The Kalkaji Mandir metro station is an interchange station between the Violet Line and the Magenta Line of Delhi Metro.[2] It serves the area of Kalkaji in South-East Delhi, and provides access to many tourist sites such as Kalkaji Mandir, Lotus Temple, Prachin Bhairav Mandir and ISKCON Temple.[3] The station was opened along with the first section of the Violet Line from Central Secretariat - Sarita Vihar on 3 October 2010, in time for the Commonwealth Games opening ceremony on the same day.[4] Its interchange with the Magenta Line was opened on 25 December 2017.[5]
The Violet Line station is elevated while the Magenta Line station is underground. Both of these are connected by a 260 m (850 ft) long pedestrian bridge.[6] The underground station is situated at a depth of 17 m (56 ft) and both of its tracks pass through a single-tube twin tunnel, which was constructed using the New Austrian tunneling method (NATM). This had to be done because the station had to pass beneath the operational Violet Line.[7]
