Indian Railways — unauthorized people in sleeper class

This is not a new issue and this is happening for the past seven to eight months. People without tickets and with general tickets are boarding the train at katpadi as well as arakonam junction and trying to occupy our berths. Also many of those are sitting on the pathway and blocking our way to toilets. This is not being taken care by the tt or by the rpf. Around 200 people of this kind are boarding the train on daily basis and no one was caught by either tt or rpf. Could you please take necessary steps to avoid as this is seriously affecting our travel.
