Talk to a RailFan - you will learn a LOT about Trains.

Bilaspur Rajdhani desperately needs a stop at Agra Cantt because the Chhattisgarh and Kalinga Utkal routes are the worst. They are always delayed and have too many stops. It's hard to understand. Another weekly train is Jammu Tavi - Durg and Udhampur - Durg. Both of these trains have waitlists, so Rajdhani Express should definitely be allotted a stop by NR (Northern Railways). Bilaspur Rajdhani belongs to NR.
