In a significant financial achievement, Ministry of Railways has shown an improvement in its operating ratio (OR) for the year 2014-15. Provisional accounts indicate an OR of 91.3 per cent, an improvement over the target of 92.5 per cent and better than a revised estimate target of 91.8 per cent. OR indicates how much money is spent on day-to-day operations to earn a rupee. OR at 91 per cent means the Railways saves Rs 9 from its operations while spending Rs 100. Railways said this is also an improvement over the 2013-14 OR, which had closed at 93.6 per cent.
