What the mapping says
VnExpress's technical explainer places the line's automatic control system at 'level 2.5' on a five-level automation scale, with a driver mode built in.
Caveat
A description in press reporting before opening, not an official grade-of-automation certification.

Sources carrying this claim

  1. VnExpress — Cat Linh-Ha Dong control technology
Claim 7 clm-47c61b8df88fdcb3 descriptive
trains run automatically in normal weather and switch to manual driving when rain makes the rails slippery

Mapping
mapped · no interpretation or interpolation added by this passport

Caveat
No claim-specific caveat recorded

Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Negative finding: both lines' own reporting consistently describes drivers aboard — manual fallback procedures on Line 2A, driver recruitment for Line 3 — and no reviewed source announces unattended operation or a date for it.
Caveat
An absence-of-evidence statement based on the sources reviewed for this entry, not an official commitment either way.

  1. VOV — sudden stop in rain, automatic to manual
  2. VOV — Nhon line recruits nearly 450 operations staff

mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's year-end report, relayed by the state information portal, states over 11.8 million passengers on Line 2A in 2024.

Claim 13 clm-bb53930c8d093580 quantitative
the 23,900 passengers per hour per direction quoted for the finished Line 3 is the signalling vendor's design capacity
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Alstom's own release states the integrated system 'can transport 23,900 passengers per hour per direction at full capacity' — a vendor design figure, quoted here precisely so it is not mistaken for ridership.

lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Line 2A's operating procedures assume a driver who takes over in bad weather; Line 3 recruited and trained its own drivers before opening. No reviewed source announces their removal.
Caveat
Negative finding based on the sources reviewed for this entry.

  1. VOV — sudden stop in rain, automatic to manual
  2. VOV — Nhon line recruits nearly 450 operations staff
