I saw lot of rails fixed to PSC sleepers kept in Gadag jn yard and also some on train standing on goods loading yard I guess those are for Gadag hotgi doubling as now we already have lines laid for Hospet Hubli doubling except GDG jn outer and also I saw works going on between Gadag Holealur by this i am getting strong feeling that SWR next doubling target will be some where between Gadag to Holealur or Bagalkot to badami/Lakhmapur.Its good move as they don't want to waste time until construction of Krishna and Holealur bridge they may be planning to commission sections without bridges..
