The Cape Government Railways 6th Class locomotives include twelve locomotive models, all designated 6th Class irrespective of differences in wheel arrangement or characteristics.
When the Union of South Africa was established on 31 May 1910, the three Colonial government railways (Cape Government Railways, Natal Government Railways and Central South African Railways) were united under a single administration to control and administer the railways, ports and harbours of the Union. The Cape Government Railways 6th Class locomotives were grouped into twelve different sub-classes on the new South African Railways.
