There is a way to give AP Express its old prestige back.
1) NZM-VSKP Express should be de-linked from Dakshin Express and extra coaches should be added to Dakshin Express.
2) Change timings of Dakshin Express.
3) MOST IMPORTANT : Bellampalli, Mancherial, Ramagundam, Sirpur Kagaznagar, Chandrapur and Mathura halts for AP Express should be removed and it should be sped up.
Then...
more... according to the requirement, IR can add more and more coaches to Dakshin Exp. and NZM-VSKP Exp. which will run separately.
How is my idea?
