I second that, More stabling lines and Pfs even pitlines(At least one) should be considered at PDY for better operations. Even today PDY HWH and PDY CAPE are being pulled off empty from PDY to VM for Maintenance. So it's better to have pitlines at PDY which will also pave way for more new essential trains.
I also welcome the move of Upgrading Valavanur [Halt] Station into crossing station in the section of VM-PDY. This shows railway cares about trains running in the mentioned section. So, lets hope for the best.
