[Classic SF Shot]: The Cable car
A cable car or cable railway is a mass transit system using rail cars that 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. Traditional cable car systems
The best known existing cable car system is the San Francisco cable car system in the city of San Francisco, California. San Francisco's cable cars constitute the oldest and largest such system in permanent operation, and it is the only one to still operate in the traditional manner with manually operated cars running in street traffic.
