The South African Railways Class 19B 4-8-2 of 1930 is a steam locomotive. In 1930 the South African Railways placed fourteen Class 19B steam locomotives with a 4-8-2 Mountain type wheel arrangement in service. One of them was later reboilered and reclassified to Class 19BR.〔South African Railways and Harbours Locomotive Diagram Book, 2’0” & 3’6” Gauge Steam Locomotives, 15 August 1941, pp21 & 21A, as amended〕 ==Manufacturer== The South African Class 19B 4-8-2 Mountain type steam locomotive was a later model of the original Class 19. It was virtually identical to the Class 19 apart from the wheelbase of the front bogie, which had been increased from to in order to improve the clearance between the cylinders and the bogie wheels, since the bogie wheels of predecessors Class 19 and Class 19A fouled the cylinder covers on sharp curves. Because of this difference they were classified as Class 19B.〔〔(Secunda, Sasol Synfuels East, ex-SAR Class 19B No 1413 )〕 They were built in Germany by Berliner Maschinenbau AG (BMAG), the former L. Schwartzkopff, and delivered in 1930, numbered in the range from 1401 to 1414. All but one were built with Walschaerts valve gear.〔〔 Number 1414 was equipped with Caprotti valve gear as an experiment. After thirteen years, however, the Caprotti valve gear was removed at the Uitenhage workshops in 1943 and replaced with Walschaerts valve gear. The experiment did result in the successor Class 19C being built with Rotary Cam Poppet valve gear.〔 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 19B 4-8-2」の詳細全文を読む スポンサード リンク
