Tatanagar - Brahmapur VB was introduced keeping in mind the passengers of Chaibasa - Dangoaposi - Kendujhargarh - Jakhapura Section. First Railways decided to introduce a VB in this section. Then it began planning on the Source and Destination. So first Tatanagar - Puri was planned. When Puri expressed inability to handle one more VB, Tatanagar - Brahmapur was selected. If some problem would arise in Brahmapur destination, some other destination would be selected, but in every case this VB would run through this section and not through any other route. On the other hand, If any VB runs in the route you have recommended, it will not halt at Jhargram. It's halts would be Tatanagar, Hijli, Baleshwar, Bhadrak, Jajpur Keonjhar Road, Cuttack, Bhubaneswar, Khurda Road Junction, Puri.
