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

Tender (rail) vehicle for carrying a steam locomotives supply of fuel and water

A tender or coal-car is a special rail vehicle hauled by a steam locomotive containing its fuel and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive (itself) instead are called tank locomotives.

Contents

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]

South African type TJ tender

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

South African Class 3 4-8-2 class of 30 South African 4-8-2 locomotives

The South African Railways Class 3 4-8-2 of 1909 was a steam locomotive from the pre-Union era in the Colony of Natal.

The South African Railways Class 2C 4-6-2 of 1910 was a steam locomotive from the pre-Union era in the Colony of Natal.

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]

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

South African Class 3B 4-8-2 class of 10 South African 4-8-2 locomotives

The South African Railways Class 3B 4-8-2 of 1912 was a steam locomotive.

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]

North British Locomotive Company defunct British locomotive manufacturer, active 1903–1962

The North British Locomotive Company was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company, Neilson, Reid and Company and Dübs and Company, creating the largest locomotive manufacturing company in Europe and the British Empire.

Rebuilding

From c. 1925, several of the Types TJ and TM tenders were completely rebuilt by the South African Railways (SAR) by mounting a new upper structure on the existing underframe. These rebuilt tenders had a more modern appearance, with flush sides all the way to the top of the coal bunker. They were designated Type TL. [5]

The program to rebuild several older tender types with new upper structures was begun by Colonel F.R. Collins DSO, who approved several of the detailed drawings for the work during his term in office as Chief Mechanical Engineer (CME) of the SAR from 1922 to 1929. It was continued by his successor, A.G. Watson. [1] [2] [5]

Characteristics

In the case of tenders rebuilt from the Type TJ, the rebuilding resulted in a tender with larger water tanks, with the capacity increased from 3,500 to 3,900 imperial gallons (15,900 to 17,700 litres), and a larger coal capacity, increased from 6 long tons (6.1 tonnes) to 8 long tons 15 hundredweight (8.9 tonnes). [2] [5]

In the case of tenders rebuilt from the Type TM, the water capacity was reduced from 4,000 to 3,900 imperial gallons (18,200 to 17,700 litres), 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] [5]

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 "T_" tenders could be used with the locomotive classes as shown, although the engine drawbar had to be replaced to suit the target engine in some cases. [2]

The second letter indicates the tender's water capacity. The "_L" tenders had a capacity of 3,900 imperial gallons (17,700 litres; 4,680 US gallons). [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), by extending the top of the coal bunker rearwards. [2]
