Delhi Metro impossible Every 90 Seconds Trains

 Living in Delhi had become like living in a gas chamber, the High Court had commented in early December, forcing the government to introduce urgent measures to clean its air rated the world's most polluted by the World Health Organisation. Responding to appeals on reducing pollution in the national capital and improving public transit facilities, Delhi Metro said it currently runs trains at a minimum interval of 2:15 minutes. Representing the transit authority, Solicitor General Ranjit Kumar told the Chief Justice TS Thakur and Justice R Banumathi that Delhi Metro was increasing the number of coaches in its trains from the existing six to eight coaches. Mr Kumar said Under the third phase of the metro's expansion that would become operational in stages starting December 2016, another 486 coaches would be added, Delhi Metro had run an additional 70 trips during the trial, over its usual 3,200 trips, to meet the surge in people using public transport.
