Current status (October 2026)

  • Phase 1: Gaimukh – Cadbury Junction (about 10.5 km, 10 stations including Line 4A) has finished trial runs, which began between Gaimukh and Vijay Garden in September 2025 and later covered the whole stretch. On 26 October 2026, Transport Minister Pratap Sarnaik said this first phase will open in December 2026, later than the earlier Diwali target. Final safety approval for passenger services is still awaited.
  • Safety testing: RDSO certified the trains, track and signalling on 2 June 2026. In August 2026 the Commissioner of Metro Rail Safety (CMRS) cleared the rolling stock and inspected the temporary pit line at Gaimukh.
  • Trains: on 14 October 2026, Alstom unveiled the first of the line’s own 39 driverless six-car Metropolis trains at its Sri City factory, built in 14 months. They run at up to 80 km/h and have wheelchair spaces and bicycle racks. Until enough of these trains are delivered and tested, the first services are expected to use interim trains from the Charkop depot (used on Lines 2A, 7 and 9).
  • Depot: the Mogharpada depot on Ghodbunder Road is not ready; trains will be stabled and serviced at Gaimukh until it is.
  • Rest of the line: Cadbury Junction to Wadala is still under construction, with no firm opening dates.

About Metro Line 4

Route explained

From Kasarvadavali, Line 4 runs south along Ghodbunder Road to Cadbury Junction, through Thane to Mulund, and then along LBS Marg through Bhandup, Kanjurmarg, Vikhroli and Ghatkopar. It ends at Bhakti Park near the Wadala Truck Terminal. Line 4A adds two stations north to Gaimukh.

Why Line 4 matters

Thane to Mumbai traffic today relies on the Central Railway locals and the congested Eastern Express Highway. Line 4 gives Ghodbunder Road and LBS Marg their first rail link, with connections to four other metro lines and the Monorail.

Frequently asked questions

Is Mumbai Metro Line 4 open?

Not yet. The first section, about 10.5 km from Gaimukh to Cadbury Junction in Thane, has finished trial runs and safety testing. The state government now expects it to open in December 2026, subject to final safety approval. No exact opening date has been announced yet.

What is the route of Metro Line 4?

Line 4 (Green Line) runs from Wadala in central Mumbai to Kasarvadavali on Ghodbunder Road in Thane, along the Eastern Express Highway and LBS Marg. Line 4A extends it 2.88 km further to Gaimukh.

How many stations does Line 4 have?

30 elevated stations between Kasarvadavali and Bhakti Park (Wadala). Two stations in the original plan, Amar Mahal Junction and Suman Nagar, were dropped by MMRDA.

Which stations open first on Line 4?

Phase 1 covers ten stations: Gaimukh, Gowniwada, Kasarvadavali, Vijay Garden, Dongripada, Tikuji-ni-wadi, Manpada, Kapurbawdi, Majiwada and Cadbury Junction. The first two are on Line 4A.

Where can I change from Line 4 to other metro lines?

Planned interchanges include Line 6 at Gandhi Nagar (Kanjurmarg), Line 1 near Ghatkopar, Line 2B at Siddharth Colony, the Monorail at Bhakti Park (Wadala) and Line 5 at Kapurbawdi. Most of these will only work once the relevant sections open.

What will the fare be on Line 4?

Fares have not been announced. Other MMMOCL-run lines charge distance-based fares starting at ₹10.

When will Line 4 reach Wadala?

The line will open in stages southwards from Thane. MMRDA has not announced firm dates for the Cadbury Junction – Gandhi Nagar and Gandhi Nagar – Wadala sections.

Who operates Line 4?

MMRDA is building the line. Safety clearances for the first section have been issued to MMRDA and Maha Mumbai Metro Operation Corporation (MMMOCL), which will run the trains.

What trains will run on Metro Line 4?

Line 4 and 4A will use 39 driverless six-car Metropolis trains from Alstom, supplied under an L&T–Alstom contract. The first train was unveiled on 14 October 2026. Until enough of them are delivered and tested, the first services are expected to use interim trains from the Charkop depot.

Why has Line 4 been delayed?

The line was first due in 2022. Delays came from land and court issues, a cancelled train order, and in 2026 a fatal parapet collapse at Mulund that held up safety work by about two months. The Mogharpada depot is also not ready, so trains will be maintained at a temporary pit line at Gaimukh.
