May be IR thinks no need to run full fledged regular train from Bijapur to Bengaluru as no more passengers going to opt AC classes as all general class ppl travel and we don't get any income serving low category UR or sleeper passengers. IR has perception that such places like Bijapur Gulbarga Ballari dont have good high class pass to travel Bengaluru but only Hubli have and so run all trains from Hubli and Dharwad twin Cities.. This is fate of these cities. But thing is different these cities are not given chance to develop or any effort to get them develop also..
