The South African type TL tender was a steam locomotive tender.
Type TL tenders were rebuilt from Type TJ and Type TM tenders which had entered service between 1909 and 1912. The rebuilding resulted in a tender with a larger coal bunker.[1][2]
Origin
Type TJ tenders entered service on the Natal Government Railways (NGR) in 1909 and 1910, as tenders to the first five locomotives of the Class B 4-8-2 of 1909 and the Classes A 4-6-0 and B 4-8-0 of 1910.[1][2][3]
Type TM tenders entered service on the NGR and South African Railways (SAR) in 1911 and 1912, as tenders to the last 25 locomotives of the NGR Class B 4-8-2 and the SAR Class 3B.[1][2][4]
These locomotives and tender were designed by NGR Locomotive Superintendent D.A. Hendrie and built by the North British Locomotive Company and the NGR.[1][2][3][4]
Rebuilding
Between 1912 and 1941, probably c. 1930, several of the Types TJ and TM tenders were rebuilt by the SAR, by mounting a completely new upper structure on the existing underframe. These rebuilt tenders, designated Type TL, had a more modern appearance with smooth sides all the way to the top.[1][2]
- In the case of the Type TJ, the rebuilding resulted in a tender with larger water tanks, with the capacity increased from Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)., and a larger coal capacity, increased from 6 long tons (6.1 tonnes) to 8 long tons 15 hundredweight (8.9 tonnes).[2]
- In the case of the Type TM, the water capacity was reduced from Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)., while the coal capacity was increased from 8 long tons 5 hundredweight (8.4 tonnes) to 8 long tons 15 hundredweight (8.9 tonnes).[1][2]
Letter codes
The first letter of the tender type indicates the classes of engines to which it can be coupled. The "T_" tenders could be used with the locomotive classes as shown below, although the engine drawbar had to be replaced to suit the target engine in some cases.[2]
- NGR Class B 4-8-0 of 1910, SAR Class 1A
- NGR Class A 4-6-2 of 1910, SAR Class 2C
- NGR Class B 4-8-2 of 1909, SAR Class 3
- SAR Class 3B
- SAR Class MC
The second letter indicates the tender's water capacity. The "_L" tenders had a capacity of Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)..[2]
A number, when added after the letter code, indicates differences between similar tender types, such as wheelbase or coal bunker capacity.[2]
Modification
Some Type TL tenders were subsequently modified to increase their coal capacity from 8 long tons 15 hundredweight (8.9 tonnes) to 11 long tons 15 hundredweight (11.9 tonnes).[2]
