The Cape Government Railways 2nd Class 2-6-2TT of 1875 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

The first mixed traffic locomotives to enter service on the new 3 feet 6 inches Cape gauge mainlines of the Cape Government Railways were 2-6-2 Prairie type side-tank engines which were delivered between 1875 and 1879. Four-wheeled tenders were also acquired and the locomotives could be operated in either a tank or tank-and-tender engine configuration, as circumstances demanded. These locomotives were later designated the Cape 2nd Class.
