may be a Vande Sadharan like Janshatabdi would do more justice here. VB is a very costly affair.. people have to shed out a lot of money to travel in these trains..
DDN VB is a super hit as it connects two capital cities.. LJN-Ayodhya-GKP VB was bound to get flop ..
major trip pair destinations in India have already got good connectivity.. Affordability may prove to be a major consideration factor , railway should consider it while launching VB between two tier 2/3 cities..
