The Delhi Metro told the Supreme Court on Thursday that it was not possible to increase the frequency of train services as it would involve a huge expenditure.
Solicitor General Ranjit Kumar told the apex court bench of Chief Justice T.S. Thakur and Justice R. Banumathi that having trains every 90 seconds instead of the existing 2.15 minutes would require massive investment in infrastructure, reports The Economic Times.
The court was hearing a batch of petitions seeking its intervention to address the alarming increase in air pollution in the national capital.
However, Solicitor General Ranjit Kumat told the court that Delhi Metro was increasing the number of coaches in its trains from the existing six to eight coaches.
