SCR should do the linking of pf 6-9 asap, IMO.
Trains like
Indore Lingampalli
Hubbali SC

should be extended to CHZ via Suchitra
While trains like Hussain Sagar, Hyderabad Express, Duronto & Hadapsar can easily be shifted to Charlapalli via SC.
In exchange Pune Duronto can shift to Nampally, allowing SC platforms to catch a breather.
