One more suggestion: Let SWR take back udyan along with CSMT GDG express. Have RSA.
Currently Gadag express has RSA with Mandovi. Udyan with Siddeshwar. If my suggestion is accepted, Udyan and CSMT GDG can have RSA. Mandovi and Siddeshwar can have RSA.
Gadag express can get extended upto Bangalore via Hospet Davanagere, thereby providing day time connectivity between Solapur Bijapur Bagalkot Gadag to Hospet Davanagere Arsikere Bangalore.
