The W-class trams are a family of electric trams built by the Melbourne & Metropolitan Tramways Board (MMTB) between 1923 and 1956. Over the 33 years of production, 752 vehicles spanning 12 sub-classes were constructed, the majority at the MMTB's Preston Workshops.
A small fleet continue to operate on the tramway network of Melbourne, Australia, where they are used on the City Circle tourist route. The W-class tram is a cultural icon to Melbourne: those that remain in the city are classified by the National Trust of Australia.
As well as Melbourne, W-class trams operate on tourist and heritage systems across the world. A number of older variants have been withdrawn from service and later sent to cities such as Copenhagen, San Francisco, Savannah and Seattle, and by private enthusiasts. In 2018, 134 W-class trams were offered to the Australian public for new uses.[1]
As of December 2021, only 11 W class trams remain in service in Melbourne, all of which are W8 trams operating on the City Circle tram route.[2]
