New Delhi, May 21 (IANS): The project to bring bullet trains to India was on the right track and the government was also trying to increase the speed of express trains, Railway Minister Suresh Prabhu said on Thursday.

"Bullet train is one big project that we are working on Feasibility studies are being done for Ahmedabad-Mumbai route with the help of Japan and Delhi-Chennai route with the help of China. The project is on the right track," Prabhu said at the 'Manthan' conclave organised by Aaj Tak here.

He, however, added that such big projects take time as a lot of investment and technical expertise is required.

Prabhu said his government was also working on a plan to improve speed of all kinds of trains, besides improving schedule of freight trains that was the backbone of Indian Railways.

"For freight, which gives two-thirds of our revenues, we are building dedicated freight corridor that will not only improve our income but also decongest our tracks, thus leading to more efficiency," he added.

The minister said apart from modernisation of India's railway network, the focus was also on providing better amenities to almost three crore passengers that use railways every day.

"We have also created a customer service portal through which passengers can get their grievances redressed while accountability of our staff will also be fixed," he added.
