WAGR ADE/ADT class

The WAGR ADE class, also known as the Governor class, was a class of six diesel railcars operated by the Western Australian Government Railways between 1937 and 1962. The first was delivered in December 1937 from Newcastle upon Tyne by WG Armstrong, the Armstrong Whitworth company, and it was the first diesel-electric rail vehicle to enter service in Australia. The other five followed in 1938 in knocked down form and were assembled at the Midland Railway Workshops, and each was named after a Governor of Western Australia. Because the railcars proved too small for their traffic, five AG Gilbert carriages were adapted as trailers until six ADT trailers were delivered by the Midland Railway Workshops in late 1939. The class served on services such as Perth to Merredin, Perth to Katanning and Geraldton to Mullewa, was displaced by the Wildflower class railcars in 1949 and 1950, and the last was withdrawn in April 1962. ADT 9 and ADT 12 survive.
