The W-class trams are a family of electric trams built by the Melbourne & Metropolitan Tramways Board (MMTB) between 1923 and 1956. A small fleet continue to operate on the tramway network of Melbourne, Australia, where they are used on the City Circle tourist route and the Colonial Tramcar Restaurant service. The W-class tram is a cultural icon to Melbourne, those that remain in Melbourne are classified by the National Trust of Australia. W-class trams were introduced to Melbourne in 1923 as a new standard design. They had a dual bogie layout and were characterised by a substantial timber frame supplanted by a steel under frame, a simple rugged design, and fine craftsmanship (particularly the older models). The W-class was the mainstay of Melbourne's tramways system for 60 years. A total of 752 trams of all variants were built.
