The South African type XD tender was a steam locomotive tender from the pre-Union era in the Cape of Good Hope. The Type XD tender first entered service in 1901, as tenders to the British-built of the three versions of 6th Class 4-6-0 Tenwheeler type steam locomotive which were acquired by the Cape Government Railways in that year. These locomotives were designated Class 6H on the South African Railways in 1912.
