context_page_description: High-speed rail in Australia has been under investigation since the early 1980s. Every Federal Government since this time has investigated the feasibility of constructing high speed rail, but to date nothing has ever gone beyond the detailed planning stage. The most commonly suggested route is between Australia's two largest cities, Sydney and Melbourne, which is the world's second busiest air corridor. Various corridors have been proposed for a potential high-speed line.
  The Australian rail speed record of 210 km/h was set by Queensland Rail's Electric Tilt Train during a trial run in 1998. This speed is just above the internationally accepted definition of high-speed rail of 200 km/h. The Transwa WDA/WDB/WDC class, V/Line VLocity and XPT are capable of 210 km/h. However, these trains, as well as the V/Line VLocity and Diesel Tilt Train, operate at a high of 160 km/h in passenger service.
context_section_description: In December 2000 Westrail awarded a contract to United Goninan, Broadmeadow for nine railcars to replace the 1971 built WAGR WCA/WCE class railcars. Seven were for The Prospector and two for the AvonLink service.
  The first entered service on 28 June 2004. Power is provided by Cummins engines. The new railcars are capable of 200 km/h (120 mph), but track conditions restrict their top speed to 160 km/h (99 mph).
