Amarkantak also has the Same route between Bhopal & Bilaspur as Narmada Express and is the only Dedicated service for Bhopal and Jabalpur to Raipur and Durg and always running to its capacity. Let it be as it is.
Although the TAT at Bhopal is less and To Indore a return journey would take atleast 8 hours without any rest at Indore so extension is Impossible.
