Cape Government Railways Karoo Class locomotives

The Cape Government Railways Karoo Class locomotives include three locomotive models, all designated Karoo Class, and one more which entered service shortly after the South African Railways renumbering and classification program came into effect in 1912.

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 Karoo Class locomotives were grouped into four different sub-classes on the new South African Railways.
