The Ba Tong Line derives its name by combining the first character of Bawangfen (八王坟), another name for Sihui, and Tongzhou (通州), the eastern suburban district of Beijing which the line serves.

The Ba Tong Line is mainly above ground with only 3.8 km section is underground[4] and runs 23.4 km (14.5 mi)[3] from the Si Hui in the west to Hua Zhuang in the east. The colour of Ba Tong Line that is shown on maps, like that of Line 1, is red.

The line tends be very crowded during rush hour. To alleviate this headways were reduced and skip-stop services were introduced during rush hour.

History

Phase 1

Construction of the Ba Tong Line began on December 28, 2001 and the line opened on December 27, 2003.

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.[7] However, during peak hours sections the line still operates above 100% capacity.[7]

Southern extension (Phase 2)

There are 2 stations on the southern extension: Hua Zhuang station and Universal Resort station (both are transfer stations with the eastern extension of Line 7).[8] The extension is 4.5 km in length,[9] including 3.8 km underground section.[10] Hua Zhuang station was opened on December 28, 2019.[11] Universal Resort station will open simultaneously with the opening of Universal Beijing Resort[12] (in May 2021[13]).

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(E) or Si Hui.[15] 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.[16] 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.[17] Completion of this project is scheduled for late 2022.[18]
