Why Rajdhani? This is my only question. First of all, Rajdhanis are supposed to originate from state capitals, and Hubballi/Vijayapura clearly aren't state capitals. A Duronto would make much more sense. But if a Duronto's flexi fare is too high for people in these areas, then a new SF should be introduced like AP.
My only request is to not damage the KSKs further. Please. The route has been screwed with, way too many times. None of them are preferred from Bengaluru to Delhi anymore.
