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.

Famous quotes containing the words gravity and/or railroad:
“Here I sit down to form characters. One I intend to be all goodness; All goodness he is. Another I intend to be all gravity; All gravity he is. Another Lady Gish; All Lady Gish she is. I am all the while absorbed in the character. It is not fair to say—I, identically I, am anywhere, while I keep within the character.”
—Samuel Richardson (1689–1761)
“This I saw when waking late,
Going by at a railroad rate,
Looking through wreaths of engine smoke
Far into the lives of other folk.”
—Robert Frost (1874–1963)
