yes Near to Bannikoppa and yeah minor civil works Started as KA govt Handed some 50km line to Railways but as you said IR not funding yet.But from British periods this line was planned but Due hyderbad Nizam Not cooperate so the IR utilised funds of this line to SC-mahbubnagar-dhone line that time. but British period plan was to connect SC to Goa via Wadi,Ilkal ( ilkal have granites Resoource which is why it is Prefered in original plan) but now in the name of Hyderabad ktk progress they changed via Kushtagi yelburga to cover more hyderabad Karnataka region in this line. gadag is just for name but line starts from some other place in hyderabad karnataka region.I think ppl of gajendragad Ilkal needed this very much and it will be more feasible too compared to present new route of IR.
