A gravity railroad (American English) or Gravity railway (British English) is a railroad on a slope that allow cars carrying minerals or passengers to coast down the slope by the force of gravity alone. The cars are then hauled back up the slope using animal power or a stationary engine and a cable, chain or one or more wide, flat iron bands. The speed of the cars is controlled by braking mechanism on one or more cars on the train. The typical amusement park roller coaster is designed from gravity railroad technology.
