Tourist trolley

The vehicles are usually fueled by diesel, or sometimes compressed natural gas.

The name refers to the American English usage of the word trolley to mean an electric streetcar.

As these vehicles are not actually trolleys, and to avoid confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses".

Municipal operators may mix tourist trolleys in with the regular service bus fleet to add more visitor interest or attract attention to new routes.

In San Francisco, tourist trolleys mimic the city's famous cable cars.
