Extension to KRNT will be good. Considering it's timings in the KCG-VSKP run, it will not be the first choice for most people. So, CC can be changed later based on the traffic pattern.
17015/16 has been known to people as Visakha for a long time now, and regular passengers will continue to use the name even if it is removed. In the VSKP-BZA section at least, people will continue to refer to this train as 'Link' only. I think the names can remain as they are now.
To be fair though,...
more... it was not 'taken' by SER. Both BZA-VSG and BZA-UBL were known as 'Amaravathi express' and when the VSG train was extended to HWH, they just didn't rename it. At that time, both trains were not daily, so there was no need to change the name.
