Home/Metro, train & bus

Metro, train & bus

Since October 2024 both terminals have their own underground metro station. It has changed airport travel in Mumbai completely.

Short version Take Metro Line 3. Both terminals have their own underground station, the whole line is air-conditioned, fares run ₹10–₹80, and it is the only way into Mumbai that traffic and monsoon cannot touch.

Metro Line 3

Stations at both terminals. Aarey to Cuffe Parade, entirely underground.

Suburban rail

Vile Parle for T1, Andheri for T2. Cheap, but not with luggage.

BEST AC buses

The big change

Metro Line 3 — the Aqua Line

Mumbai's first fully underground metro: 33.5 km and 27 stations from Aarey JVLR to Cuffe Parade. Three of those stations sit in the airport complex, and two of them serve the passenger terminals directly.

StationServesOpenedNotes
CSMI Airport T2Terminal 27 Oct 2024 Exit 1A connects to the terminal. Concourse on L1, platforms on L2.
CSMI Airport T1Terminal 17 Oct 2024 Two entry/exit gates.
Sahar RoadSahar cargo area7 Oct 2024 Between the two airport stations — not the station for either terminal.

Getting from the T2 station to the terminal

When the line opened in October 2024, the T2 station sat around 500 metres from the terminal along poorly signposted public roads — a genuine complaint in the first months. A direct connecting bridge from Exit 1A opened in August 2025 and cut the walk to roughly 100 metres.

Whether trolleys can be taken the full length of that link is not clearly documented, so if you are travelling with several heavy cases, factor that in.

Hours and frequency

Published sources differ. Station data shows first trains around 05:51 on weekdays and around 06:21 on Sundays, with last trains close to 23:40. Frequency is roughly every 3.5–4 minutes at peak and 8–12 minutes off-peak.

Check before an early or late flight If your flight is before 07:00 or lands after 23:00, assume the metro will not be running and plan a taxi.

Older lines

Line 1 is no longer the answer

Before October 2024, the closest metro stations to CSMIA were Airport Road and Marol Naka on Line 1, the elevated Versova–Andheri–Ghatkopar route. Despite its name, Airport Road adjoins neither terminal — it is roughly 2 km from T1 and 3 km from T2, needing a cab or auto at the end.

Marol Naka is now an interchange with Line 3, but the two lines are not physically connected: there are no lifts or escalators between them, so you must exit one system and buy a separate ticket to enter the other.

If you are heading to or from the airport, take Line 3 from the terminal stations and ignore Line 1 entirely.

Line 7A — coming

A 3.4 km extension of the Red Line from Andheri East into CSMIA, with two stations: Airport Colony (elevated) and an underground CSMIA station built parallel to Line 3's.

Both tunnels broke through by July 2025 and the line was reported 61% complete. The projected opening is December 2026 — a projection, not a promise. It would bring Dahisar East to the airport down from about 90 minutes to 50, without changing trains.

Suburban rail

The local trains

Mumbai's suburban network is astonishingly cheap and astonishingly crowded. Neither terminal has a station of its own.

TerminalNearest stationLineDistanceConnecting bus
T1Vile Parle (East)Western~1.7 kmBEST route 312
T2Andheri (East)Western + Harbour~6 kmBEST routes 321, 308
Do not attempt this with suitcases Mumbai locals have no luggage provision and boarding at peak with a large case is impractical and genuinely unsafe. Avoid roughly 08:00–11:00 and 17:30–21:00 entirely.
When it does make sense Hand luggage only, travelling off-peak, and heading somewhere Line 3 does not go — Borivali, Virar, or Panvel via the Harbour Line. Second-class fares start around ₹5–10; tickets via the UTS app or a station counter.
Buses

BEST airport routes

Air-conditioned express services run around the clock from both terminals. They are slower than the metro but they take luggage without complaint and cost a fraction of a taxi.
