Well, for starters, because it’s dangerous and you could die like a couple in South Africa did back in 2008. Also, because you might cause train delays as was the case for a couple in Sweden who were caught doing it in a car parked way too close to the tracks.
“Often when cars are sitting near the tracks, it can be copper thieves at work or unfortunately a person who has tired of life,” the train dispatcher Mattias Hellberg explained. “It was two people who were very happy and having a little moment of passion. The driver told them they weren’t being very discrete there and asked them to get moving.”
This seems like common sense to me, but I suppose a reminder is in order. Having sex on or near the train tracks is a really stupid idea. [The Local]
