Line 2A, Hanoi Metro (Cát Linh–Hà Đông), also known as Cát Linh line, is an elevated mass transit railway line under testing and the part of the Hanoi Metro network, is expected to start operations in 2019. The 12 station line starts at Cat Linh in Dong Da District, passes through Thuong Dinh in Thanh Xuân District and ends at Yen Nghia in Ha Dong District. It will be the first rapid transit line to operate in Vietnam.

Construction of the 13.1-km line started on October 2011 and was initially scheduled to be completed by 2013. The completion has been delayed due to several hurdles including finalizing funding from the government of China. The original cost estimate of $552.86 million has also ballooned to more than $868 million. Most of the funding for the project is financed by preferential loans from the Export Import Bank of China.[1] The rest of funding is from the Vietnamese government.[2]

Construction was finally completed in fourth quarter of 2018. Operational tests have been finished on 30 December 2018.[3][4]


The stations are built and designed with the concept of station variety. Each station has a distinct color, in which La Khe, the sample station, is light green. All stations have curvy roofs, suitable for hot, humid and rainy climate of Vietnam and consistent with the southeast Asian architecture. The roofs are covered with light-absorbing, wind-protection and radiation-proof materials. Especially Cat Linh Station is specially designed with modern and neighborhood-multifunctional style.

Inside the stations is modern equipment system such as lifts, escalators, stairways, security cameras, people-with-disabilities supporting device, automatic fare collection system, ventilation system, Emergency exits are designed according to international standards to ensure maximum safety for passengers.
