One month back itself I heard OHE pit foundation works going on at Gadag outer on Hospet side but I don't know about OHE pit foundation works in Gadag in yard. Also in one of the videos of karthik I can see 3 small length stabling lines beside PF1 where before nothing was their. Now atleast some locos and four to three coaches can be parked their. Before that land was vacant.

Yes, even i saw those 3 stabling lines beside pf1 last month still under construction not completed..

Yes Before At that place only their were 3 MG Pit Lines where MG Coaches Maintenance was taking place and later After BG for some years those pitlines where present and after that they Backfilled all tht area to close those Pit lines and on same place their took a function for inauguration of Gadag-Bagalkot BG line but now its surprising that they want to use that land for atleast small stabling lines where Locos. some 3-4 Coaches , OHE Works Coach and other Railway Machinery can be parked.

MRJ UBL passenger trains can be extended to Gadag

Yes if they have more TAT at UBL then they can Extend them instead of keeping idle at UBL yard.But do you know any such Trains from Miraj which will be idle at UBL? Because all those trains are in RSA so they will be used for some other route services.
