Line 28 of the Beijing Subway is a rapid transit line under construction in Beijing. It was formerly known as CBD line.
Construction started in July 2021.[1] It is planned to open in 2029.[2]
In August 2015, planning authorities proposed an underground automatic people mover (APM) line through the Central Business District (CBD).[4]
According to the most recent plan announced in August 2019, the line will run 8.877km (05.516miles), have 9 stations from Dongdaqiao to Guangqudonglu. The line was redesigned into a higher capacity light metro line, not an automatic people mover (APM).[5]
A feasibility study for the line was approved in October 2020.[6]
Construction started in July 2021.
It will use 6-car Type LB linear motor rolling stock, similar to the Capital Airport Express of Beijing Subway, and Guangzhou Metro's Line 4, Line 5 and Line 6.
