Delhi Metro Opens GoA4 Line 7 And EUR312M Railcars India

DELHI, INDIA – On March 8, Indian Prime Minister Narendra Modi officially inaugurated two extensions of the Delhi Metro network, adding new sections to Line 7 (Pink Line) and Line 8 (Magenta Line). The projects include the delivery of 312 driverless train cars manufactured in India as part of Phase IV of the metro’s expansion. The event also saw the launch of planning for three new corridors under the network’s Phase-5A extension.

What Is the Full Scope of This Project?

The project encompasses new operational sections, rolling stock procurement, advanced signalling, and long-term maintenance. The inaugurated sections are Majlis Park–Maujpur Babarpur on Line 7 and Deepali Chowk–Majlis Park on Line 8, which creates new interchanges with the Yellow, Red, and Pink lines. A separate EUR312 million contract covers 312 metro cars, while a 10-year maintenance agreement for Lines 1 and 2 was also recently secured. The Line 7 extension has been equipped with the Urbalis Flo CBTC system to enable unattended train operation (GoA4), making it the first circular line in the network.

Key Project Data

How Does This Compare to Similar Projects?

Comparable public data for similar integrated metro expansion projects, including rolling stock and signalling, was not available at the time of publication. The Delhi Metro’s Phase IV, estimated at over INR 46,800 crore (approx. EUR 5.1 billion) in 2019, is one of the largest ongoing urban rail projects in the country. The scale is comparable to other major metropolitan expansions like the Mumbai Metro Line 3, which has a projected cost of over INR 33,000 crore (approx. EUR 3.6 billion).

Editor’s Analysis

The implementation of GoA4 driverless technology on the Pink Line is a strategic move that aligns with broader national trends in rail modernization. This project serves as a critical domestic proof-of-concept for high-automation systems at a time when the Indian railway signalling market is forecast for significant growth. The emphasis on 100% local manufacturing for the rolling stock further supports the government’s “Make in India” policy, positioning domestic firms to compete for future urban mobility contracts across the country.
