A time-bound plan was underway to eliminate all unmanned railway crossings across the country, he said winding up a discussion in the Lok Sabha on the Demand for Grants for 2012-13 for his ministry.
Roy said his endeavour would be to generate more revenue for Railways through advertising, use of vacant land and commercial utilisation of railway stations.
The Lok Sabha then passed the Demands for Grants for Railways by voice vote.
Rejecting a demand by members, Roy said he was not in favour of setting up Rail Tariff Regulatory Authority, a proposal mooted by his predecessor Dinesh Trivedi.
Admitting the problem of overcrowding in suburban trains, Roy said steps are being taken to strengthen suburban train service in Mumbai, Howrah, Sealdah and Chennai by providing more trains.
Highlighting the importance of linking remote and tribal areas with rail network, he said though some routes are not financially viable, the Ministry is committed to provide rail link for the economic development of those areas.
Seeking more funds, Roy requested Prime Minister Manmohan Singh and Finance Minister Pranab Mukherjee to provide additional allocation to meet the rising demands of the Railways to achieve efficiency and provide more safety.
