The Rack and Pinion gear is used to convert between rotary and linear motion. Often the pinion rotates in a fixed position and the rack is free to move - this arrangement is used in the steering mechanism of most cars.
Alternatively, the rack may be fixed and the pinion rotates moving up and down the rack. This latter arrangement is used as the drive mechanism for Funicular Railways (steep railways up the side of hills).
