Politically KL might get MAQ CBE or TVC CAN thats it. When technical and other calculations are done we can see many options also. Main advantage of VB is to do with loco reversal since both sides cabins present LR time would have been reduced. OR LR will be just crew change at reversal place but I never seen such kind of utilisation in IR which is very unfortunate. They are complementing VB as another premium service to shatabhi caterance as of now. I think that is poor utilization of VB technology. They should try routes where Shatabhi/Tejas cannot be done even though patronage is high. They can also try some innovative routes which never got premium caterance.
