A tram is a type of public transportation that runs on tracks, usually found in cities. It is similar to a train but typically operates on shorter routes and is designed to carry passengers within urban areas. Trams can be powered by electricity, often supplied through overhead wires, making them an eco-friendly option for commuting. Trams are often seen in cities like San Francisco and Melbourne, where they provide a convenient way for people to travel. They stop frequently, allowing passengers to hop on and off easily. This makes trams a popular choice for both locals and tourists exploring the city.
