The Cape Government Railways 2nd Class 4-4-0T of 1882 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

In 1882, the Cape Government Railways placed six tank locomotives with a 4-4-0 American type wheel arrangement in service on its suburban passenger trains out of Cape Town. Five more of these locomotives, colloquially known as Wynberg Tanks and later officially designated 2nd Class, entered service in 1888 and 1891.
