South African type XS tender


The South African type XS tender was a steam locomotive tender from the pre-Union era in Transvaal.
Type XS tenders entered service in 1911, as tenders to the 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.

Manufacturer

Type XS tenders were built in 1911 by the American Locomotive Company.
In 1911, the Central South African Railways placed nine Mallet articulated compound steam locomotives in service, built by ALCO. These locomotives were designated Class MF on the South African Railways in 1912. The Type XS entered service as tenders to these engines.

Characteristics

The tender had a coal capacity of, a water capacity of and an average maximum axle load of.

Locomotive

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 often also the 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.
Only the first batch of nine Class MF locomotives of 1911 were delivered new with Type XS tenders. In 1912, they were renumbered in the SAR number range from 1619 to 1627.

Classification letters

Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR. The first letter of the tender type indicates the classes of engines to which it could be coupled. The "X_" tenders could be used with the following locomotive classes:
The second letter indicates the tender's water capacity. The "_S" tenders had a capacity of.
