I would like to say one thing that train from Bidar to Mangalore Central is possible. I agree Bidar is under SCR and train will mostly be going in SWR territory to reach Mangalore Central in SR. All these depends on initiation. Who is going to bell the cat. Most of the trains we got recently is because of Suresh Angadi. If he wants he can do this then Railway Board will initiate or co-ordinate with the respective zones. Route should be Bidar -- Kalburgi -- Hospet -- Hubli -- Arsikere -- Hassan -- Mangalore Central. I know SR will always say that no slots in Mangalore Central but they have slots for trains to Kerala. This is the fact. If not Mangalore Central atleast Mangalore junction should be ok.
