DELHI (Metro Rail News): The second tunnel boring machine (TBM) for the under-construction Silver Line in Delhi Metro’s Phase-IV project has commenced its work at Airforce Station, Tughlakabad. The tunnel boring machine, named ‘Amrit,’ will undertake the excavation of a 2.67 km long tunnel from Airforce Station, Tughlakabad to Maa Anandmayee Marg station. This remarkable tunneling effort will be the longest drive during Phase 4 of the project.
Previously, on March 3, the first TBM initiated its drive, excavating a 1.27 km long tunnel connecting Chhatarpur and Kishangarh stations. The expansion work under Phase-4 involves the construction of 65.20 km of new lines across 3 different corridors in Delhi, featuring 45 metro stations.
The three corridors in Phase-4 include the extension of the Magenta Line, which connects Janakpuri West to RK Ashram Marg (28.92 km), the extension of the Pink Line connecting Majlis Park to Maujpur (12.55 km), and the upcoming Silver Line linking Tughalakabad to Aerocity (23.62 km). The Silver Line will link the operational Violet and Airport Lines.
There will be fifteen stations along the Aerocity–Tughlakabad corridor—four elevated and eleven subterranean. It will also include four interchange stations at Aerocity, Saket, Chattarpur and Tughlakabad.
The Silver Line’s alignment will make it simple for commuters from a variety of locations, including as terminal 3 at Indira Gandhi International Airport, south Delhi, Vasant Kunj, IGNOU, and Mahipalpur.
