The Batong Line of the Beijing Subway () is a surface level rapid transit rail line in eastern Beijing.
 It extends Line 1 further east from Sihui to the suburbs in Tongzhou District.
 The Batong Line derives its name by combining the first character of Bawangfen (八王坟), another place name for Sihui, and Tongzhou (通州) the eastern suburban district of Beijing which the line serves.

Beijing Jockey Club (BJC), located in the Tongzhou District of Beijing and covering an area of 1.6 square kilometres, was one of the largest international standard horse-racing clubs in Asia.
 In 2001, with the approval of the state government, the club embarked on thorougbred racing as a major business.
 The club bred over 2,000 thoroughbred horses.
 However, the Tongzhou racecourse was shut down on 23 October 2005.
 In the following month, over 600 horses were destroyed.
 The reason for the closure and the cull appears to have been loss of revenue, following the decision of the Chinese government not to allow gambling on horseracing.
 The club had previously operated a Tote system in 2003, apparently supported by the local government, but this had to be suspended in the 2004-05 season, following the government decision.
 The club is shut down.
