Yes very congested at Vskp between 8-11 apart from express trains there memu passengers Rayagada , kakinada , palasa . Every 10-15 mins there is a arrival. So between Gopalpatanam and vskp they allow 3 trains at a time in block section and take them into PF in 5-7min gap of each train and at the time they need to depart trains outgoing 1-5 pf are blocked by incoming so need to manage PF occupancy too. Though NTES shows RT there is 5-10mins difference.
