Funicular
A funicular (), also known as an inclined plane or cliff railway, is a cable railway in which a cable attached to a pair of tram-like vehicles on rails moves them up and down a steep slope, the ascending and descending vehicles counterbalancing each other. Funiculars of one sort or another have existed for hundreds of years and continue to be used for moving both passengers and goods. Its name derives from the latin, ''funiculus'', diminutive of ''funis'', meaning "rope".
==Operation==
The basic idea of funicular operation is that two cars are always attached to each other by a cable, which runs through a pulley at the top of the slope. Counterbalancing of the two cars, with one going up and one going down, minimizes the energy needed to lift the car going up. Winching is normally done by an electric drive that turns the pulley. Sheave wheels guide the cable to and from the drive mechanism and the slope cars.
