context_page_description: Line 6 of the Beijing Subway is a rapid transit rail line in Beijing. The line runs from Jin'anqiao in Shijingshan District to Lucheng in Tongzhou District. It serves important residential areas such as Changying, Chaoqing, and Dingfuzhuang, in addition to important commercial and business areas such as Financial Street, Beijing CBD and the sub-administrative center in Tongzhou District. Like Line 7, Line 6 provides relief to the parallel Line 1, which is the second most used subway line in Beijing, after Line 10. Line 6 is the second longest subway line in Beijing. A complete journey from end to end takes about an hour and 25 minutes on a local train and express trains reducing end to end travel time by 7 minutes.
  Line 6 uses 8-car size B train sets accommodating 1,960 people.
  The trains are capable of reaching the speed of 100 km/h. Stations to the east of the 3rd Ring Road to Tongzhou are more widely spaced, the furthest being 4 km apart. Line 6 also has the deepest station in the network, Dongsi station, which is 34 meters underground. The line uses 1500 V overhead catenary as opposed to 750 V third rail used on other lines.
context_section_description: In Phase II, which opened in 2014, Line 6 was extended further east by about 12 km (7.5 mi) through seven stations from Caofang to Lucheng in Tongzhou New Town. Like Phase I, the Phase II track is entirely underground. 
  The extension was designed to have express and local services using passing tracks at select stations. However, due to a shortage of rolling stock, express services have yet to be implemented when the Phase II opens in 2014. In 2018, the government announced that sufficient rolling stock had arrived to begin implementing an express service. Express services started operating on March 31, 2020.
