Viral video: A joyride on train's roof, and a smooth way down

Travelling on the roof of a train should be a strict no-no. One may fall off, get hit by trees and structures of bridges or may even get electrocuted. A video that has gone viral on social media shows some people travelling on the roof of a train. One doesn't know how they climbed up the roof, but they can be seen getting down the roof by sliding on a pole where the train has stopped. Men, women and even children can be seen sliding down the pole with ease, showing this was a regular feature of their train travel.
