Batong line

The Batong Line of the Beijing Subway (Chinese: 北京地铁八通线; pinyin: Běijīng dìtiě Bātōng xiàn) is an east–west rapid transit line in eastern Beijing. It extends Line 1 further east from Sihui in Chaoyang District to Universal Resort in Tongzhou District. Through operation with Line 1 started on August 29, 2021.

The Batong 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 Batong Line is mainly above ground with only 3.8 km (2.4 mi) section is underground and runs 23.4 km (14.5 mi) from Sihui in the west to Universal Resort in the east. The color of the Batong Line that is shown on maps, like that of Line 1, is dark red.

The line tends to be very crowded during rush hour. To alleviate this headways were reduced and express services were introduced during rush hour in early 2020. However, these express services were removed with the start of through operation with Line 1 in mid 2021.

The first east-bound train departs Sihui at 6:00 am. The first west-bound train departs Huazhuang at 5:16 am. The last east-bound train leaves Sihui at 11:40 pm. The last west-bound train leaves Huazhuang at 10:56 pm.

The Batong Line follows the Beijing-Tongzhou Expressway eastward from Sihui to Guǎnzhuang. Between Gaobeidian and Guǎnzhuang, the Batong Line and its stations are built into the highway's median. At Bali Qiao, the Batong Line turns to the southeast and follows the Jingtang Road to Tu Qiao, which is located just inside the Tuqiao Bridge exit on the eastern 6th Ring Road. From there, the line turns and follows the 6th Ring Road south and west to Huazhuang and Universal Resort.
