Yes it's still running with D Loco till Itarsi from Danapur (last time saw it some 2 months ago). I don't know if the link has changed till Jabalpur or not.
I've dropped many of my friends going to Satna, Jabalpur, Varanasi, Patna etc. in Gyan Ganga Express and Pune Danapur Express, I'm not that fond of their maintainence or timings plus they're always full.
So my first choice is Allahabad Duronto, second choice is Patna Humsafar and Last Choice is Flight to Nagpur and then Bus to Rewa. Now since...
more... Habibganj Humsafar has started I want to try it till Habibganj and then either a Bus or Rewanchal Express till Rewa.
