Vietnam Launches $50B 303.5 km Five Hanoi Metro Lines

HANOI, VIETNAM – At a launch event attended by Prime Minister Le Minh Hung, Hanoi authorities began works on five new metro lines with an announced total length of 303.5 km and an investment programme estimated at USD 50 billion. The lines—1, 2, 8, 10 and 14—cover the airport, historic centre, new eastern and western development areas, and a circular corridor. The launch shifts delivery from a project-by-project approach to a coordinated five-line package.

What Is the Full Scope of This Project?

The five new lines together total 303.5 km and are designed as one integrated metropolitan network rather than five standalone corridors. Line 1 is an 81 km north–south airport axis; Line 2 is a 56.5 km second north–south axis through Hoàn Kiếm; Line 8 is the longest at 91 km west–east through Ring Road 3; Line 10 is a 43 km circular line; and Line 14 is a 27 km east–west link to Ocean Park. However, the disclosed line-level lengths sum to 298.5 km, not the announced 303.5 km; no explanation was provided for the 5 km difference. The MRB did not specify whether the USD 50 billion estimate includes rolling stock, depots, land acquisition or financing costs.

Note: Independent verification of individual line completion dates and line-specific costs was not available at time of publication.

Key Project Data

How Does This Compare to Similar Projects?

At 303.5 km, the five-line package equals about 73% of Delhi Metro’s 416.5 km operational network, which has 303 stations across 12 lines (Source: Delhi Metro Rail Corporation, 2025). At the stated USD 50 billion estimate, the average capital cost would be about USD 165 million per route-km. By contrast, Hanoi’s overall planned 979 km network would be more than double Delhi’s current operational length. Regional demand conditions support the investment: UIC recorded a 7% increase in rail passenger traffic in 2024 compared with 2023 (Source: UIC, 2025), and South Korea’s railway system sector is projected to grow at a 4.7% CAGR through 2036 (Source: Future Market Insights, 2025). Comparable data for a single simultaneous five-line metro civil works package in another Southeast Asian capital was not publicly available at time of publication; Delhi’s network is the closest large-network benchmark.

Regional technology contracts continue to move in parallel: Alstom is supplying metro cars and CBTC signaling for Mumbai Metro Line 4, and Hitachi Rail is delivering signaling and SCADA systems for Taipei Keelung MRT (Source: Alstom, 2025; Source: Hitachi Rail, 2025).

Editor’s Analysis

Hanoi’s switch to a five-line EPC envelope compresses delivery timelines but concentrates execution risk in a single consortium; the absence of line-level completion dates weakens schedule accountability. The 5 km discrepancy between the announced total length and the sum of official line lengths should be clarified by MRB before financing benchmarks are set. If Hanoi reaches roughly 500 km by 2035, it would move from two operational lines to half of its planned 979 km network in about a decade, at a pace faster than most Southeast Asian metro build-outs; this aligns with UIC’s 2024 traffic growth signal and could shift road-dependent travel patterns (Source: UIC, 2025).

FAQ

Q: What is the total length of the five new Hanoi metro lines?
A: The announced total is 303.5 km across Lines 1, 2, 8, 10 and 14. The disclosed line-level lengths sum to 298.5 km; no explanation has been given for the difference.

Q: How much will the Hanoi metro expansion cost and who is responsible for construction?
A: The investment programme is estimated at USD 50 billion. The EPC consortium is Vinhomes and VinSpeed High-Speed Railway Investment and Development, working with Hanoi Metro’s management board.

Q: When will the five new metro lines be operational?
A: Hanoi’s wider plan targets about 500 km of urban rail by 2035 and the full 979 km network between 2035 and 2045. Individual completion dates for the five newly launched lines have not been officially confirmed.
