Just an Answer :D

1) If present 12747/48 Palnadu SF Express runs with same schedule in future
Will Railway's add new halts Yes or No.

-...
more...

Running in same slot cannot confirm addition of halts.


2) SCR is proposing extension of heavyweights like Dakshin Express & Secunderabad–Hazrat Nizamuddin Duronto Express etc is it going to spare Palnadu SF Express type trains in future
which is already extended to remote area. - Due to reasons like congestion at Sc and as Bidr is facilitated with pitlines, SC is proposing to shift PM of these trains to BIDR and hence this extension. coming to Palnadu, it is long back extended to vkb citing such congestion reasons at Sc. further extension does not arise as there is no congestion at Vkb.


3) Is Palnadu SF Express not staying idle for more then 18 hours on Pitlines. NO.. Correct yourself.. only 11 hrs. incoming Palnadu at 2100 goes as somhadri next day mrng 8:00 hrs.


4) By providing Lhb rakes to 17201/02 Golconda Express SCR is clearly indicating
it is more interested in reducing time travel in
Golconda Express. - again speed up is not related with further extension of Palnadu.
