Premium trains should have a halt at larger cities stations else they run empty. Even BCT rajdhani halts at Borivali, so GGN should be given a stop. Yellow line takes 1 hr from HUDA City Centre to NDLS + 20-30 min cab ride till Huda City centre.
IGI Airport is much closer to Gurgaon than NDLS railway station and flights to Kolkata are at comparable prices. Then why would a premium traveller take the pain of going to NDLS to catch this train.
