The '''Cape Government Railways 3rd Class 4-4-0 of 1903''' was a South African steam locomotive from the pre-[[Union of South Africa|Union]] era in the [[Cape Colony|Cape of Good Hope]].
In 1903, the Cape Government Railways placed the last eight 3rd Class ''Wynberg Tender'' locomotives with a 4-4-0 American type wheel arrangement in suburban service in Cape Town. While they appeared to be virtually identical to the locomotives of 1901 at first glance, they were heavier and more powerful.<ref name="Holland 1">{{Holland-Vol 1|pages=59-61}}</ref><ref name="Paxton-Bourne">{{Paxton-Bourne|page=18}}</ref><ref name="SAR&H Jan 1944">Espitalier, T.J.; Day, W.A.J.

==Manufacturer== [[File:H.M. Beatty.jpg|thumb|left|150px|H.M. Beatty]] The last eight {{nowrap|3rd Class}} ''Wynberg Tender'' passenger locomotives for suburban service in Cape Town were introduced on the [[Cape Government Railways]] (CGR) in 1903. Like the ''Wynberg Tenders'' of 1901, they were built by [[Sharp, Stewart and Company]]. It would appear that their numbering was used as an opportunity to perform some gap-filling on the CGR engine number roster.<ref name="Holland 1"/><ref name="Paxton-Bourne"/>
These locomotives were very similar in design and appearance to the six [[CGR 3rd Class 4-4-0 1901|CGR 3rd Class 4-4-0 engines of 1901]], but Cape Government Railways Chief Locomotive Superintendent H.M. Beatty had revisited his earlier designs which resulted in a larger and more powerful locomotive. The main differences were: * The wheelbase of the coupled wheels, the engine itself and the engine-and-tender were longer and, as a result, the overall length was longer. * The engine and tender were both heavier, with a heavier axle load. * The tender had a larger water capacity. * The boiler pitch was raised. * The maximum boiler pressure was raised from {{convert|165|to|180|psi|kPa|0|abbr=off}}. * The grate area and the tube and firebox heating areas were larger. * The cylinder bore was increased and, as a result, the tractive effort was increased from {{convert|14310|to|16540|lbf|kN|1|abbr=off}} at 75% boiler pressure.<ref name="Holland 1"/>
==Service==
===Cape Government Railways=== These locomotives were also known as ''Wynberg Tenders''. They were fast and reliable and performed well on the [[Simon's Town]] line. Some were later transferred to [[Port Elizabeth]], where they were employed on the inter-urban passenger trains to [[Uitenhage]].<ref name="Holland 1"/><ref name="SAR&H Jan 1944"/>
===South African Railways=== When the [[Union of South Africa]] was established on 31 May 1910, the three Colonial government railways (CGR, [[Natal Government Railways]] and [[Central South African Railways]]) were united under a single administration to control and administer the railways, ports and harbours of the Union. Although the South African Railways and Harbours came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways were only implemented with effect from 1 January 1912.<ref name="SAR History">''The South African Railways – Historical Survey''. Editor George Hart, Publisher Bill Hart, Sponsored by Dorbyl Ltd., Published c. 1978, p. 25.</ref><ref name="SAR Renumber"/>
In 1912, even though they were less than ten years old, these locomotives were also considered obsolete by the South African Railways (SAR), designated Class 03 and renumbered by having the numeral "0" prefixed to their existing numbers. In SAR service, they continued to work suburban trains in Cape Town. Some were later transferred to [[Germiston]], where they were adapted to work the push-pull railmotor trains which ran between Germiston and Wattles until that line was electrified.<ref name="Holland 1"/>
Despite being considered obsolete, all eight engines survived until c. 1918. Two were withdrawn from service between 1918 and 1931, while the rest survived in service until after 1931.<ref name="Paxton-Bourne"/><ref name="SAR Renumber">''Classification of S.A.R.
