Honestly not sure about NGP-JBP VB, as I see there is 1 dedicated train between JBP and NGP, also served by REWA-ITWARI too, but patronage in AC coaches for those trains are not that great, many passengers got there tickets upgraded from SL to AC coaches regularly so I cannot comment on whether a VB is required between JBP and NGP maybe someone from JBP might be able to tell better.
please wait...Translate to EnglishI don't really know much about NGP-JBP VB, but I do know that there is one train that goes between JBP and NGP. It's also served by the REWA-ITWARI train. However, not many people travel in the AC coaches of these trains. A lot of passengers regularly upgrade their tickets from SL to AC coaches. So, I can't really say if a VB is needed between JBP and NGP. Maybe someone from JBP would know better.
