Minister of Railways Ashwini Vaishnaw on Friday informed the Rajya Sabha that there is no proposal to privatise Indian Railways. In a written reply to a question in the Rajya Sabha, Mr Vaishnaw said, to bridge the gap in capital funding, Public-Private Partnership mode is envisaged to facilitate faster development of network, manufacturing of rolling stocks and delivery of passenger and freight services. He said, it is estimated that Railway infrastructure would need an investment of 50 lakh crore rupees between 2018 to 2030. He informed that there is also a proposal to use PPP mode for inducting modern rakes to run passenger trains on select routes with an objective to provide improved service delivery to passengers. The Minister said, however, the responsibility of train operations and safety certification rests with Indian Railways in all such cases. Mr Vaishnaw also said that Ministry of Railways has invited bids for induction of about 150 pairs of passenger train services to be operated over select routes through PPP.
