The parliamentary standing committee on railways has asked the national transporter to diversify beyond staple bulk commodities like coal, iron ore, and cement to better its freight performance, and recommended a service model similar to the passenger system. While the standing committee’s report is not available yet, a statement by the committee said that freight remains the backbone of Indian Railways, contributing nearly 65 per cent of its revenue and coal, iron ore and cement constitute more than 60 per cent of freight loading and revenue generation through freight operation.
