Exactly, instead of introducing VB on these routes, Rajya Rani goes way ahead. Be its CC, or stoppages, they serve the cities en route better. VBs as a train should be introduced between pair of cities having some criteria, like per capita income, frequency of travellers /patronage, MPS of route, demand and should be restricted 500-600 kms with atleast average speed of 80 km/h, otherwise intercity/RR/Jan shatabdi serve the cities better.
