CDG got 3 Shatabdi not 2!! VB so far is less stoppage train as compared to Shatabdi but will replace Shatabdi Rake in future the way Tejas Rake is doing for Rajdhani!!
Shatabdi with less TAT need quick turnaround which will be easy by VB single unit rake, to show Pit Lines at SM Stations without need of tedious & repetitive LR!!
It will be no surprise to find Single Unit Non AC VB Rake to replace JS/ICE in future!!
