A gravity railroad (American English) or gravity railway (British English) is a railroad on a slope that allows cars carrying minerals or passengers to coast down the slope by the force of gravity alone. The speed of the cars is controlled by a braking mechanism on one or more cars on the train. The cars are then hauled back up the slope using animal power, a locomotive or a stationary engine and a cable, a chain or one or more wide, flat iron bands. A much later example in California used 4 ft 8+1⁄2 in (1,435 mm) standard gauge steam engines to pull gravity cars back to the summit of Mt. Tamalpais.

  • 重力式鉄道(じゅうりょくしきてつどう)は、旅客や貨物を輸送する車両が重力の力のみによって勾配を下っていく方式の鉄道である。降りた車両は獣力または定置式蒸気機関によるケーブル牽引などによって引き上げられる。坂を下る速度は車両に備えられたブレーキによって制御される。遊園地にある一般的なローラーコースターは、重力式鉄道の技術により設計されている。 (ja)

  • A gravity railroad (American English) or gravity railway (British English) is a railroad on a slope that allows cars carrying minerals or passengers to coast down the slope by the force of gravity alone. The speed of the cars is controlled by a braking mechanism on one or more cars on the train.

A much later example in California used 4 ft 8+1⁄2 in (1,435 mm) standard gauge steam engines to pull gravity cars back to the summit of Mt. Tamalpais. The typical amusement park roller coaster is designed from gravity railroad technology based on the looping track incorporated into the second railroad of the United States, the Mauch Chunk & Summit Hill Railroad, which remained in operation for decades as a tourist ride after it was withdrawn from freight service hauling coal.
