Unreserved people getting into sleeper coaches (except in the de-reserved sleeper ones) are a nuisance, TTE and railways MUST DO SOMETHING about this, be it following an airport like system where only people with valid tickets are allowed into the area of the platform where sleeper coaches come or strict checking inside the coaches and heavy fines for people that break the law. The state of trains coming from the North and entering the south, especially trains like 12511, 12508, 18189 etc. is so bad in the sleeper coaches, the ticketless ones are harassing families/women who travel with valid tickets, steal their stuff etc., they sleep on the floor and in the bathrooms. I remember a time 15 years back when sleeper coaches in these trains were so travelable and occupied by middle class people but now it is full of ticketless migrants. So much money poured on to Vandhe Bharat...
more... and all those luxury trains made for the rich while absolutely nothing is done in regards to this.
