The South African type ET1 tender was a steam locomotive tender.

Contents

Type ET1 tenders were modified and reclassified Type ET tenders, which had entered service as tenders to Class 15F 4-8-2 Mountain type steam locomotives in 1947 and 1948. The modification resulted in a tender with a larger coal capacity, but the same water capacity. [1] [2]

South African Class 15F 4-8-2 class of 255 South African 4-8-2 locomotives

The South African Railways Class 15F 4-8-2 of 1938 was a steam locomotive.

Origin

The Type ET tender first entered service in 1947, as tenders to the last batch of 100 Class 15F locomotives to enter service on the South African Railways (SAR). They were built by North British Locomotive Company to designs by Doctor M.M. Loubser, Chief Mechanical Engineer of the SAR from 1939 to 1949, and were equipped with mechanical stokers. [3] [4] [5]

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.

Modification

During the 1950s, some of the Type ET tenders were modified to enlarge their coal bunkers from 14 to 16 long tons (14.2 to 16.3 tonnes) capacity. These modified tenders were designated Type ET1. [1] [2]

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 can be coupled. The "E_" tenders were arranged with mechanical stokers and could be used with the locomotive classes as shown. [1] [2]

Mechanical stoker device for delivering coal to locomotive firebox

A mechanical stoker is a mechanical system that feeds solid fuel like coal, coke or anthracite into the furnace of a steam boiler. They are common on steam locomotives after 1900 and are also used on ships and power stations. Known now as a spreader stoker they remain in use today especially in furnaces fueled by wood pellets or refuse.

South African Class 25NC 4-8-4 class of 137 South African 4-8-4 locomotives with non-condensing tenders (50 new, 87 rebuilt from Class 25)

The South African Railways Class 25NC 4-8-4 of 1953 was a steam locomotive.

South African Class 26 4-8-4

The South African Railways Class 26 4-8-4 of 1981 is a steam locomotive.

The second letter indicates the tender's water capacity. The "_T" tenders had a capacity of between 5,587 and 6,000 imperial gallons (25,400 and 27,300 litres; 6,710 and 7,210 US gallons). [2]

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