There are some passengers from Dungargarh or Ratangarh who travel to Kolkata once in a while, though. But I guess the reward is not worth extending such a premium train to BKN. Rajasthan is a price sensitive market, especially Shekhawati region and an intercity type train would be a major hit instead of Duronto. Even VB or better, a Vande Metro could be better than a dynamically priced train!
