The Violet Line was originally planned to open in March 2010.^[6] On 12 July 2009, a portion of an under-construction bridge collapsed when its cantilever pier collapsed on load of launching girder at Zamrudpur, near East of Kailash, on theCentral Secretariat –Badarpur corridor. Six people were killed and 15 others injured.^[7] The day after, on 13 July 2009, a crane that was removing the debris collapsed, and with a bowling pin effect knocking down two other nearby cranes, injuring six.^[8]

An extension from theBadarpur metro station of the line was opened on 6 September 2015 to provide connectivity to the neighbouring satellite city of Faridabad. This is the second line to cross the Delhi-Haryana border after theYellow Line to Gurgaon. This extension runs fully elevated for 13.87 km (8.62 mi) and has 9 stations.^[9]
