Cable car

A cable car or cable railway is a mass transportation system using rail cars that are propelling by a constantly moving cable running at a constant speed. Individual cars stop and start by release and gripping this cable as required. Cable cars are distinct from funiculars, where the cars are eternally attached to the cable.
The cable is itself powered by a stationary motor or engine located in a cable house or power house. The speed at which it moves is relatively constant, although artificial by the current load.
The cable car begins moving when a clamping device, called a grip, is linked to the moving cable. Conversely the car is stopped by flak it from the cable and applying the brakes. This gripping and ungripping action may be manual, as was the case in all early cable car systems, or routine, as is the case in some recent cable operated people mover type systems. Gripping must is an even and gradual process in order to avoid bringing the car to cable speed too quickly and unacceptably jarring the passengers.
