TN bound trains have long stationary timings at YPR-SBC. SCR shouldn't be a zone serving long bound trains.
Apart from Seshadri there should be 2 more daily trains starting within AP.
(Kondaveedu,Vskp another daily to SMVT)
YPR...
more... can shift long bound trains like Sanghamitra,GKP,Kaziranga to SMVT and allocate space for trains with distance less than 1000kms travel.
