The Cape Government Railways NG 0-6-0T of 1903 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope. In 1902, Arthur Koppel, acting as agent, imported a single 0-6-0 narrow gauge tank steam locomotive for a customer in Durban. It was then purchased by the Cape Government Railways and used as construction locomotive on the Avontuur branch from 1903. In 1912, this locomotive was assimilated into the South African Railways and, in 1917, it was sent to German South West Africa during the First World War campaign in that territory.
