yes , but in the morning there are several flights from BPL to DEL. VB is competing with different modes , which are not limited to trains. i just dropped a thumb rule here. the end to end passenger that too in CC composition will prefer this train more over others , if travel time reduces to less than or around 7 hours. Instead of reducing the slack time they are increasing it. This train is capable of covering this distance within 7.15 hours. i think in the future they will surely reduce the travel time...
