Chakradharpur is in Jharkhand, but it never fell in the route of any Rajdhani, so because of SBP, JSG and ROU it got this only Raj, might have taken RNC route but since RNC had a dedicated Raj and via CKP distance is same and the tracks are faster, they have chosen. Also I feel PRR stop was required in place of ANR, it is just because of Railway's own requirements. But CKP and PRR areas have good Odiya population.
