South African Class 8C 4-8-0

The South African Class 8C 4-8-0 of 1903 is a South African steam locomotive from the pre-Union era in the Transvaal.

In 1903, soon after the establishment of the Central South African Railways, a second batch of thirty Cape 8th Class 4-8-0 Mastodon steam locomotives were ordered and placed in service as the Class 8-L3, immediately following upon a previous order in that same year for a variation on the same locomotive type. In 1912, when they were assimilated into the South African Railways, they were renumbered and reclassified to Class 8C.^[2][5][6]

Manufacturer

Upon the establishment of the Central South African Railways (CSAR) in July 1902, soon after the end of the Second Freedom War, Chief Locomotive Superintendent P.A. Hyde became the custodian of a mixed bag of locomotives inherited from the Imperial Military Railways (IMR). These included locomotives that originated with the Selati Railway, the Nederlandsche Zuid-Afrikaansche Spoorweg-Maatschappij (NZASM), the Pretoria-Pietersburg Railway (PPR) and the Oranje-Vrijstaat Gouwerment Spoorwegen (OVGS).^[7]

The comparatively small number of serviceable locomotives that were immediately available for service, compounded by the poor condition of many of the original NZASM, PPR, Selati and OVGS locomotives and an expected post-war increase in traffic, led to an order for altogether sixty new steam locomotives. They were to be built in two variations, to the specifications of the 8th Class 4-8-0 Mastodon type that was designed by H.M. Beatty, the Chief Locomotive Superintendent of the Cape Government Railways (CGR) from 1896 to 1910.^[2][6]

Orders were placed with Neilson, Reid and Company in 1903, but while they were being built, Neilson, Reid amalgamated with Dübs and Company and Sharp, Stewart and Company to form the North British Locomotive Company (NBL). As a result, the thirty locomotives of the second batch, numbered in the range from 471 to 500, were all delivered as built by the North British Locomotive Company (NBL) at the Hyde Park shops of the former Neilson, Reid.^[2][6]

They differed from the first batch of the same order only by not being equipped with Drummond water tubes in the fireboxes. To differentiate them from the Class 8-L1 and the Drummond tube-equipped Class 8-L2, these locomotives became the CSAR Class 8-L3. These were the last locomotives to be ordered by the CSAR that were built to the design of another railway.^[2][6]

Class 8 sub-classes

The Union of South Africa was established on 31 May 1910, in terms of the South Africa Act. One of the clauses in the Act required that the three Colonial Government railways, the CGR, the Natal Government Railways and the CSAR, also be united under one single administration to control and administer the railways, ports and harbours of the Union. While the South African Railways (SAR) came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways required careful planning and was only implemented with effect from 1 January 1912.^[5][8]

In 1912 these thirty locomotives were renumbered in the range from 1162 to 1191 and reclassified to Class 8C on the SAR.^[4][5][6]

These locomotives, together with the CSAR’s Class 8-L1 and 8-L2 4-8-0 Mastodon locomotives and all the CGR’s 8th Class 2-8-0 Consolidations and 4-8-0 Mastodons, were grouped into ten different sub-classes by the SAR. The 4-8-0 locomotives became SAR Classes 8 and 8A to 8F and the 2-8-0 locomotives became Classes 8X to 8Z.^[3]

Modification

During A.G. Watson’s term as the Chief Mechanical Engineer (CME) of the SAR from 1929 to 1936, many of the Class 8 to Class 8F locomotives were equipped with superheated boilers, larger bore cylinders and either inside or outside admission piston valves. The outside admission valve locomotives had their cylinder bore increased from 18.5 inches (470 millimetres) to 19 inches (483 millimetres) and retained their existing SAR classifications, while the inside admission valve locomotives had their cylinder bore increased to 20 inches (508 millimetres) and were reclassified by having a "W" suffix added to their existing SAR classifications.^[3][6]

Of the Class 8C locomotives, seven were equipped with superheating, 19 inches (483 millimetres) bore cylinders and outside admission piston valves while retaining their Class 8C classification.^[3]

Five locomotives were equipped with superheating, 20 inches (508 millimetres) bore cylinders and inside admission piston valves, and were reclassified to Class 8CW.^[3]

The Class 8C and 8CW works numbers, renumbering and superheating modifications are shown in the table.^[1][3][5]

Service

In SAR service, the 4-8-0 Class 8 family of locomotives worked on every system in the country and in the 1920s became the mainstay of motive power on many branchlines. Their final days were spent in shunting service and by 1972 they were all withdrawn.^[6]
