Main article: South African steam locomotive tenders

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

The Type ZC tender first entered service in 1896, as tenders to the second version of the 7th Class 4-8-0 Mastodon type steam locomotive to be acquired by the Cape Government Railways. These locomotives were designated Class 7A on the South African Railways in 1912.^[1]^[2]^[3]

Manufacturers

Type ZC tenders were built between 1896 and 1913 by Dübs and Company, Kitson and Company, Neilson and Company, Neilson, Reid and Company, North British Locomotive Company and Sharp, Stewart and Company.^[1]

The original 7th Class locomotive and tender had been designed at the Salt River works of the Cape Government Railways (CGR) in Cape Town in 1892, under the supervision of H.M. Beatty, the CGR Western System's Locomotive Superintendent. Between 1896 and 1901, the CGR placed 46 more 7th Class locomotives in service, which would be designated Class 7A on the South African Railways (SAR) in 1912.^[1]^[2]^[3]

The Type ZC first entered service in 1896, as tender to these locomotives. Until 1913, all further 7th Class locomotives which were acquired by the CGR, Imperial Military Railways (IMR), Rhodesia Railways (RR) and New Cape Central Railway (NCCR), were delivered with Type ZC tenders.^[2]^[3]

A second version of the Type ZC, with a larger coal capacity, entered service on the NCCR as tenders to its 7th Class locomotives of 1899-1904 and 1913, which would respectively be designated Classes 7E and 7F on the SAR in 1925.^[2]^[3]

Classification

Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR and these tenders were designated Type ZC.^[1]^[3]^[4]

In the SAR years, tenders were numbered for the engines they were delivered with. In most cases, an oval number plate, bearing the engine number and 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.^[4]

Six locomotive classes were delivered new with Type ZC tenders, built by six manufacturers, and two versions of the Type ZC were built. The majority had a 5 long tons 10 hundredweight (5.6 tonnes) coal capacity, but those which were built for the NCCR had a 6 long tons 10 hundredweight (6.6 tonnes) coal capacity. Bearing in mind that tenders could and did migrate between engines, the tenders should have been numbered in the SAR number blocks as shown.^[2]^[3]^[4]

5½ long tons coal capacity

1896: CGR 7th Class of 1896, SAR Class 7A, numbers 988 to 1031.
1899: RR 7th Class, SAR Class 7D, numbers 1351 to 1355.
1900: IMR 7th Class, SAR Class 7B, numbers 949 and 1032 to 1058.
1902: CGR 7th Class of 1902, SAR Class 7C, numbers 1059 to 1068.

6½ long tons coal capacity

1899: NCCR 7th Class of 1899, SAR Class 7E, numbers 1344 to 1350.^[2]^[3]
1913: NCCR 7th Class of 1913, SAR Class 7F, numbers 1357 to 1359.^[2]^[3]

Letter codes

The first letter of the tender type indicates the classes of engines to which it can be coupled. The "Z_" tenders could be used with the following locomotive classes:^[3]

The second letter indicates the tender's water capacity. The "_C" tenders had a capacity of between 2,590 and 2,600 imperial gallons (11,770 and 11,820 litres).^[3]

A number, when added after the letter code, indicates differences between similar tender types, such as wheelbase or coal bunker capacity.^[3]

Modification and rebuilding

Modification

When the need arose, some shops or enginemen sometimes increased the coal capacity of tenders by makeshift means, such as constructing wooden extensions for the bunker sides. In the example depicted, the Cape of Good Hope Governor's train is shown arriving in Fort Beaufort behind CGR 7th Class no. 722 for the official opening of the railway station in 1904. The engine's Type ZC tender's sides had been raised by installing what appears to be planking, to allow a greater coal load. In addition, an open gondola-type goods truck between the tender and the passenger carriage is loaded with more coal and two workmen.

Rebuilding

Between 1912 and 1941, probably c. 1930, some of the Type ZC tenders which had entered service between 1896 and 1902, were rebuilt to Type ZE tenders. The rebuilding resulted in a tender with a larger water tank and larger coal bunker.^[2]^[3]
