Cable car (railway)

A cable car is a type of cable transportation used for mass transit where rail cars are hauled by a continuously moving cable running at a constant speed. Individual cars stop and start by releasing and gripping this cable as required. Cable cars are distinct from funiculars, where the cars are permanently attached to the cable, and cable railways, which are similar to funiculars, but where the rail vehicles are attached and detached manually.

The first cable-operated railway, employing a moving rope that could be picked up or released by a grip on the cars was the Fawdon railway (or wagonway) in 1826, a Colliery railway line. The London and Blackwall Railway, which opened for passengers in east London, England, in 1840 used such a system. The rope available at the time proved too susceptible to wear and the system was abandoned in favour of steam locomotives after eight years. In America, the first cable car installation in operation probably was the West Side and Yonkers Patent Railway in New York City, which ran from 1 July 1868 to 1870. The cable technology used in this elevated railway involved collar-equipped cables and claw-equipped cars, and proved cumbersome. The line was closed and rebuilt, and reopened with steam locomotives.

In 1869 P. G. T. Beauregard demonstrated Cable car at New Orleans and issued U.S. Patent 97,343.

Other cable cars to use grips were those of the Clay Street Hill Railroad, which later became part of the San Francisco cable car system. The building of this line was promoted by Andrew Smith Hallidie with design work by William Eppelsheimer, and it was first tested in 1873. The success of these grips ensured that this line became the model for other cable car transit systems, and this model is often known as the Hallidie Cable Car.
