Former Delhi Metro Chief Dr E Sreedharan on Thursday said he was not in favour of bullet train at present, instead emphasised on the need for the Indian Railways to improve the existing facilities. “This is not the right time for bullet train in the country, but there was a need for improving existing facilities, speed, infrastructure and comforts of passengers,” Sreedharan, also known as the ‘Metro Man’ for developing the Delhi Metro, said. He said the Railways should concentrate on betterment of the existing facilities at the outset and think of bullet train later. “May be after 8-10 years, we may require bullet train,” Sreedharan said. To a query on the proposed bullet train between Mumbai and Ahmedabad, Sreedharan, who had spent about 36 years with the Railways, expressed his satisfaction over the progress of the Nagpur Metro Rail project. The Nagpur metro project, he said, was using a new technology where the via duct will be of 8.5 metres against the 10 metres in other Metro Rails across the country.
