wahi toh bata rahe hai, this route needs Vande Bharat, actually more than many bad routes where the VBs are running. IR/ER is just missing a trick by restricting it only to Gaya, otherwise, 8C for Gaya would have been good enough. If run till BSB, those seats which go vacant post after passengers on HWH DGR, HWH ASN, and HWH DHN alight, new passengers will take up the seats between DGR BSB, ASN BSB, and DHN BSB, taking the occupancy levels beyond 100%.
