Seattle former Melbourne tram 518
"The streetcar ceased operation on November 18, 2005, when the maintenance barn was demolished to make room for the Seattle Art Museum's Olympic Sculpture Park. A new maintenance barn was proposed to be built at Occidental Park to allow the resumption of operations. However, Metro cancelled involvement after delays made the new facility unlikely to be completed before the demolition of the Alaskan Way Viaduct began. An alternative proposal by the Port of Seattle was to extend the line northward along Myrtle Edwards Park to Smith Cove, where a new maintenance barn would be built on Port property. This proposal was not pursued. Due to a portion of the line's close proximity to the viaduct, service may need to remain suspended during construction. Service may not be able to return to the line until the completion of construction of the new Alaskan Way Tunnel, projected to be in 2018.
Currently, there is no set plan for returning the line to service at any date. As Seattle Mayor, Greg Nickels suggested that a proposed First Avenue streetcar line may be considered a replacement of the Waterfront line, and the Melbourne cars may be used for special occasions. However, current mayor Mike McGinn has expressed reluctance to build a First Avenue line and has suggested that a return of the Waterfront line may be considered."
