The South African type ZE 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 ZE tenders were rebuilt from Type ZC tenders which had entered service between 1896 and 1902. The rebuilding resulted in a tender with a larger water tank and larger coal bunker. [1] [2]

South African type ZC tender

The South African type ZC tender was a steam locomotive tender from the pre-Union era in the Cape of Good Hope.

Origin

The original 7th Class locomotive and tender were designed in 1892 at the Salt River works in Cape Town, under the supervision of H.M. Beatty, the Cape Government Railways (CGR) Western System's Locomotive Superintendent at the time. [1] [2] [3]

South African Class 7 4-8-0 class of 38 South African 4-8-0 locomotives

The South African Railways Class 7 4-8-0 of 1892 was a steam locomotive from the pre-Union era in the Cape of Good Hope.

Cape Government Railways railway operator in the Cape Colony

The Cape Government Railways (CGR) was the government-owned railway operator in the Cape Colony from 1874 until the creation of the South African Railways (SAR) in 1910.

Type ZC tenders entered service as tenders to six 7th Class locomotive variants between 1896 and 1913, built by Dübs and Company, Kitson and Company, Neilson and Company, Neilson, Reid and Company, North British Locomotive Company and Sharp, Stewart and Company. [1] [2] [3] [4]

Dübs and Company defunct British locomotive manufacturer

Dübs & Co. was a locomotive manufacturer in Glasgow, Scotland, founded by Henry Dübs in 1863 and based at the Queens Park Works in Polmadie. In 1903 it amalgamated with two other Glasgow locomotive manufacturers to create the North British Locomotive Company.

Kitson and Company was a locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England.

Neilson and Company defunct British locomotive manufacturer

Neilson and Company was a locomotive manufacturer in Glasgow, Scotland.

Rebuilding

From c. 1925, several of the Type ZC tenders which had entered service with the Class 7A in 1896, the Class 7B in 1900 and the Class 7C in 1902, were completely rebuilt by the South African Railways (SAR), by mounting a new upper structure on the existing underframe, with larger water tanks and a larger coal capacity. 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 ZE. [1] [2]

South African Class 7A 4-8-0 class of 46 South African 4-8-0 locomotives

The South African Railways Class 7A 4-8-0 of 1896 was a steam locomotive from the pre-Union era in the Cape of Good Hope.

South African Class 7B 4-8-0 class of 29 South African 4-8-0 locomotives

The South African Railways Class 7B 4-8-0 of 1900 was a steam locomotive from the pre-Union era in Transvaal.

South African Class 7C 4-8-0 class of 10 South African 4-8-0 locomotives

The South African Railways Class 7C 4-8-0 of 1902 was a steam locomotive from the pre-Union era in the Cape of Good Hope.

The program to rebuild several older tender types with new upper structures was begun by Col 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, CME from 1929 to 1936. [5]

Distinguished Service Order UK military decoration

The Distinguished Service Order (DSO) is a military decoration of the United Kingdom, and formerly of other parts of the Commonwealth, awarded for meritorious or distinguished service by officers of the armed forces during wartime, typically in actual combat. Since 1993 all ranks have been eligible.

Characteristics

The rebuilt tender had a coal capacity which had been increased from 5 long tons 10 hundredweight (5.6 tonnes) to 8 long tons (8.1 tonnes) and a water capacity which had been increased from 2,600 to 2,850 imperial gallons (11,820 to 12,960 litres). [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 could be coupled. The "Z_" tenders could be used with the locomotive classes as shown. [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 (12,730 and 12,980 litres; 3,363 and 3,429 US gallons). [2]
