Railway Minister Sadananda Gowda is presenting his maiden Rail Budget in the Lok Sabha now. This is the first rail budget of the Narendra Modi led NDA government. The Budget is expected to adopt a realistic approach in announcing new trains and projects, expansion of rail infrastructure including modernisation of stations. It will also spell out details of future course of action for having a Diamond Quadrilateral to run high speed trains. The budget will also reflect the views of NDA government on Rail Tariff Authority and High Speed Rail Authority. With the decline in passenger earnings, it is likely to spell out its strategy for additional revenue generation.
