Humsafar is a concept to be introduced in high density tested corridor which have premium travellers. For a sector like HWH Vskp/BZA super fast train with biweekly with both AC and non AC will work better. It will also go like AP AC super fast exp which doesn't have enough of traffic in non seasons. Particularly the premium part of 50% berths which attract flexi fares will not have takers as it's timings don't suit to VSKP needs to HWH and from HWH.
