1973 as a "pan-handle" shaped route incorporating the central sections of today's Lines 6 and 7. In 1983 Line 6 was dissolved into two distinct lines. The section under Guang'anmen, Luomashi, Zhushikou and Guangqumen Streets and the "handle" branch to Fengtai became Line 7. The rest of the loop with a new south eastern extension to what was at the time the Beijing Jiaohuachang (Coking Plant) complex became Line 6. Line 7 was later revised westward to terminate at a new major railway station called Beijing West railway station and Line 9 taking over servicing Fengtai. When Beijing West railway station started construction in the early 1990s space was set aside for a subway station allowing Cross-platform interchange for the future Lines 7 and 9. By 1993 the planned section of Line 6 heading to Jiaohuachang was revised as an eastern extension of Line 7, forming the alignment built today.
Line 7 was originally slated to have 15 stations, from the Beijing West railway station to Baiziwan. A revised plan approved by the Planning Committee of the Beijing Municipal government called for 21 stations over 23.7 km (14.7 mi), ending in Jiaohuachang.
In 2013, planners revised the design of Line 7 from using the standard 6 car trains to 8 car trains after performing a detailed transport study of the Fatou area. Fatou's population projections were upgraded from 100,000 to 220,000 people and be a significant employment hub in the future. Planners decided that 6 cars trains would have insufficient capacity for the new demand projections. Line 7 was originally planned to use 1500 V DC overhead lines to power the longer subway trains. However, the already completed platforms at Beijing West railway station assumed the line would use a 750 V DC 3rd rail system like Beijing's legacy subway lines and built with vertical clearance for such. The line ultimately used a 1500 V DC 3rd rail system as a compromise.
In 8 July 2022, an EIA document regarding Phase III construction of Beijing rail transport system (2022–2027) announced the Phase III of Line 7, from Beijing West Railway station to Wanshousi, it will be a 6.4 km long section with 4 new stations. These are confirmed in the tender announcements published on 8 July 2024.

## History
### Phase 1

Construction began in January 2010. It started test runs in September 2014 with full operation beginning on December 28, 2014.

### Eastern extension (Phase 2)

The eastern extension runs through Chaoyang and Tongzhou Districts. The extension adds 9 new stations and 16.6 km (10.3 mi) of new line. The extension is fully underground. It was opened on December 28, 2019. Universal Resort station opened on August 26, 2021.
