Delhi Metro has signed a major deal with Alstom to keep its trains running smoothly. The French rail company will maintain Bombardier-built trains and equipment at Badli Depot for the next decade in a contract worth approximately €42.1 million. Indian tender documents cited a value of ₹422 crore for the CAMC, which is not a direct euro conversion.
The agreement, announced on September 12, 2025, covers much more than just routine train check-ups. Alstom will maintain Bombardier-built trains and depot machinery, carry out repairs when needed, and handle housekeeping for both the trains and the depot. It will also maintain onboard signalling equipment for all 103 trains operating on Lines 1 and 2.
What makes this deal special is that Alstom will also look after the onboard signalling equipment on all these trains. This includes diagnosing failures, providing technical support, and supplying parts for the Onboard Automatic Train Control (ATC) and Underframe ATC equipment. They’ll also install data logger cards that help spot problems before they cause delays.
“We are honoured to be entrusted by DMRC with this critical maintenance mandate,” said Olivier Loison, Managing Director of Alstom India. “With India’s urban transit networks rapidly growing and modernizing, safeguarding the reliability and longevity of essential assets such as metro trains is more important than ever.”

Delhi Metro picked Alstom after a competitive bidding process that began earlier this year. Technical bids opened on February 21, 2025, and Alstom emerged as the lowest bidder on July 9, 2025. The contract is set to begin on September 1, 2025, and run for exactly 10 years (120 months).
The company plans to use advanced predictive analytics to prevent breakdowns before they happen. This approach uses data to spot potential issues early, which should mean fewer unexpected train stoppages and delays for Delhi’s commuters.
Alstom brings significant experience to the job, currently maintaining over 35,500 vehicles across more than 250 sites worldwide. The company will provide what it calls “full-spectrum integrated maintenance” – combining preventive care, repairs when needed, and periodic overhauls.
For regular metro riders, this behind-the-scenes work matters. Well-maintained trains and signalling systems mean more reliable service and fewer delays. The housekeeping aspect of the contract also helps ensure trains remain clean and comfortable.
This isn’t Alstom’s first involvement with Indian metro systems. The company has worked on projects in several major cities including Delhi, Chennai, Mumbai, Lucknow, and Kochi. Their work aligns with the government’s ‘Make in India’ initiative to modernize public transportation.
The maintenance of Lines 1 and 2 is particularly important as these are among Delhi Metro’s busiest routes. By focusing on keeping these trains running smoothly, the contract should help maintain service on critical corridors in the capital region.For Delhi’s growing population, reliable public transit remains essential for daily commuting. This maintenance agreement represents a significant investment in keeping the metro system functioning efficiently for the millions who depend on it.
