Thane – MMR | October 2025
A Spine That Transforms Mumbai’s Commute Map
Three metro corridors are merging into a continuous north–south network connecting Gaimukh (Thane) with Colaba (South Mumbai).
Together, Metro Line 4 (Wadala – Kasarvadavli), its northern extension Line 4A (Kasarvadavli – Gaimukh), and the underground Line 11 (Wadala – CSMT – Colaba) form the most transformative mobility corridor in the Mumbai Metropolitan Region (MMR).
When complete, commuters will travel from Gaimukh to Colaba with a single interchange at Wadala — the junction between the elevated Green Line (4 / 4A) and the underground Line 11.
The Three Lines in Detail
Line 4 – Wadala to Kasarvadavli (32.32 km | 30 stations)
An elevated corridor linking Wadala → Ghatkopar → Bhandup → Mulund → Majiwada → Kapurbawdi → Manpada → Tikuji-ni-Wadi → Dongari Pada → Vijay Garden → Kasarvadavli.
Civil work began in 2018 under MMRDA and now dominates Thane’s skyline.
Line 4A – Kasarvadavli to Gaimukh (~2.88 km extension)
Extends the Green Line north from Kasarvadavli to Govniwada and Gaimukh, creating the new northern terminus on Ghodbunder Road. DPR approved in 2018.
Line 11 – Wadala to CSMT to Colaba (~17.4 km | fully underground)
Implemented by MMRCL, it links Bhakti Park / Anik Depot → Byculla / Nagpada / Bhendi Bazar → CSMT → Fort → Gateway of India / Colaba, completing north–south continuity through an interchange at Wadala.
Trials Underway in Thane
The first Green Line trial runs began on 22 September 2025, marking a milestone for Mumbai’s metro network.
Tests cover the ≈10.5 km stretch from Gaimukh to Cadbury Junction, including stations at Vijay Garden, Kasarvadavli and Manpada.
A phased opening is targeted by the end of 2025, beginning with four stations and extending to Cadbury Junction by April 2026, subject to clearance from the Commissioner of Railway Safety (CRS).
Thane commuters will therefore ride their first operational segment months before the entire Wadala corridor is ready.
Connectivity Logic and Commuter Impact
- Thane & Suburbs: Lines 4 and 4A create a grade-separated corridor from Gaimukh through Kasarvadavli, Kapurbawdi and Majiwada to Wadala, reducing road dependence and travel fatigue.
- South Mumbai: Line 11 links Colaba, Fort and CSMT to the metro grid for the first time, offering air-conditioned relief from road congestion.
The projected end-to-end journey (Gaimukh → Colaba, with one interchange at Wadala) is approximately 75 minutes, a significant improvement over the current two-plus hours by car at peak times.
The South Mumbai Effect
For decades, South Mumbai combined prestige and congestion — India’s most coveted addresses paired with its most crowded roads.
Line 11 aims to rebalance that reality. By introducing stations at Dockyard Road, Cotton Green, CSMT and Fort, it is expected to revitalise redevelopment and renew commercial interest in heritage districts.
Analysts project a 15–20% increase in asset values near the stations once operations stabilise, subject to project timelines and last-mile integration.
The Thane Advantage
For Thane, Lines 4 and 4A are economic catalysts. Each kilometre of viaduct adds confidence to Ghodbunder Road’s property market.
Neighbourhoods such as Manpada, Kasarvadavli and Gaimukh are already seeing rising buyer activity as stations take shape.
Luxury and villa developments now command a clear premium — “metro-ready living” — offering space and connectivity in equal measure.
The concept of metro-ready living refers to the premium lifestyle and enhanced accessibility that luxury and villa developments near metro stations offer. These properties combine spacious living with convenient metro access, making them highly desirable for residents.
Real-Estate Implications
South Mumbai
- Redevelopment momentum in heritage and dock precincts.
- Improved office occupancy and rental yields along CSMT–Fort–Colaba.
- Higher investor confidence in transit-anchored assets.
Thane & Central Suburbs
- Early connectivity premium on the Gaimukh–Cadbury Junction stretch.
- Stronger resale liquidity and end-user absorption through 2026–27.
- Ghodbunder Road reinforced as a metro-linked growth corridor.
Timelines & Reality Check
- Trial Runs: Started 22 September 2025.
- Public Opening (Phase 1): Gaimukh → Vijay Garden by December 2025.
- Extension to Cadbury Junction: By April 2026 (subject to CRS).
- Complete Line 4 (Wadala – Kasarvadavli): Target 2027.
- Line 11 (Wadala – Colaba): Under construction; expected 2029–2030.
The Bigger Picture
By 2030, Mumbai’s metro network will exceed 350 km — comparable to London’s Underground.
The Gaimukh–Colaba axis is unique because it unites the expanding residential north with the historic commercial south.
It marks Mumbai’s evolution from a radial city to a linear metropolis, with Thane as its northern gateway.
Conclusion
The metro corridor from Gaimukh to Colaba is no longer conceptual — it’s under trial in Thane and nearing staged launch.
It will reshape commuting and capital values across MMR.
For developers, investors and end-users alike, this is the infrastructure moment that will define Mumbai’s next decade of growth.
