Pune Metro Line 3 Enters Service with Alstom and Siemens Technology

Pune Metro Line 3 has entered passenger service in India, with Alstom Metropolis trains operating on the 23.3 km elevated route connecting the city’s Hinjewadi IT hub with Shivajinagar.

The line, inaugurated virtually by Indian Prime Minister Narendra Modi on 4 November 2026, serves 23 stations and is designed to improve public transport connections along one of Pune’s main employment corridors.

The project is being delivered through a public-private partnership involving Tata Group company TRIL Urban Transport and Siemens. Alstom is supplying the metro trains, while Siemens is providing the signalling, electrification and other rail systems required to operate the line.

22 Metropolis Trainsets

Alstom is supplying 22 three-car Metropolis trainsets for Pune Metro Line 3. Manufactured at the company’s facility in Sri City, Andhra Pradesh, the trains form part of India’s Make in India initiative.

Of the 22 trainsets, 20 have been delivered to the Maan depot and commissioned for passenger service. They have completed mandatory testing and received approvals from India’s Research Designs and Standards Organisation (RDSO) and the Commissioner of Metro Railway Safety (CMRS).

The trains have a maximum operating speed of 85 km/h and can carry up to 1,000 passengers each. Passenger features include dedicated spaces for people with reduced mobility and safety systems, while the trains are powered by Alstom’s energy-efficient Mitrac propulsion system.

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. Designed to operate efficiently for decades, our trains support sustainable urban travel and a better quality of life, helping build a more connected Pune, with less time in traffic and more possibilities for everyone.

Signalling and Electrification

Siemens is delivering an integrated rail systems package for the project, including its Trainguard MT communications-based train control (CBTC) signalling system and electrification infrastructure. Its scope also covers telecommunications, including the data backbone, train radio, telephones, CCTV and access control, as well as a digital station manager, depot workshop equipment and overall system integration.

The line uses a 750V DC third-rail electrification system. Siemens is also providing a 10-year full-service maintenance contract covering the signalling and electrification systems.

Designed for Grade of Automation 2 (GoA2) operation, the line supports semi-automated train operations. The system is also designed to allow a future upgrade to GoA4, enabling fully automated operation.

According to Siemens, the combination of its signalling technology and integrated systems will support reliable operations and help reduce journey times between Hinjawadi and Shivajinagar by up to 50%.

Léon Soulier, Executive Vice President Turnkey Business at Siemens Mobility, said:

The inauguration of Pune Metro Line 3 marks a proud milestone for this prestigious turnkey project, and Siemens is honored to have partnered with the Tata Group to bring it to life. The new metro line will significantly enhance the quality of life for Pune's citizens and transform their everyday journeys.

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. This delivers faster, safer, and more reliable connectivity across one of Pune’s busiest corridors, reflecting India’s strong commitment to sustainable and efficient public transportation solutions for its growing population.
