A funicular is a type of railway that uses a cable system to transport passengers up and down steep hills. It consists of two cars that are connected by a cable, allowing one car to go up while the other comes down. This design helps balance the weight, making it energy-efficient and safe. Funiculars are often found in hilly cities or tourist areas, providing a unique way to enjoy scenic views. These railways are popular in places like San Francisco and Switzerland, where steep terrain makes traditional trains impractical. Riding a funicular can be a fun experience, offering a smooth ride and a chance to see beautiful landscapes from a different perspective.
