Friction Wheels on a lift-hill

Friction Wheels are tires that are connected to the track of a roller coaster to control the speed of the train. Friction Wheels are often used in stations and brake runs (usually block-sectioned). On some roller coasters, this same method is used on launches, or on lift-hill. This machanism is so flexible that unlike lift chain it can work for spiral lift hills.
