History edit

In May 1950, D1 became the first diesel to operate on an Australian main line. The eight D class locomotives hauled trains on Australian Iron & Steel's, Port Kembla until a downturn in the early 1980s saw most of the class withdrawn.[1][2][3] D6 and D7 were reactivated with the former remaining in service until 2004.[4]

Three have been preserved:[5]
