i have travelled through it too..
it was a very slow intercity on a third world route which has been upgraded now..
VB has a different class of travelers all together which would have preferred either Rajdhani or flight or cars to travel ADI rather catching a slow intercity on a non priority route..
we have seen better occupancy in...
more... the CC and EC classes of VB as compared to CC class of an intercity on the same route..
a VB between these city will drift passengers from other comparable modes...
