Line 18 of the Beijing Subway (Chinese: 北京地铁18号线; pinyin: běijīng dìtiě shíbāhào xiàn),[2][3] also known as the Line 13-18 temporary through service line,[4] is a metro line that serves the northern suburbs of Beijing, from Malianwa in the west in Haidian District to Tiantongyuandong in the east in Changping District. The line is 19.8 km (12.3 mi) long[1] with 11 stations, and has a stabling yard in Xiaoxinzhuang (小辛庄停车场). It currently does not feature an interchange with Line 13.[a] The line originally planned to open between Dongbeiwang and Tiantongyuandong at the end of 2025,[5][6][7] and open Shangdi Software Park and Malianwa in 2026, but due to the faster than expected construction progress, the entire section opened on December 27, 2025.[8][3]

Exit E (formerly Exit A2) of Huilongguan Dongdajie Station on Line 18 is expected to be completed in September 2025.
The construction period for the expansion project of the existing Dazhongsi Station on Line 13 to 8 train cars is tentatively scheduled to end in December 2027.

In April 2023, all 11 stations in the northern section of the Beijing Subway Line 13 split project started construction.[9] As of January 2025, most of the stations in the 8-car lengthening project of the existing Line 13 (Xierqi Station to Dazhongsi Station) were still in a state of fencing the construction site, which meant construction had not started substantively or the construction progress was slow, with the tentative construction period expected to last until December 2027. In addition, the construction progress of the underground Longze Station on the east side of the existing Longze Station was also slow, with the current tentative construction period also lasting till the end of 2027.[10] The tunnel entry point south of Dazhong Si Station in the southern extension has not yet made major progress due to the demolition of existing buildings. Due to land acquisition issues, construction of the new Chegongzhuang Station was delayed until April 2024.[11] Affected by the above factors, from December 2025 to December 2027, the new northern section of the Line 13 split project will be operated independently as a new line. The new line was once tentatively called the "Yizi line of Line 13".[12][13][14]

In June 2025, CRCC confirmed to use the name Line 13-18 north section through line (13-18北段贯通线).[4][15][16] As of July 2025, all stations from Malianwa to Tiantongyuandong have been topped out and all tunnel sections were broken through.[17] In September the same year, the line confirmed the adoption of the name of Beijing Subway Line 18 and began a no-load trial operation for no less than three months, with plans to open for operation by the end of 2025.[3]

On December 26, 2025, the Beijing Municipal Transportation Commission and the Municipal Major Office confirmed that Line 18 was to open the following day.[8]

Initial operation

On December 27, 2025, Line 18 officially opened. On December 29 the same year, as the first working day after the opening of Line 18, nearly 20,000 people entered and exited Line 18 during the morning rush hour (7:00-9:00).[18]

According to the news forecast released by Beijing Radio and Television Station and other municipal media, in the future, after the official completion of the expansion project of Line 13, Line 13A will officially use the Line 18 name, whilst Line 13B, together with the stations west of Longzexi of Line 18 opened in 2025, will continue to use the Line 13 name. However, it remains to be seen how the actual use of the Line 18 name will be in the future.[21]

Below is the tentative route of Line 18 if it operates in the future according to Line 13A:
