Hanoi Metro
The Hanoi Metro () is a rapid transit system in Hanoi, the capital city of Vietnam. Owned by Vietnam Railways and operated by Hanoi Metro Company (HMC), it is the first operational rapid transit system in Vietnam. The first line (Line 2A - Cat Linh Line) opened to service on 6 November 2021. The system includes elevated and underground sections. Another line (Line 3 - Van Mieu Line)  is under construction, and was expected to commence operations at the end of 2022, however, in September 2022, the authorities requested to extend the deadline to 2025, and increase the budget by a further VND1.9 trillion ($80.77m USD). The system will eventually consist of 8 lines with a total length of , and is initially expected to carry 200,000 passengers per day. Upon opening, daily ridership was at 12,000. History

Pre-planning
As the capital city of Vietnam, Hanoi's population is growing rapidly. As of 2010 (the year when construction started on the first line), Hanoi's population was around 6,910,000. Hoàn Kiếm District and Ba Đình District are the districts with the highest population density. The government expects the population of Hanoi to increase up to 8,000,000 by 2030. The growing population would affect the city's operation and development. To solve this issue, the Vietnamese government and the Hanoi People's Committee proposed to build an urban rail transit system, which was first proposed in the late 1990s. In 1998, the Vietnamese government revised and agreed the “Hanoi Capital to 2020 Master Plan” which suggested that Hanoi prioritise the building of a rail transit system, with a target to build 5 lines. The "Overall Plan for the Development of Vietnam's Railway Transportation Industry to 2020", released in 2002, and the "2005-2010 Economic and Social Development Plan for 2006-2010", released in 2006, both suggested the same and aimed to finish the metro system by 2010. Construction
The start of construction was delayed continually as the government first required the consultant companies from China, France and Japan, such as SYSTRA and Japan International Cooperation Agency, to finish feasibility studies which ran from 2004 to 2007. These three companies suggested the Hanoi government build a network consisting of 6 lines. Finally, in 2008, the Vietnamese government approved the construction of the suggested lines, which they divided into several phases. The Phase 1 includes Line 2A and Line 3 construction. The construction of Line 2A was started on 2011, and the construction of Line 3 was started on 2010. Network
According to the Prime Minister's decision approving the transport development of Hanoi by 2030 and vision to 2050 (519/QD-TTg dated 31 March 2016), the Hanoi Metro system will consist of 8 lines, including elevated and underground sections. The Ministry of Transport (MoT) and the Hanoi People's Committee (HPC) will both be investors in the project. Phase 1 includes Line 2A and Line 3, Line 2A is in service, and Line 3 is currently under construction. Line 2A (Cat Linh Line): Cat Linh - Ha Dong 

The  line, consisting of 12 stations (all elevated), and connecting the districts Dong Da, Thanh Xuan and Ha Dong, will be the first operational line in the metro system. This line is constructed using Official Development Assistance (ODA) from China with a total investment of US$868 million. The China Railway Sixth Group is the EPC (Engineering, Procurement and Construction) contractor for the project, and the Ministry of Transport (Vietnam) is an investor. The construction was started on 10 October 2011 and was initially targeted to begin operations in 2016. In 2016, it was announced that the completion date was to be pushed back to early 2018. However, due to funding and land acquisition issues, construction wasn't completed until September 2018. Following completion, the pilot run and testing was conducted from September to December 2018. Line 2A was scheduled to commence operations in February 2019, before the holidays of Lunar New Year, but was postponed for the sixth time as some station construction works remained incomplete. Transport Minister Nguyen Van The had hopes that operations would begin in April 2019. On 30 April 2019, a representative from the Railway Project Management Board informed the press that the line was not yet operational, the reason stated being that the system had not yet been issued with a safety certificate and it had not been accepted by the State Acceptance Council. By the deadline of 30 April 2019, the General Chinese Contractor had not completed some stations, depot areas, escalator roofs for stations, drainage connections for Ring Road Station 3, landscaping, trees, electricity and ticketing systems. After multiple delays, the trial run was restarted on 28 October 2019, to last for 20 days. Beginning in December 2020, Line 2A underwent a full-scale test run in order to check its safety before approval for commercial service. Line 2A opened to the public on 6 Nov 2021. Line 3 (Van Mieu Line): Nhon - Hanoi Station Section 

The Hanoi Metro Rail System Project (Line 3: Nhon - Hanoi Station section) is in line with the Prime Minister's decision approving the transport development of Hanoi by 2030 and vision to 2050 (519/QD-TTg dated 31 March 2016). The project has the Hanoi Metropolitan Railway Management Board, French government, Asian Development Bank, and European Investment Bank as the investors, and will be built in two phases. Phase 1 is  long in total and consists of 12 stations, with  elevated and  underground, and will serve residents from districts such as Nam Tu Liem, Bac Tu Liem, Cau Giay, Ba Dinh, Dong Da, and Hoan Kiem. Construction for Line 3 began in 2010 and was initially targeted to commence service in 2018. However, in 2017, it was announced that the construction would not be complete until 2021, and that the operation start was deferred to 2022. In July 2018, the Hanoi Metropolitan Railway Management Board (MRB) announced that only 43% of the work for Line 3 had been completed and that the launch date would most likely be delayed until early 2023. The line was further delayed in September 2022 when the authorities announced that they expected the line to open in 2027. Future plans
