The South African type XF2 tender was a steam locomotive tender from the pre-Union era in the Cape of Good Hope.
Two Type XF2 tenders entered service in 1906, as tenders to the 9th Class 2-8-2 Mikado type and 10th Class 4-8-0 Mastodon type experimental steam locomotives, of which one each were acquired by the Cape Government Railways in that year. On the South African Railways roster, the two locomotives were designated Classes Experimental 5 and Experimental 6 respectively in 1912.[1][2][3]
Manufacturers
Both Type XF2 tenders were built in 1906 by Kitson and Company.[1][2][3]
The tenders, which were not identical in fuel capacity, entered service as tenders to the CGR 9th Class and CGR 10th Class of 1906, both experimental locomotives. The locomotives and tenders were designed by H.M. Beatty, the Chief Locomotive Superintendent of the Cape Government Railways (CGR), at the Salt River works in Cape Town. The tender of the 9th Class had a bunker capacity of 7 long tons 10 hundredweight (7.6 tonnes), while the tender of the 10th Class had a coal capacity of 10 long tons (10.2 tonnes).[1][2][3]
Classification
Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the South African Railways (SAR) and these two tenders were designated Type XF2.[1][3][4]

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 these two experimental locomotives were delivered new with Type XF2 tenders and were renumbered to the SAR numbers as shown.[2][3][4]
- 1906: CGR 9th Class of 1906, SAR Class Experimental 5, no. 948.
- 1906: CGR 10th Class, SAR Class Experimental 6, no. 1244.

The second letter indicates the tender's water capacity. The "_F" tenders had a capacity of 3,000 imperial gallons (13,600 litres).[3]
A number, when added after the letter code, usually indicates differences between similar tender types, such as wheelbase or coal bunker capacity.[3]
