20. You're supposed to lay down on the track between the rails.
And the train will go right over you with no problem. That's why the wells are so deep on subway tracks. Of course, most people don't know this and even if you do, you have to keep your head straight and act. I did a lot of work on the electrical systems in subway tunnels and this is what they train you to do. My friends and I did it as kids for a kick but it's not something you'd ever do more than once because it's unbelievably filthy.
With that said, the cover of the newspaper is in really bad taste. Not ok in the least but also not surprising in the least coming from the Post.
