what is tram

A tram is a rail vehicle that travels on tramway tracks on public urban streets, sharing road space with other traffic and pedestrians. Trams are designed to run on fixed rails and are powered by electricity from wires above them. They are usually used as a form of public transport and are commonly found in cities. Trams can include segments on segregated right-of-way, and most tram systems also include at least some off-street running. The tracks that a tram runs on are called a tramway, and the system itself can be called a tramway system. Trams can be called streetcars or trolleys in North America. Some trams run mostly on reserved tracks, with only short stretches of on-street running. Trams can be used for carrying passengers or loads in a mine.
