Line 6 was originally conceived in 1973 as a "pan-handle" shaped route incorporating the central sections of today's Lines 6 and 7.{{cite book|author=北京市地铁运营有限公司|title=北京地铁发展史|location=北京|publisher=北京出版社|date=December 2011|pages=162–164}} 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.{{cite book|author=北京市地铁运营有限公司|title=北京地铁发展史|location=北京|publisher=北京出版社|date=December 2011|pages=222–225}} 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.{{cite book|author=施仲衡 主编|title=地下铁道设计与施工|publisher=陕西科学技术出版社|location=西安|pages=44–45|date=1997}} 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.{{cite journal|title=地铁北京西站改造大规模病害治理技术|author=荆永波|journal=铁道建筑技术|issue=7|pages=61–65}} 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.{{cite book|author=北京市地铁运营有限公司|title=北京地铁发展史|location=北京|publisher=北京出版社|date=December 2011|pages=355}}

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 {{convert|23.7|km|abbr=on}}, ending in Jiaohuachang.{{cite web|date=2008-08-07|script-title=zh:"轨道交通7号线规划方案通过专家评审" 轨道协调组|url=http://www.bjghw.gov.cn/zwgk/list.asp?id=8304&column_id=19&column_layer=020009010010010019&title_name=%B9%EC%B5%C0%BD%BB%CD%A87%BA%C5%CF%DF%B9%E6%BB%AE%B7%BD%B0%B8%CD%A8%B9%FD%D7%A8%BC%D2%C6%C0%C9%F3|language=zh-hans}}{{dead link|date=December 2017|bot=InternetArchiveBot|fix-attempted=yes}}

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.{{Cite web |url=http://www.bjjtw.gov.cn/xxgk/dtxx/201411/t20141119_97206.html |title=北京市交通委员会 |access-date=2015-09-25 |archive-url=https://web.archive.org/web/20150926094804/http://www.bjjtw.gov.cn/xxgk/dtxx/201411/t20141119_97206.html |archive-date=2015-09-26 |url-status=dead }}
