You can travel in Kudachi Bagalkot line to Hyderabad, when your grand children become senior citizens. Till then, line will not be available.
My point was that even now a shorter route is available, which can link Hyderabad, Kalaburagi, Solapur, Pandharpur, Miraj, Belagavi. Why not run a train? Why torture people taking them in all zigzag routes?
