See out of 7 VB introduced so far, 1 is Flop. So, in 475 VB how many VB expected to be flop? The number will be huge, unless VB is replacing existing Rajdhani, Shatabdi, Duronto trains also included. Otherwise IR don't have 475 routes where 16 coaches full AC trains will be HIT. Noways possible many will be LOSS making ones.
