One more thing so many passengers are there who travel in AC classes don't know that AC class also has a dustbin they just throw their waste either below their seat or they just go & open the gate & throw the waste outside train whether it is a platform or any outer, one more thing i noticed evrytime i travelled in AC class that the dustbin always gets fully filled & no one cleans it or throw the waste of dustbin when a train stops at big station, this shud be done dustbin shud be cleaned when a train stops at big station
