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 (currently operational between Badarpur and ITO) and the Majlis Park – Shiv Vihar corridor of Phase 3.
The Majlis Park – Shiv Vihar Metro section is a 58km long corridor, which will cover the arterial Ring Road of the national capital.
