The Transwa WDA/WDB/WDC class are a class of railcars built by United Goninan, Broadmeadow for Transwa in 2004-2005 to replace the WAGR WCA/WCE class railcars on the AvonLink and Prospector services in Australia. They are capable of high-speed operation.


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.[1][2][3]

The first entered service on 28 June 2004.[2][4] 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).[5]

These consist of three WDA driving cars, three WDB driving cars without buffet, and one motored WDC non-driving car. These form two 2-car and one 3-car sets. The AvonLink sets consists of one WDA and WDB. The AvonLink lacks the buffet and entertainment system the Prospector has, but the AvonLink has a whistle and a horn, while the Prospector only has a horn.[2]
