THE prime minister of India, Narendra Modi, presided over the official opening of two extensions to the metro network operated by Delhi Metro Rail Corporation (DMRC) on March 8.
Line 7/Pink has been extended by 12.3km from Majlis Park to Maujpur Babarpur. The extension of Line 8/Magenta runs for 9.5km from Majlis Park to Deepali Chowk, providing interchange with Line 2/Yellow at Badli and with Line 1/Red at Madhuban Chowk.
The extensions are the first new infrastructure to be completed under Phase IV of the Delhi Mass Rapid Transit System (MRTS) project. “Delhi Metro’s network has gone beyond 375km,” Modi said.
Alstom has supplied Urbalis Flo CBTC signalling for the Line 7 extension, designed for future operation at Grade of Automation 4 (GoA4). According to the manufacturer, Line 7 will be the longest metro line in India with unattended driverless operation at GoA4.
Under a €312m contract awarded in November 2022, Alstom is supplying a total of 312 metro cars for Phase IV, entirely manufactured at the plant at Sri City in the state of Andhra Pradesh, which Alstom says is its largest urban rolling stock manufacturing site in Asia. Featuring high recyclability and low energy consumption, the trains are designed to operate at up to 85km/h.
Maintenance contract
In September 2025 DMRC awarded Alstom a 10-year contract to maintain 103 trains supplied by its predecessor Bombardier that operate on lines 1 and 2 of the Delhi network. Including onboard signalling equipment, the contract is worth €42.1m.
Alstom previously supplied signalling and train control systems for lines 1, 2, 5, 6 and 7.
