The line uses the medium-low speed magnetic levitation technology which can give a top speed of 105 km/h.[10][11] The actual speed of the line is 100 km/h (62 mph).[7]

Six-coach maglev trains were built by the Tangshan Railway Vehicle, a subsidiary of CRRC.[12] It is China's 3rd commercial maglev train in operation.[12] Line S1 is part of Beijing's attempts to tackle environmental problems caused by heavy car use, coal burning and fast urbanization by upgrading its urban rail systems.[12]

The Line S1 designation is a holdover from a defunct plan to build several suburban railway lines in Beijing. Line S1 was envisioned to reuse the Jingmen Railway connecting Cishou Si station to Mentougou District.[13] That plan was abandoned and the section between Pingguoyuan and Cishousi stations was replaced with Phase 3 of Line 6, and the other section was replaced with today's Maglev S1 Line.

When the Line S1 originally opened in 2017, it was not connected to the rest of the subway network. With the opening of Line 6 Phase 3 on 30 December 2018, passengers can transfer to Line 6 at Jin'anqiao.

Future DevelopmentEdit

Line S1 will be extended to Pingguoyuan. The extension is under construction. The elevated station for line S1 will open together with the Pingguoyuan Transportation Hub which will be finished in 2021.[5] In July 2021 a major bridge was completed and the opening of the extension is expected by the end of the year.[14]
