The South Australian Railways D class was a class of 4-4-0 steam locomotives operated by the South Australian Railways.
In August 1859, Robert Stephenson and Company delivered two 4-4-0 locomotives to the South Australian Railways for use on the Gawler to Kapunda line. A further six were delivered between 1862 and 1867. The first was withdrawn in February 1896 with a further three withdrawn by 1904. The remaining four were used on construction trains on the Pinnaroo line. They were then used as shunters with the last withdrawn in November 1932.[1]
