One can definitely expect a train either an ON Express or a Passenger from Visakhapatnam to Bhadrachalam once the proposed line between Kovvur - Bhadrachalam is completed.I think for the time being they should introduce an Express from Visakhapatnam to Bhadrachalam via BZA - DKJ since it's quite a long route an O.N Express would be a good addition with a name like "Bhadradri".
