Delhi Metro To Break Records With Golden Line Expansion, Becoming World's Largest By 2025

The Delhi Metro, which began operations on December 24, 2004, is expected to set new records by the end of 2025. As the second oldest metro system in India, it serves Delhi and the neighboring regions with an impressive network stretching 395 kilometers. The metro is managed by the Delhi Metro Rail Corporation (DMRC). Currently, it transports an average of 1.5 million passengers daily. Excitingly, the introduction of the Golden Line - a new segment of underground and elevated routes will enable the metro to surpass New York’s 399-kilometer metro network. Once functional, it will become the longest metro system in a single city worldwide.

Housing and Urban Affairs Minister Manohar Lal recently announced the inauguration of this significant extension. And according to the DMRC, a tunnel boring machine (TBM) has completed excavation work at Vasant Kunj station. At Vasant Kunj station a 91-meter-long TBM has created a tunnel stretching 1,550 meters. A second tunnel on this same stretch is expected to be completed by June 2025.

The DMRC is dedicated to enhancing connectivity in South Delhi and key areas, with a considerable 40.109 km of underground tracks planned under Phase 4. Notably, the Tughlakabad-Aerocity corridor encompasses 19.343 km of underground routes.

As of March 2025, the Delhi Metro operates ten color-coded lines across 289 stations within its 395-km network. Its reach extends beyond Delhi. And connects cities like Ghaziabad, Faridabad, Gurugram, Noida, Bahadurgarh, and Ballabhgarh, thereby serving the broader National Capital Region (NCR).

The continued expansion of the Delhi Metro promises to enhance accessibility and significantly reduce travel times for commuters.
