New Delhi: Amid a stiff opposition from the Delhi government over the proposed fare increase, the Delhi Metro Rail Corporation (DMRC) has said, the hike is necessary to meet input costs and to keep providing a world-class service. 
In a statement, DMRC said the input cost for the Delhi Metro has increased by over 105 per cent in energy, 139 per cent in staff cost and by 213 per cent for repair and maintenance since 2009. 

The proposal has been described as unacceptable by Chief Minister Arvind Kejriwal. In a letter to Union Minister for Housing and Urban Affairs Hardeep Singh Puri, Mr Kejriwal said, the proposed hike, to be effected from the 10th of this month, would be in violation of the recommendations of the fare fixation panel.
The Delhi Metro, which has been operational in the national capital since 2002, is at present carrying around 27 lakh passengers everyday.
