they can make average speed at least to 85 so that it can complete the journey with in 8.15 Hours. But they can not skip Vijayawada on the grounds of revenue since end to end will not be filled to 100% in VB. intermittent stations only help in filling the seats in VB i think so. Now a days 20833 from Vizag not filling more seats but 20834 is getting good response i think so.
