Also one thing I observed in your video that new line which u covered will run until passing ROB up to km 55 and after that they stop it. So I think that is new Bypass line which going to join Bijapur line with new small station on Gadag Bijapur line. And present line on which train was running will join to Present single line of Bijapur and one more double line on another side which u not covered will join to present single line of Gadag Hubli.. Like this 4 outer lines get ready and also one bypass line.. They left still much gap between ROB considering future plans of new lines pass below ROB..
