On June 11, Delhi Metro Rail Corporation (DMRC) completed work of one of the longest tunnels of the Phase 3 corridors with a tunnel boring machine (TBM) breaking through at Lajpat Nagar after boring a 1565 m long tunnel from South Extension.
The tunnel on the under construction Majlis Park – Shiv Vihar corridor is the second longest tunnel of the third phase of expansion. The longest tunnelling drive of this phase would be from Nizamuddin to Ashram on the same corridor with a length of 1691 mtrs.
The tunnel from South Extension to Lajpat Nagar is one of the twin tunnels being constructed for the up and down movement of trains. It has a diameter of 5.8 mtrs for the movement of standard gauge trains.
The Lajpat Nagar Metro station is being developed into a major interchange hub where commuters will be able to change trains between the Faridabad – Kashmere Gate corridor and the Majlis Park – Shiv Vihar corridor of Phase 3. The Majlis Park – Shiv Vihar Metro section is a 58.6 km long corridor which will cover most of the localities along the arterial Ring Road of the national capital. This entirely standard gauge section is expected to be operational by the end of 2016.
