Irctc — Inconvenience to Reserved people

There is a lot of disturbance and inconvenience caused to reserved people in rayagad passenger on 17/7/2015.Unreserved people entered the train several times inspite of repeated police scoldings.They occupied every inch of the train possible blocking the door.It was not even possible to go to bathroom .A reserved old man couldnt sleep bcz of two ladies who were sitting on his berth and not giving him any place to sleep.Many people couldnt sleep peacefully.If this is the case, what is the use of the reservation system if everyone can enter the train occupy whichever seat they wish.I request the concerned authorities to take the required action immediately regarding this.
