I doubt much about its patronage. Traveled in Shanti (INDB GNC) once. I remember getting reservation in that was much more easier than JBP SMNH, moreover that being the winter vacation season.
Further as per the TT, Shanti will just trail it all the way from INDB to ADI. Wonder what kind of TT has IR come up with. If being introduced, they could at least have a better TT.
