See the sad state of affairs of not having enough trains within KA. My friends had to travel from Badami to Bengaluru. As GolGumbaz GS are always full, they caught SUR-UBL Pass at Badami at 10:00AM to UBL, & from UBL to SBC by UBL-SBC Pass at 17:30 and reached SBC at 5:15. They cannot afford bus fare, so they travelled only by GS in trains.
So they took whooping 19hrs using chains just to travel from Badami to SBC.
Hope IR runs few daily trains from SBC/YPR to BGM/MRJ, SUR/BJP, Bidar...
more... via KLBG, Karwar via MAQ, HPT rather than just focussing on inter-state trains for migrants.
