In India though we have one of the biggest Railways networks in the World, still today people travel on the roofs of electric trains when there is severe rush! Though the authorities they see this thing happening they are unable to stop this practice as the rush is so much that it become s impossible for the limited number of police men to stop this practice1 there have been many accidents because of this! This is a pathetic state of affair! How can such things be prevented? Your comment please! Thanks !
