Vietnam's first two metro lines both run in Hanoi. The Chinese-built Cat Linh–Ha Dong line opened in November 2021, ten years after construction began, its cost rising from $553 million to about $868 million, with 77% covered by Chinese ODA loans. The Alstom-fitted elevated section of the Nhon–Hanoi Station line followed in August 2024 — 8.5 of the planned 12.5 kilometres, with the four underground stations still unfinished. Both lines run automated train control — Alstom's Urbalis 400 CBTC on the Nhon line, a system VnExpress described as 'level 2.5' automation on Cat Linh–Ha Dong — yet a driver sits in every cab: the operator's director has explained that trains run automatically in normal weather and switch to manual driving when rain makes the rails slippery, and the Nhon line recruited hundreds of operations staff, train drivers included, before opening. No source reviewed here names a date for the day nobody is on board.

what does this mean?The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →
Run byHanoi Metro Company (Hanoi Railway One-Member Co., Ltd), owned by the Hanoi People's Committee
Scale🏙️ City-wide
Cost≈$868M (Line 2A alone, up from $553M)
FundingChinese ODA loans (~77% of Line 2A); French government, AFD, EIB and ADB (Line 3)

📊 Impact

Hanoi Metro reported 11.8 million passenger trips on Cat Linh–Ha Dong in 2024 — about 32,900 a day, roughly 10% more than in 2023 — and nearly 14.2 million on the Nhon line's elevated section in its first two years. These are the operator's own counts, not an independent audit; the 23,900 passengers per hour per direction quoted for the finished Line 3 is the signalling vendor's design capacity, not demand.

🎓 Lesson

Equipment for automatic operation is a procurement fact, not an operations fact: both of Hanoi's lines can drive themselves, and both still roster a driver in every cab with no announced date for their removal.
