The D1 class were a class of diesel locomotives built by Commonwealth Engineering, Granville with English Electric traction equipment for Australian Iron & Steel's, Port Kembla steelworks in 1950–1951.

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hauled trains on Australian Iron & Steel's, Port Kembla until a downturn in the early 1980s saw most of the class withdrawn. D6 and D7 were reactivated with the former remaining in service until 2004.

Three have been preserved:

• 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.
