what is a tram

A tram is a rail vehicle that travels on tramway tracks on public urban streets. Trams are also known as streetcars or trolleys in the United States. They are a form of public transport and are operated on tramways or simply trams/streetcars. Trams can include segments on segregated right-of-way. In the United Kingdom, a tram is also known as a streetcar. Trams can be boxlike wagons running on rails, such as in a mine. Trams can also be carriers that travel on an overhead cable or rails. Trams are similar to buses, but they travel on tracks laid along roads. Trams can interact with traffic on the roads. Trams were once a common form of public transport, but many tram systems were disbanded in the mid-20th century and replaced by buses, trolleybuses, automobiles, or rapid transit. However, trams have been reintroduced in cities where they had been closed down for decades or kept in heritage use.
