A double-decker tram or double-deck tram is a tram that has two levels or decks. Some double-decker trams have open tops. Double-deck trams were once popular in some European cities, like Berlin and London, throughout the British Empire countries in the early half of the 20th century including Auckland, Christchurch and Wellington in New Zealand; Hobart, Tasmania in Australia, and in parts of Asia. They are still in service or even newly introduced in Hong Kong, Alexandria, Oranjestad, Blackpool, Birkenhead, Franschhoek, Auckland and Douglas, mostly as heritage or tourist trams.
