This train follows the same route as that of Bangalore-ERS intercity express but surprisingly does not change to electric engine. For the entire 800 km it is hauled by diesel. The railways could save a huge amount of fuel cost if an electric engine is used from Salem onwards just as it is done for the intercity express.
Sometimes dont understand the rationale of railways.....They try to increase fares in various ways,superfast charge,reservation charge, cancellation charge etc etc but dont try to look at ways where they can save huge costs from their end.
