either RAJ tag or run behind RAJ GANG at 17:50 or 18:00. that time slot is empty from both sides NDLS and CNB. once it departes CNB RT , LKO trolling becomes quite less and from there it runs on with 1-2h delay in ECR region. And ECR must give it a greater priority than a passenger, atleast treat it like an express train. Its the behaviour of ECR for every Assam bound train except DBRG/DBRT RAJ.
