This train caters for AP people. We can't expect this train extended to Gangavathi / Koppal. This train goes to Vijayawada. Koppal, Gangavathi, Ballari, Hosapete, Raichur, Yadgir people will require more trains towards Kalaburagi and Hyderabad rather than Vijayawada. Also Hubballi - Gadag - Koppal - Hosapete - Ballari section has 2 daily trains (17225/17226 & 56501/56502) and one train which runs in 4 days of a week (18047/18048) to Vijayawada.
