Yes bro ,we all can suggest and discuss here ,but ultimate responsibly is with SR and RB .I have strong feeling SR deliberately is avoiding speedup of TN .
Very sad to see ordinary express train Patalkot and other sfast like Sachkhand ,Sridham ,Gondwana have aggresive schedule in Bpl - Delhi -BPL section but TN ,GT ,KK and Dakshin left out . .
Next yr self and Vijaywada were discussing Lhb for Ratnachal ,but SCR has put it cold storage and has different items on agenda
