Indeed SECR gives priority to Delhi bound trains through this route via katni but this train is alive bcz of its petronage from BSP-R-DURG-NGP-BPL so cant change its route but need enough speedup and maybe elimination of stops like Rajnandgaon and Gondia or maybe one of these at MPS upgrade to 130kmph and better priority in SECR's territory and also slight speedup in NGP-BPL section..
