The South African type XS tender was a steam locomotive tender from the pre-Union era in the Transvaal.
Type XS tenders entered service in 1911, as tenders to the 2-6-6-2 Superheated Mallet type steam locomotives which were acquired by the Central South African Railways in that year. These locomotives were designated Class MF on the South African Railways in 1912.[1][2][3]
Manufacturer
Type XS tenders were built in 1911 by the American Locomotive Company (ALCO).[1][2][3]
In 1911, the Central South African Railways (CSAR) placed nine 2-6-6-2 Mallet articulated compound steam locomotives in service, built by ALCO. These locomotives were designated Class MF on the South African Railways (SAR) in 1912. The Type XS entered service as tenders to these engines.[1][2][3]
Classification
Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR and these tenders were designated Type XS.[1][3]
In the SAR years, tenders were numbered for the engines they were delivered with. In most cases, an oval number plate, bearing the engine number and tender type, would be attached to the rear end of the tender. During the classification and renumbering of locomotives onto the SAR roster in 1912, no separate classification and renumbering list was published for tenders, which should have been renumbered according to the locomotive renumbering list.[3][4]
Only the first batch of nine Class MF locomotives of 1911 were delivered new with Type XS tenders, renumbered in the SAR number range from 1619 to 1627.[2][3][4]

The second letter indicates the tender's water capacity. The "_S" tenders had a capacity of Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)..[3]
A number, when added after the letter code, usually indicates differences between similar tender types, such as wheelbase or coal bunker capacity.[3]
