Edward's Friction Wheels Here we have some fun little decoration to make your Rollercoasters look a little more profesional. Friction Wheels! They don't do anything but sit there and look pretty. Also once installed they will appear in the Scenary section. Not walls, nor fences, nor billboards, but under the Pawn&Dice icon. Btw, these are directional. When placed, watch the wheel animation and you'll see if you've put it backwards or not.
