Mangalore to Ballari can be Mangalore to Hyderabad.
Mangalore to Vijayapura already special is running. So a new Mangalore to Solapur via Udupi, Madgaon, Hubli, Vijayapura should be run.
Mangalore to Bidar via Hassan, Chitradurga, Ballari, Guntakal, Raichur, Kalaburagi is ok. But the problem is it needs approvals from SR, SCR, SWR as well as CR. No hopes.
Leave Solapur super fast at...
more... Bangalore itself, instead of asking for Mangalore extension. Hassan extension itself is a waste (you have Gomateshwara/ Karwar just ahead/ behind).
