Hi There 10 Z3 trams are now operating on routes from GH depot, These were cascaded from Brunswick depot last week. GH Z1 trams have been sent to Malvern to cover the withdrawal of W class trams. The only W class trams now operating on Melbourne's tram system are the 10 CCW trams based at Southbank depot. The fate of the rest of W class fleet is uncertain. Regards Anthony Tubbs
