Is train banenka 4 points hai.
1 to Perumbur for chennai for MTM as there is no train till now. so PER can be point for Chennai.
2 Current MTM-YPR Kondaveedu is a Tri-Weekly and in other Route which Doesnt touch any part of this Route. so one more train needed for MTM for YPR/SBC/KJM.
3. BZA Doesnt have a dedicated train to MS...
more... or SBC except a passenger for SBC this can fill the Gap.
4 MTM/BZA doesnt have a dedicated train to JTJ side except in RLWL/PQWL Quota. so a train is needed.
Think you understand this trains importance now.
