This survey is there since many years. Let's wait and see what happens. If SWR doesn't want to depend much on YPR - DMM - GTL - WADI line, then Ginigera - Raichur, Talakal - Wadi and Ballari - Sirguppa - Sindhanur - Lingasugur lines must be constructed and commissioned ASAP. These lines will be more useful than Koppal - Sindhanur
