That kid had better grow-up to be someone very important indeed!
By the way......it seems to me that someone screwed-up when they built that deck. Logic tells me that when you build such a thing, it should be at least LEVEL and not sloping towards the tracks.
At our subway stations here in Pittsburgh, there is a gentle upwardly sloping strip right near the end nearest the tracks. It prevents things rolling slowly enough to be stopped from going over the edge. It's not foolproof, but it is a helpful measure.
