BSK enjoys the unmatchable priority in UP direction when it departs from CNB on time, it gets a clear line till NDLS then as usually trains from ALD are usually delayed by atleast 30-45 mins. So there is no one to troll or even overtake BSK. When BSK gets delayed then there is AD, PR and SG the NCR favourites and they can overtake and even troll any train. These train run are not ruined at any cost.
