Train Tracks
Train tracks are old and have a good purposes some of the purposes are to transport food and other things. I used to live by a big train station and I saw all kinds of trains and I always wondered how can the train tracks take all that weight on them from the trains and the cars. The I always wondered how they made trains and train tracks. So I asked my uncle how and he said metal, they bend metal and make it really strong so it can take all the weight.
