Indian Railways — vivek express

I have boarded in vivek express 15905 from vijayawada bza to srikakulam che in sleeper class s2. Here situation is very pathetic. Almost 100s of ppl are sitting and standing. They are not having tickets also. They look very rude. We are not able to sir or board to our seat. Looping very dirty. Y they are boeing allowed in a sleeper class where people boooked for sleeping. This is like à general bogie only
