Random Rails

Why do we keep train tracks that are never used? They just sit there and you have to drive over them and it's been years since they've been used. I mean, think about it, if we got rid of all of those useless tracks we could reuse the metal, plant some trees there and restore the land so that there's not a huge, barren streak. We might even be able to squeeze a few more houses in to the jampacked neighborhoods. There must be some ulterior motive. Maybe we keep them there in case another huge war comes to the United States and they're thinking it would be easier to just repair them than to completely replace them. Who knows. All I know is that they are annoying to drive over when you know that no train will be coming any time soon. It just takes all the fun out of racing to the tracks and hoping you'll beat the train. I mean they could at least remove the parts that go over roads, but that's just me.
