Electric trams (known as streetcars or trolleys in North America) are first experimentally installed in Saint Petersburg, Russia, invented and tested by Fyodor Pirotsky as early as 1880.

These trams, like virtually all other electric trams to be developed, use either a trolley pole or a pantograph, to feed power from electric wires strung above the tram route.
