DELHI (Metro Rail News): Larsen & Toubro (L&T) has initiated the first tunnelling work for Delhi Metro’s Silver Line with the commissioning of the TBM DZ1122 at Chhatarpur Station. The TBM launch shaft will be headed towards Kishangarh Station, with a 1.27 km long tunnel planned for the line’s Package DC-09, which connects Kishangarh – Saket G Block.Â
The Silver Line is part of the Phase 4 project and will connect Aerocity-Tughalakabad through 16 stations in four civil packages. The 6.51 km section by L&T, valued at Rs. 1428 crore, will be constructed with twin-tunnels in the middle of the Silver Line, connecting Kishangarh Station with a cut and cover ramp to the west of Saket G Block Station. The section includes four stations at Chhattarpur (interchange with Yellow Line), Chhattarpur Mandir, IGNOU, and Neb Sarai. The CRCHI earth pressure balance (EPB) machine’s cutter head and shields were lowered using a strand jack “mega lift” system, saving time.
