A tram network is a system of vehicles that run on tracks, typically found in urban areas. Trams, also known as streetcars or trolleys, provide public transportation and connect various parts of a city. They usually operate on dedicated lanes or tracks, making them an efficient way to move large numbers of passengers. Tram networks can reduce traffic congestion and lower pollution levels by encouraging the use of public transport. Many cities, such as Melbourne and San Francisco, have well-established tram systems that enhance mobility and accessibility for residents and visitors alike.
