The Hanoi Metro (Vietnamese: Đường sắt đô thị Hà Nội, lit.

'Hanoi urban railway') is a rapid transit system in Hanoi, the capital city of Vietnam.

[6] The system will eventually consist of 8 lines with a total length of 318 kilometres (198 mi), and is initially expected to carry 200,000 passengers per day.

The Ministry of Transport (MoT) and the Hanoi People's Committee (HPC) will both be investors in the project.

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.

Line 2A was scheduled to commence operations in February 2019, before the holidays of Lunar New Year,[30] but was postponed for the sixth time as some station construction works remained incomplete.

Beginning in December 2020, Line 2A underwent a full-scale test run in order to check its safety before approval for commercial service.

In July 2018, the Hanoi Metropolitan Railway Management Board (MRB) announced that only 43% of the work for Line 3 had been completed, and the launch date of elevated section would most likely be delayed until early 2023.

However, in September 2022, the authorities requested to extend the deadline to 2025,[33] and increase the budget by a further VND1.9 trillion ($80.77m USD).

Furthermore, Ministry of Transportation has reported to National Assembly that the ministry has transferred the railway section from Yên Viên to Ngọc Hồi including Hà Nội railway station and Giáp Bát railway station to Hanoi People's Committee to implement Hanoi urban railway line (AKA Long Biên line) to feed the future North-South High Speed train since there will be a construction of the Northern terminus (AKA the Hà Nội High Speed train station which will be functioned as the new Hà Nội railway station) of North-South High Speed train at Ngọc Hồi on 151 hectares of land.

[37][38][39] [40] The line will be completed in 3 phases: The first 2 phases of Line 1 will have 16 stations: Yên Viên, Cầu Đuống, Đức Giang, Gia Lâm, Long Biên North, Long Biên South, Phùng Hưng, Hanoi, Thống Nhất Park, Bạch Mai, Phương Liệt, Giáp Bát, Hoàng Liệt, Văn Điển, Vĩnh Quỳnh, Ngọc Hồi Line 2 (Hoan Kiem Line): Nam Thăng Long - Trần Hưng Đạo (Phase 1) (Noi Bai Airport - Nam Thăng Long - Trần Hưng Đạo - Thượng Đình - Hoàng Quốc Việt) This section is 42 km in length, connecting Noi Bai Airport with the city center.

The route runs mainly on the current national track system, connecting the southern districts to the northern ones and Noi Bai airport (T2 terminal).

The CRRC supplied a total of 13 four-car train-sets in 2018, which are all currently stabled at a depot at Phu Luong, east of Yen Nghia.

The trains' exteriors are painted green, and the seal of the Hanoi Temple of Literature, which is the symbol Khue Van of Hanoi, is shown on the front of the train, and the line name “Cat Linh - Ha Dong” is displayed along the bottom in white.

The interior is wheelchair accessible, and also includes dedicated space and seating for senior citizens.

[43] The cyan, pink and grey of the exterior design symbolises rice seeding leaves and dragon fruit, some of the main products in Vietnam.

[44] Additionally, like Line 2A, the seal of the Hanoi Temple of Literature is displayed on the front of the train.

The ticket system will allow for connection between all routes and will be usable with other public transportation such as bus, taxi, etc.
