How to people made the railway station litter.

Answer 1

There are eatable stall in railway station.. We all enjoy the eatables and throw up the remaining there in station itself. Thus it get littered as many follow this way.

Answer 2

When Trains arrive late.People usually pass their time by playing,eating,drinking so they usually throw the garbage of rappers etc on floor instead of throwing in dustbin. This way people litter the railway station.
Hope it helps :)
