A tramway is a type of transportation system that uses trams, which are vehicles that run on tracks laid along city streets or dedicated routes. Tramways are often found in urban areas and are designed to provide efficient public transport for passengers. They can operate on electricity, making them a cleaner alternative to buses and cars. Tramways have a long history, with the first systems appearing in the early 19th century. Many cities around the world, such as San Francisco and Melbourne, have well-established tram networks that help reduce traffic congestion and promote sustainable urban mobility.
