A funicular is a type of railway system that uses a cable-driven mechanism to transport passengers up and down steep slopes. It consists of two cars that are connected by a cable, with one car going up while the other descends. This design allows for efficient movement on hilly terrain, making funiculars popular in mountainous regions and cities with steep hills. Funiculars operate on a track that is often inclined at a significant angle. They are commonly found in tourist areas, providing scenic views, and in urban settings, where they help commuters navigate challenging landscapes. Examples of famous funiculars include the Peak Tram in Hong Kong and the Duquesne Incline in Pittsburgh.
