In 2007, the "Shenzhen City Rail Transit Construction Plan (2011 to 2020)" was publicly announced for the first time, which included the plans for Line 11. The plan calls for an express metro line running along the western coast of Shenzhen with through services to Dongguan, Guangzhou and beyond via the Guangzhou–Shenzhen intercity railway which was then envisioned to be an intercity metro line. In December 2008, a ground breaking ceremony was held for the project, attended by Party Secretary Wang Yang and Governor Huang Huahua. However, design changes started immediately after due to disagreements on how  to integrate the metro project with the intercity line. Subsequently, the project was postponed. In July 2010, China Railway Minister Liu Zhijun and Guangdong Executive Vice Governor Zhu Xiaodan held talks to speed up railway construction in Guangdong. The result was a new plan to construct a Pearl River Delta Metropolitan Region intercity railway network. The Guangzhou–Shenzhen intercity railway was redesigned from a rapid transit line to a regional rail line and will no longer enter the central area of Shenzhen. Instead the Guangzhou–Shenzhen intercity railway shall terminate at station with interchange for Line 11 but no through  services. Stations. Planned extension. Line 11 is planned to have an east extension to Hongling South Station. Additional proposals include a northern extension into Chang'an, Dongguan with transfers to Dongguan Rail Transit and through train service with the proposed Shenzhen Metro Line 14. Rolling stock.

On 4 July 2015, the first train completed eight months of commissioning work, and 10 trains have been delivered from CRRC  Zhuzhou as of March 2016. The maximum train capacity is 2564 people. Business Class. Business Class has transverse seating and curtains for comfort and luggage racks for airport passengers.

Standard class carriages are marked by light grey floor tiles and white panels above the doors. Fares. Two kinds of fares are charged on Line 11. In standard class, the  fare is equivalent to other metro lines. Business Class is three times as expensive as standard class. Standard class fares range between 2 and 10 yuan, with Business Class ranging between 6 and 30 yuan. Because of the possibility of transfers, this makes the maximum possible fare on the Shenzhen Metro 35 yuan. Business Class can be accessed through placing the Shenzhen Tong on a validator or through purchasing a yellow token (standard tokens are green). 11% of passengers travel by Business Class.
