In 2012, traffic on Ba Tong Line was relieved by the opening of the parallel Line 6, with a 12.14% decrease in daily ridership and a 10–20% reduction in flow during rush hour. However, during peak hours sections the line still operates above 100% capacity.

Southern extension (Phase 2)

Future Development

Through operations with Line 1

In 2010, a CPPCC member Chen Dingwang, proposed that services on Line 1 and the Ba Tong Line should directly link, with through operations, reducing travel times and removing the unnecessary forced transfers at Si Hui Dong or Si Hui. However, the Beijing Subway responded that Line 1's and Ba Tong's signal systems are completely different, so through-operation will be more difficult to achieve from an engineering standpoint. As of 2016, preliminary design and feasibility studies are underway to allow for through operations between Line 1 and Ba Tong. On June 12, 2020, the project of the through operation of Line 1 and Ba Tong line was approved by Beijing Development and Reform Commission. Completion of this project is scheduled for 2021.
