Technical Design of the Incline

The Inclined Plane was designed by Samuel Diescher of Pittsburgh, internationally known as an engineer of vertical railroads, having designed the Monongehela, Duquesne, Fort Pitt, and Castle Shannon inclines. 



He also designed machinery to operate the first Ferris wheel, unveiled at the Chicago World's Colombian Exposition in 1893.  His design for the Cambria Inclined Plane utilized many of the engineering schemes he had tested in previous inclines.

The design is simple: a balanced inclined plane with a double track, each with an eight-foot gauge. The two cars permanently attached to steel cables, counterbalancing each while in operation.  As one car rises, the other is lowered. Power is only needed to lift the net weight.

The angle of the railway is set at 35 degrees, 25 minutes; the length is 896.5 feet.  Its perpendicular lift is 502.2 feet, to an elevation of 1,693.5 feet.
