Line 19 of the Beijing Subway (Chinese: 北京地铁19号线; pinyin: Běijīng Dìtiě shíjiǔ hàoxiàn) is a rapid transit line in Beijing. It is 20.9 km (13.0 mi) in length and has 10 stations. It is fully underground. Line 19's color is lavender.
The trains have a maximum speed of 120 km/h (75 mph). However the speed limit of the first phase, which runs under the dense city center is 100 km/h (62 mph). Phase II extensions north and south run through suburban areas and will be built to more generous alignments allowing for 120 km/h (75 mph) operations.
It was reported in February 2012 as one of six new lines under planning by the city's public transit planning authorities. As of 2015, the line was renamed to Line 19 with the first phase starting construction in 2016. The line opened on 31 December 2021. Four infill stations opened on 30 July 2022.
Future development
Phase 2 of Line 19, which is under planning, consists of a northern extension to Changping District. Additionally, there will be a branch line of the northern extension, which will serve the new Qinghe railway station, a station on the Beijing–Zhangjiakou intercity railway. On 11 January 2022, the second phase of Line 19 was listed as one of the 10 construction projects in the "Beijing Rail Transit Phase III Construction Plan (2022-2027)".
On 8 July 2022, an EIA document regarding Phase III construction of Beijing rail transport system (2022–2027) expanded the phase 2 planning. The northern extension will start from Mudanyuan and run to Life Valley as a 17.6 km (10.9 mi) long section with 6 new stations. A branch of the northern extension will run from Shangqingqiao South to Qinghe railway station for 6.8 km (4.2 mi) with one new station. Additionally, a southern extension was announced from Xingong to Haizijiao as a 12.6 km (7.8 mi) long section with 6 new stations along with a branch of the southern extension from Xinmeiti Chanye Jidi to Shengwu Yiyao Jidi West which will be 17.4 km (10.8 mi) long with 7 new stations.
On 28 April 2024, Beijing Infrastructure Investment announced the northern extension and its branch, as well as southern extension. On 29 July, BII published the first EIA analysis to confirm these 3 parts.
