Vizag to BbS section needs connection to Gaya Varanasi and Prayagraj. The present Duronto slot reaches there at night 2100 and being flexi fares they're will not be such use. They have leave Vizag at night 100 to reach BBS at 730. Better to have a biweekly in OD sK slot upto Allahabad or Lucknow which have day light arrival and dep from Gaya to pilgrimage places.
