Thank you for providing me insight. I get what you are saying. I did not comment about SC raj, SC raj PM is in NZM with NR based rake no question in that. You are right on that part. But with East coast express, my point is SCR gave official notification that they are doing PM at Hyd with rakes being SER. But did SER give any official notification that they are taking back the train??? If so where is the official notification give by SER is my question? Got my point? . I know how PM and rake works. You are right but this train is being exceptional temproarily. Now if thats over, SER should have sent official notification . Correct? If so, where is that?
