These systems use thick cables to stay up high. One or two cables stay still to act as a track. These are called track cables. A third moving cable is called a haulage rope. This rope provides propulsion, which means it gives the cabin power to move. The cabin is gripped tightly to this moving rope. This is different from a gondola lift. Gondolas use a cable that moves in a continuous loop. Trams simply shuttle back and forth between two stations.

How does the tramway actually work? Most systems are reversible. This means they move back and forth between two ends. An electric motor drives the haulage rope loop. Often, a tramway uses a two-car system called a jig-back system. One large electric motor sits at the bottom of the line. This motor pulls one cabin down the mountain. The weight of that cabin helps pull the other cabin up. The two cabins sit at opposite ends of the cable loop. They pass each other in the middle of the span.

People have been using cable lifts for a very long time. A man named Fausto Veranzio designed the first lift. However, the first working tram was built in 1644. Adam Wybe built it in Gdańsk, Poland. It did not use steel cables back then. Instead, it was moved by horses to carry soil. This helped build defenses over a river. Later, Germany built a second lift 230 years later. That one used iron wire cables instead of rope.

Tramways have many different jobs in our world. In the early 1900s, they were used for mining. They carried ore from high mountains to mills below. You can still see these in the San Juan Mountains of Colorado. Some trams are huge and carry many people. The Vanoise Express in France carries 200 people in one cabin. The Shinhotaka Ropeway in Japan carries 121 people. Some trams even have two floors. The CabriO in Switzerland has an open-air top floor for 30 people.

Today, we see tramways in cities and mountains. Many people use them for sight-seeing in the Alps. Others use them as public transport to get to work. The Roosevelt Island Tramway in New York City was a pioneer. It was the first tram in North America used by commuters. The Portland Aerial Tram opened in January 2007. In Medellin, Colombia, people use the Metrocable to travel. Even in Israel, the Rakavlit cable car helps people move.
