En:Heritage streetcar

Heritage streetcars (also known as heritage trams or nostalgic trams) are a part of the efforts to preserve rail transit heritage. In addition to preserving street-running rail vehicles, heritage streetcar operations can include upkeep of historic rail infrastructure. Working heritage streetcars are closely related to the growing global heritage railway movement and form a part of the living history of rail transport.
The vehicles are called streetcars or trolleys in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with trolley being preferred in the eastern US and streetcar in Canada and the western US. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses".
Museums, heritage tram line operators, and amateur enthusiasts can preserve original vintage vehicles or create replicas of historic vehicles to re-create or preserve streetcar technology of the past. Heritage vehicles that are kept fully functional can be used on heritage tramlines or for charter traffic.
