A San Francisco cable car on the Powell & Hyde line A cable car （usually known as a cable tram outside North America） is a type of cable railway used for mass transit in which 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.

The powerhouse has two horizontal single-cylinder engines.
The lithograph shows a hypothetical prototype of a cable powerhouse, rather than any actual built structure.
Poole & Hunt, machinists and engineers, was a major cable industry designer and contractor and manufacturer of gearing, sheaves, shafting and wire rope drums.
They did work for cable railways in Baltimore, Chicago, Hoboken, Kansas City, New York, and Philadelphia.
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 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, as its first-ever elevated railway which ran from 1 July 1868 to 1870.
The cable technology used in this elevated railway involved collar-equipped cables and claw-equipped cars...
