Cable cars are a type of transportation system that uses cables to pull vehicles along a fixed route, often up steep hills or mountains. They consist of a series of cabins or cars that are suspended from a cable, allowing them to glide smoothly over the terrain. Cable cars are commonly found in urban areas and tourist destinations, providing scenic views while efficiently moving passengers. The first cable car system was introduced in San Francisco in the late 19th century, revolutionizing public transport in hilly cities. Today, cable cars are also popular in ski resorts and mountainous regions, where they help skiers and hikers access remote areas.
