basava started as something and ended as something, but it has different caterences true. it cant be however used comfortably for sbc bjp or bgk, for which golu would still be a better option. the unexplored shortest route would be sbc gtl gdg bgk bjp which has not much trains even though it would connect major ka cities. but it doesn't seem to be a problem considering other factors.
if you look at occupancies of maq mas trains also, end to end crowd is very less and is understandable as well.
