Indian Railways — sleeper class berths

Address:

Hyderabad, Andhra Pradesh, 500081

Regardingthid indian railways sleeper class berths. As the fans that was kept in the compartments can't able to provide a 1% air for the passengers who alloted upper, side upper births.
Kindly change the directions of the fans so that public will not face soffocation & lack of air in the train & due this lack of air we think the general compartment is better than this sleeper class.
