The F class was based upon the
South Australian Railways 800 class. The seven members of the class entered service with the
Midland Railway of Western Australia in 1958, and, together with the rest of the company's assets and operations, were taken over by the
Western Australian Government Railways in 1964. The first (F42) was withdrawn in November 1984.
Hotham Valley Railway have preserved F40 and F44 while
Rail Heritage WA have F43. F41 is also on display at Moora. ==References==
