Is it normal to be aroused from subway train curve screeching

Is it normal to be sexually attracted to subway train noise on sharp curves. I realize I've had this addiction for over three years, and the history dates back to when I was seven. But I get really hard when I listen or ride the subway and it goes on a curve. The squeal or screech is like so pure, it turns me on very much, along with the vibration roughness. Then I learned the noise is from steel on steel, which in return turned me on even more, the principle of metal rubbing on metal sounds sexual itself. Im also talking NYC subway trains
