LAHORE In the wake of recent surge in petroleum product prices, Pakistan Railways management has decided to raise the fare at specific trains, a Railways official told TheNation on Thursday. The govt on Wednesday has decided to increase POL products prices upto Rs 5.13 per litre with effect from December 1st and the decision would directly affect Railways exchequer for about Rs 20 million per month. 'We prepared the summary for increasing 15 to 20 per cent fare on specific trains as the Railways cannot bear such burden itself, said the official. However, it was told that implementation of process would least take one week. Fare would be increase only at long routes. 'Railways had increased the fares on February 2011 but after that the diesel prices were increased at least three times. It was said that the utility was already facing severe financial crunch with the closure of total freight operation and only passenger trains were operating on countrywide routes. The rail eight months before had raised the fare in a view to generate funds to meet its operational expenses. Then it was also hoped that raise would generate an additional revenue of Rs 2.30 billion annually. The raise is likely to be announced to avoid further crisis in the Railways.
