1) BZA has good quota for AP AC express, so passengers from OGL/NGL side do not have to worry about finding seats from BZA. So, to allow passengers from any one of the three routes (BZA-VSKP, BZA-TPTY and BZA-GTL) to avoid traveling by multiple trains, the train will have to be extended in any one of these routes.
2) VSKP has a far larger population than any other city in AP. It will be several years before Amaravati develops and grows to that point.
3) 'Dedicated train connected to every part of AP'...

- If you are running train from BZA to NDLS and again running connecting trains to every part of AP, why not run the NDLS train itself to some other place in AP? For example, run it to TPTY, and passengers from other parts will board it at BZA. As long as BZA gets a good quota, it is sufficient.

2) second AP SK via Nellore is a good idea.
3) No need of originating Samata from CCT or NS. Both do not have any big end-to-end demand to Delhi. Passing trains at SLO are more than sufficient for meeting CCT-NDLS demand.
4) BZA should be the hub for intercities and long distance trains should be dumped at COA/NS/MTM or TPTY and VSKP if ECoR agrees.
