Statistics says India is going to be the country with the highest population in the world in few years, more than China, the actual one. So imagine how the railways in India look alike in rush hour, it’s something very horrific.
Especially in the suburban trains. There is no seats for everyone, so traveling hanging off the outside doors or anything you can hold is a fact. It can be such a crush that you can simultaneously bury your face in someone’s armpit or down there.
