A cable car is a type of transportation system that uses a cable to pull vehicles along a fixed route, often up steep hills or mountains. These cars are typically suspended from overhead cables and can carry passengers or goods. They are commonly found in tourist areas, ski resorts, and cities with challenging terrain. Cable cars operate by using a motor to turn the cable, which moves the cars along the line. They are an efficient way to navigate difficult landscapes and provide scenic views during the journey. Many cities, such as San Francisco, are famous for their historic cable car systems.
