The Cape Government Railways 3rd Class 4-4-0 of 1903 is a South African steam locomotive from the pre-Union era in the 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. ==Manufacturer== The last eight Wynberg Tender passenger locomotives for suburban service in Cape Town were introduced on the Cape Government Railways (CGR) in 1903. They were also built by Sharp, Stewart and Company, but it appears that their numbering was used as an opportunity to perform some gap-filling on the numbering roster.〔〔 These locomotives were very similar in design and appearance to the previous batch of six of 1901, but larger and more powerful. The main differences were: * The wheelbase of the coupled wheels, the engine itself and the engine-and-tender were longer. * As a result, the overall length was longer. * The locomotive was heavier, with a heavier axle load, engine and tender weight. * The tender had a larger water capacity. * The boiler pitch was raised. * The maximum boiler pressure was raised from . * The grate area and the tube- and firebox heating areas were larger. * The cylinder bore was increased. * As a result, the tractive effort was raised from at 75% boiler pressure.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「CGR 3rd Class 4-4-0 1903」の詳細全文を読む スポンサード リンク
