Mumbai, April 2026: The metro rail network in Mumbai has crossed the significant milestone of 100 kilometres, emerging as the second-largest metro system in India after Delhi NCR. With this expansion, Bengaluru has slipped to third place in terms of operational metro network length.
The achievement comes following the inauguration of new stretches on Metro Line 9 and Metro Line 2B, pushing the total operational length of the Mumbai Metro network to approximately 101 kilometres.
New Corridors Strengthen Connectivity
The newly operational Phase 1 of Metro Line 9 connects Dahisar East to Kashigaon, marking the first metro link between Mumbai and the neighbouring Thane district. Meanwhile, Phase 1 of Metro Line 2B, connecting Mandale to Diamond Garden in Chembur, enhances connectivity in the city’s eastern suburbs.
These additions are expected to significantly reduce travel time for daily commuters and improve last-mile connectivity across key residential and commercial hubs.
Network Expansion and Integration
With the latest additions, Mumbai now operates six metro lines. Key corridors such as Metro Lines 7 and 9 are now integrated, allowing smoother transit across the western suburbs. Interchange facilities at strategic stations are expected to further ease passenger movement.
Impact on Urban Mobility
Officials state that the expanded metro network will help cut travel time on several routes from over an hour to around 30 minutes. The project is also aimed at reducing road congestion and dependence on suburban rail and road transport systems.
National Ranking
Delhi NCR Metro: ~416 km (largest in India)
Mumbai Metro: 100+ km (2nd largest)
Bengaluru Metro: ~96 km (3rd largest)
Future Plans
Authorities have outlined ambitious expansion plans, with the full completion of Metro Line 9 expected by the end of 2026 and Line 2B by 2027. Once completed, the Mumbai Metropolitan Region’s metro network is projected to reach over 300 kilometres.
