take it directly from kiul to deoghar via jasidih go via dhn mdp.
why are you going extra route via bhagalpur . also bhagalpur deogarh line is extremely slow.
why also will you waste diesel.
the idea should be to provide fastest intercity then you should take shortest route.
or...
more... you should go via dhn since it would be the fastest option in real life .
ecr train will never run via bgp in real life.
