In 1949/50, the
Midland Railway Workshops delivered built six diesel-electric railcar sets to replace the
Governor sets. Each set had one powered ADF railcar and two ADU trailers. All were named after
wildflowers, hence the class name. The first was launched to the media on 23 August 1949 followed by a demonstration run from
Perth to
Pinjarra. They entered service shortly after, operating from Perth to
Albany, Perth to
Geraldton via
Wongan Hills and
Mullewa, Perth to
Merredin, Perth to
Chidlow, Perth to
Ongerup and
Kalgoorlie to
Esperance. All were withdrawn between 1959 and 1963 as daylight country passenger trains were withdrawn and replaced by
road coaches. ==References==
