New Delhi - Darbhanga Bihar Sampark Kranti just has 1 AC 3-tier coach, that means only 64 people can travel in 3 AC in Bihar Sampark Karnti Express. In those 64, 20 are reserved for tatkal, 4 for senior citizens, a few for passengers for intermediate stations and a few in HO quota. Only 10 berths are available in general quota for this train in 3AC and waiting list goes upto 400. Shame on IR and ECR.
