GNT Guntakal needs 30 mins more and also Guntakal Hubli 30 mins more. Not possible to cover 400km in 6.5 hrs even after doubling and need sectional slack. Same 260km need 4.5 hrs otherwise the train will run late every day upto Madgoan.
The frequency of the train should be increased to daily if not 3 days to Belgavi/Kolhapur.
