Pune Metro Line 3 opens with 20 Alstom trainsets in service

Pune Metro Line 3 entered passenger service with 20 of Alstom’s 22 three-car Metropolis trainsets, linking Hinjewadi and Shivajinagar over 23.3 km of elevated track; Indian Prime Minister Narendra Modi inaugurated the line virtually on 4 November 2026.

The line serves 23 stations and targets better public-transport connections along one of Pune’s main employment corridors, with Hinjewadi–Shivajinagar travel time presented as the principal service benefit.

Who is building and operating Line 3?

Delivery sits under a public-private partnership involving Tata Group company TRIL Urban Transport and Siemens. Alstom supplies the rolling stock, while Siemens provides the signalling, electrification and wider rail systems needed to run the line. The announcement does not identify a separate train-operating entity or publish fares, ridership forecasts or a project cost.

What fleet is carrying passengers?

Alstom’s order covers 22 three-car Metropolis trainsets, of which 20 have been delivered to the Maan depot and commissioned for passenger service. The announcement gives no delivery date for the two remaining trainsets.

• Manufacturing: Alstom manufactures the sets at its Sri City facility in Andhra Pradesh under the Make in India initiative.
• Commissioning: The 20 delivered sets have completed mandatory testing and received approvals from India’s Research Designs and Standards Organisation (RDSO) and the Commissioner of Metro Railway Safety (CMRS).
• Operating limits: Each trainset has a maximum operating speed of 85 km/h and a stated capacity of up to 1,000 passengers.
• Passenger provision: Dedicated accommodation for people with reduced mobility and on-board safety systems form part of the specification.
• Propulsion: Alstom’s Mitrac system powers the trainsets and is described by the manufacturer as energy-efficient.

Olivier Loison, managing director of Alstom India, said: “At Alstom, we are proud to support this transformation with our 100% made-in-India Metropolis trains, engineered for Pune’s evolving mobility needs.” He also said the trains are designed to operate efficiently for decades, support sustainable urban travel and give commuters less time in traffic.

How will signalling and maintenance work?

Siemens’ package covers the control and physical rail infrastructure, plus the communications and maintenance equipment that ties the route’s operations together.

• Control: Trainguard MT communications-based train control (CBTC) provides the signalling platform for train movements.
• Power: A 750V DC third-rail electrification system supplies the line’s traction power.
• Communications: The telecoms scope includes the data backbone, train radio, telephones, CCTV and access control.
• Operations: Siemens also supplies a digital station manager, depot workshop equipment and overall system integration.

Designed for Grade of Automation 2 (GoA2), the signalling supports semi-automated train operations. The system also allows a future upgrade to GoA4 for fully automated operation, but no upgrade date, cost or funding decision appears in the announcement.

Under a separate 10-year full-service maintenance contract, Siemens will maintain the signalling and electrification systems. That gives the line a defined maintenance term, although the announcement gives no contract value.

Will journey times fall by 50%?

Siemens says its signalling and integrated systems will support reliable operation and reduce journey times between Hinjewadi and Shivajinagar by as much as 50%. The figure is a supplier projection, not a measured result: the announcement gives no baseline, timetable or actual running-time comparison.

The 85 km/h maximum operating speed cannot substitute for corridor-wide performance data because end-to-end time also depends on the operating plan. Likewise, the energy-efficient Mitrac claim has no published consumption figure against which to assess operating cost.

Léon Soulier, executive vice president Turnkey Business at Siemens Mobility, said: “By combining our strong integration and project management capabilities with our advanced core technologies—such as our state-of-the-art CBTC system—we are enabling a reduction in travel time by nearly 50% for commuters.”

He described the intended result as faster, safer and more reliable connectivity across one of Pune’s busiest corridors. Siemens also presents the project as a way to improve daily travel and support sustainable, efficient public transport.

Operationally, the opening leaves three checks: whether the last two trainsets arrive; whether GoA2 delivers the reliability needed for the service plan; and whether measured end-to-end journeys approach the 50% estimate. The source provides no frequency, loading or cost baseline to turn those claims into a service forecast.

The next milestones are delivery of the two outstanding trainsets, publication of operating results, and a dated plan for GoA4, none of which the announcement schedules.
