there is already a slot avaialble if it has to be converted to a rajadhani ...MAS-NZM Duranto/Raj slots are vacant for 1 day atleast in both up and down ....all south rajadhanis and durantos are given the same slot...so no need to even give a new slot if a weekly rajadhani needs to be introduced... but whats the point ? are people ready to lose a daily train for a single day Rajadhani that too with dynamic fare ??? i dont think thats a good idea...
if they want, they will anyhow will start one later on and slot will be for sure the same south raj/duranto slot only .. :)
