Union Housing and Urban Affairs Minister Manohar Lal has announced that Delhi Metro will soon set a new global record by becoming the longest metro network in a single city. Currently, New York holds the top spot with a 399 km metro line, while Delhi Metro is operating on a 394 km network. With the upcoming 12 km Aerocity to Tughlakabad Golden Line expected to open by December 2025, Delhi will secure the title with a total network length of 401 km.
Milestone Achieved in Phase 4 Expansion
In a major step forward, Delhi Metro Rail Corporation (DMRC) successfully completed an underground tunnel between Kishangarh and Vasant Kunj Station as part of the Tughlakabad-Aerocity corridor. The tunnel breakthrough was celebrated at Vasant Kunj metro station, where Minister Manohar Lal confirmed the project is progressing as planned.
The newly completed tunnel is 1550 metres long and was constructed using a 91-metre-long Tunnel Boring Machine (TBM). Another parallel tunnel on the same corridor is scheduled to be completed by June 2025.
India on Track for the Second-Largest Metro Network
Minister Manohar Lal highlighted that metro projects are operational or underway in 29 states across India, with the total network now at around 1000 km. This makes India the third-largest metro network in the world, and soon it will take the second spot, just behind China.
Advanced Technology and Safety in Tunnelling
The Vasant Kunj tunnel was constructed at an average depth of 23 metres using Earth Pressure Balancing Method (EPBM) technology. Precast concrete tunnel rings were used to line the tunnel, ensuring strength and durability. Continuous monitoring of ground movements ensured safety, and no settlements were reported during construction.
Delhi Metro continues to set new standards in urban infrastructure, combining cutting-edge technology with world-class safety and efficiency.
