The South African Railways Class 15C 4-8-2 of 1925 is a steam locomotive. In 1925 the South African Railways placed two American-built Class 15C steam locomotives with a 4-8-2 Mountain type wheel arrangement in service. Another ten locomotives were ordered and delivered a year later. ==Manufacturer== The Class 15C 4-8-2 Mountain type steam locomotive was built by Baldwin Locomotive Works (BLW) in 1925 and 1926, conforming to South African Railways (SAR) requirements as far as practicable, but also incorporating the latest American railway engineering practices. These locomotives introduced several features which were new to the SAR at the time, such as top feeds to the boiler, self-cleaning smokeboxes, Sellar’s drifting valves and grease lubrication. Their fireboxes were equipped with siphon tubes to support the brick arch and to improve circulation.〔〔 Its boiler was larger in proportion than that of any existing SAR locomotive and was also raised higher than that of anything else in service at that time. The locomotive’s size quickly earned it the nickname "Big Bill", while its contemporary Class 16D 4-6-2 Pacific type that arrived from the same builders in the same shipment was nicknamed "Big Bertha".〔 The first two locomotives, numbers 2060 and 2061, were erected at the Salt River shops and put to work on the line from Cape Town to Touws River. They performed well, were comparatively trouble-free and good steamers, and capable of handling a heavy load exceeding that of any other locomotive that had been employed on this section to date. Because of the good results obtained from these two locomotives, an order was placed with Baldwin for another ten that were delivered in 1926, numbered in the range from 2062 to 2071.〔 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「South African Class 15C 4-8-2」の詳細全文を読む スポンサード リンク
