I assume you are aware that from Shivaji bridge to New Delhi , Trains have to move in serial order one after another. Thats why If BSP rajdhani reaches Shivaji Bridge and HWH rajdhani (somehow 1hr delayed) also reaches Shivaji Bridge at same time , Then also BSP will not be given home signal to move ahead. HWH will be given more priority and this thing has been personally seen by me while onboard BBS rajdhani.
So you can imagine If BBS Rajdhani is getting better priority than BSP rajdhani while entering NDLS, then HWH is whole different level.
Here...
more... these members are shouting for Speeding up of thes Rajdhani which is NOT AT ALL possible as Same slot sharing is done between NGP-NZM by MAS GR/RAJ , SC RAJ and BSP RAJ. So best thing that NR can do is Terminating BSP RAJ at NZM itself.
