History
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hauled trains on Australian Iron & Steel's, Port Kembla until a downturn in the early 1980s saw most of the class withdrawn.[1][2][3] D6 and D7 were reactivated with the former remaining in service until 2004.[4]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]
- D1 by the NSW Rail Museum, Thirlmere.
- D6 by the Lithgow State Mine Heritage Park & Railway, Lithgow. This unit is still stored in Port Kembla.
- D7 by the former ARHS ACT Division, Canberra.
