The atlas shows a connection between Visakhapatnam station and Visakhapatnam port.
As far as I remember, VSKP station never had a connection to the port. The line going to the port branches off at Gopalapatnam and trains go through the Waltair marshalling yard till the Reception and Dispatch yard of the port (parallel to VSKP station), where the port trust's locomotives takeover.

From VSKP the line continues till the old Vizagapatnam town station (VZT) and terminates there.
Unless a some connection has been made in recent years, this section of the map has to be changed.
RBS too doesn't show a direct path between VSKP and the port. The shortest path reported by RBS for goods traffic goes from VSKP to VZP through SCMN (reversal at SCMN to go through the marshalling yard lines).
