is it necessary that all ngp asr travellers are taking the chattisgarh . Rather one can take a superfast train to delhi and then proceed this way ngp asr can be done in 26-27 hours compared to 34 by chattisgarh. So if the AC express has a better schedule then it will get good response. Slightly unrelated note in INDB BSP sector most of the end to end traveller either travel to bpl to catch amarkantak superfast or take indb ngp express to ngp and then take gnyaneshwari or ajad hind to proceed to BSP, both these saves 4-5 hours compared to direct train which is significant imo
