Line 19 of theBeijing Subway (Chinese:北京地铁19号线;pinyin:Běijīng Dìtiě shíjiǔ hàoxiàn) is arapid transit line inBeijing. It is 20.9 km (13.0 mi) in length and has 10 stations.^[2] It is fully underground.^[3] Line 19's color is lavender.

Phase 1 of Line 19 begins atMudanyuan station inHaidian District and ends atXingong station inFengtai District.^[5] Phase 1 of Line 19 is 20.9 km (13.0 mi)^[2] in length with 10 stations.^[6] The line was envisioned as a major relief line for the overcrowdedLine 4 and more direct link to theBeijing Financial Street commercial area.

The line uses 8-car type A rolling stock.^[4][7]

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).^[8][9] 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.^[18] As of 2015, the line was renamed to Line 19^[19] with the first phase starting construction in 2016.^[5] The line opened on 31 December 2021.^[10] Four infill stations opened on 30 July 2022.^[11]

Phase 2 of Line 19, which is under planning, consists of a northern extension toChangping District. Additionally, there will be a branch line of the northern extension, which will serve the newQinghe railway station, a station on theBeijing–Zhangjiakou intercity railway.^[20] 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)".^[21]

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.^[22]

On 28 April 2024, Beijing Infrastructure Investment (BII) announced the northern extension and its branch, as well as southern extension.^[23] On 29 July, BII published the first EIA analysis to confirm these 3 parts.^[24]
