About
Mumbai Metro Line 7 (Red Line) is a 16.5 km fully elevated metro corridor running north-south along the Western Express Highway median in Mumbai's western suburbs. It connects Andheri East to Dahisar East, with phased revenue services from January 2022 (Aarey-Dahisar segment) and full line opening in 2023 (Andheri-Aarey segment).
Line 7 is operated by MMRDA itself (not under a PPP concession like Line 1) — making it the first MMRDA-direct-operated metro line. Construction was executed in 2 packages by L&T and Reliance Infrastructure between 2016 and 2022 at ₹6,208 crore. The corridor uses Bharat Earth Movers Limited (BEML)-built 6-coach trainsets — the first major BEML metro contract — running on 25 kV AC overhead.
The line shares its viaduct route along Western Express Highway with Line 2A (Dahisar West-DN Nagar, parallel/elevated). Together, Lines 7 and 2A provide a complete west-side metro orbital around Mumbai's western suburbs — connecting to Line 1 at Andheri.
Daily ridership averages 230,000 as of 2024 — among India's busiest single-line metros given the corridor's chronic traffic congestion. The line cuts Andheri-Dahisar travel from 75 minutes (road via Western Express Highway) to 25 minutes.
