Kosi is a dream train of former RM Lalu prasad Yadav,,and ECR let it be with them,no need to destroy super,better they run both separately,Hatia Saharsha super express. And Purnia to Dehrionson Kosi Express. ECR will never run this SER train on time,unka apna v on time nhi chalta. Il never like super to be so pathetic as danapurs train are.
