Mumbai’s public transport is getting a futuristic upgrade as French manufacturer Alstom revealed the first driverless train for Mumbai Metro Green Line, with the six-car trainset expected to arrive in the city within the first or second week of December.
This is the first of 39 trainsets built to connect Wadala-Thane on Metro Line 4 and Metro Line 4A.
As part of a fleet of 39 six-car Metropolis trainsets, the train was unveiled at Alstom’s manufacturing facility in Sri City, Andhra Pradesh, on Wednesday, October 14. The first train is expected to be shipped by the end of November 2026, with a journey of around seven to ten days to Mumbai.
With a green-blue design, it will feature airflow-based cooling, wheelchair accessibility, and dedicated bicycle racks.
The trains are designed for a maximum safe speed of 90 km/h and an operational speed of 80 km/h. Additionally, the fleet will use communication-based train control technology to enable fully automated, driverless operations once the required systems and infrastructure are ready.
Which areas will the Mumbai Metro Green Line connect?
Mumbai Metro Green Line 4 is an elevated corridor including 30 stations, running from Kasarvadavali in Thane to Bhakti Park in Wadala. Its extension – Mumbai Metro Line 4A – adds two stations connecting Kasarvadavali to Gaikmukh, adding another 2.7km. The Mumbai Metropolitan Region Development Authority (MMRDA) estimates the corridor to reduce travel time by 50% to 75%, depending on road conditions.
The residential and commercial neighbourhoods linked to the Mumbai Metro Green Line include Ghatkopar, Bhandup, Vikhroli, Mulund and Thane. Plus, it will provide interchanges with Eastern Express Highway, Monorail, Central Railways and other Mumbai Metro corridors: Metro Line 2B, Metro Line 5 and Metro Line 6.
While the arrival of the first trainset is a key milestone, it does not mean the Mumbai Metro Green Line is ready for passenger service. The dedicated depot for trains, signalling and other systems needs to be readied, while construction and commissioning work on the corridor continues. As per reports, the full corridor of Metro Green Line is targeting operations by 2027.
As of now, December 2026 is the month when the first driverless train is expected to roll into Mumbai – not necessarily when Mumbaikars can take their first ride.
