Once Harihar to Hospet line is opened, Gol Gumbaz express can be diverted via the new line. It will provide another daily link between Mysore and Hospet. Also link Hospet to Badami, Bagalkot and Bijapur do not have connection. Also distance is same, and one loco reversal avoided if it goes via Davangere Hospet. Bangalore to Hubli pax will not be much affected as the quota is RLWL.
