The South African type XE tender was a steam locomotive tender.

Type XE tenders were rebuilt from Type XC1 tenders, which had entered service in 1897 and 1898. The rebuilding resulted in a tender with a larger water tank and larger coal bunker.[1][2]

Origin

The original Cape Government Railways (CGR) 6th Class locomotive and tender was designed at the Salt River works of the CGR in Cape Town in 1892, under the supervision of Western System Locomotive Superintendent H.M. Beatty. In 1897 and 1898, the CGR placed a third batch of 55 6th Class steam locomotives in service, which would be designated Class 6B on the South African Railways (SAR) in 1912.[1][2][3][4]

The Type XC1 entered service as tenders to these locomotives. More entered service in 1898, as tenders to the Oranje-Vrijstaat Gouwerment-Spoorwegen (OVGS) 6th Class L3, Class 6E on the SAR. These two Classes were built by Dübs and Company, Neilson and Company, Neilson, Reid and Company and Sharp, Stewart and Company.[1][2][3]

Rebuilding

Between 1912 and 1941, probably c. 1930, several of the Type XC1 tenders were completely rebuilt by the SAR, by mounting a completely new upper structure on the existing underframe, with larger water tanks and a larger coal capacity. The water capacity was increased from 2,600 to 2,850 imperial gallons (11,800 to 13,000 litres) and the tender sides were built up to increase the coal capacity from 5 long tons 10 hundredweight (5.6 tonnes) to 8 long tons (8.1 tonnes). These rebuilt tenders had a more modern appearance, with smooth sides all the way to the top. They were designated Type XE.[1][2]

Letter codes

Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR.[2]

The first letter of the tender type indicates the classes of engines to which it can be coupled. The "X_" tenders could be used with the following locomotive classes:[2]

The second letter indicates the tender's water capacity. The "_E" tenders had a capacity of between 2,800 and 2,855 imperial gallons (12,700 and 13,000 litres).[2]

A number, when added after the letter code, indicates differences between similar tender types, such as wheelbase or coal bunker capacity.[2]
