The South African type TJ tender was a steam locomotive tender from the pre-Union era in the Natal Colony.

The Type TJ tender first entered service in 1909, as tenders to the first five Class B 4-8-2 Mountain type steam locomotives which were acquired by the Natal Government Railways in that year. These locomotives were designated Class 3 on the South African Railways in 1912.

Type TJ tenders were built in 1909 and 1910 by the North British Locomotive Company (NBL) and the Natal Government Railways (NGR).

The NGR placed its first five Class B Mountain type locomotives in service in 1909. The locomotive and tender were designed by NGR Locomotive Superintendent D.A. Hendrie and built by NBL. Known as the Hendrie D, but officially designated Class B on the NGR, it was the first true Mountain type locomotive in the world. The Type TJ first entered service as tenders to these five locomotives. More entered service the following year, as tenders to the 21 NGR Class B Mastodon type locomotives of 1910, known as the Improved Hendrie B, and two NGR Class A Pacific type Hendrie A locomotives which were built in the Durban workshops of the NGR.

Another 25 Class B Mountain type locomotives entered service on the NGR in 1911, but these were delivered with Type TM tenders which had a larger coal and water capacity.

The tender had a coal capacity of 6 long tons (6.1 tonnes), a water capacity of 3,500 imperial gallons (15,900 litres) and a maximum axle load of 10 long tons 5 hundredweight (10,410 kilograms).

In the South African Railways (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.

In 1912, the SAR grouped and renumbered these NGR Classes A and B locomotives into three separate classes, according to wheel arrangement. Only these three classes were delivered new with Type TJ tenders. Bearing in mind that tenders could and did migrate between engines, the Type TJ tenders should have been numbered in the number ranges as shown.
