In 1931 three narrow gauge Class NG15 locomotives with a 2-8-2 Mikado type wheel arrangement, similar in design to their existing Class Hd and Class NG5 locomotives, were acquired for the Otavi Mining and Railway Company in South West Africa. More were purchased for the Otavi and for the Tsumeb Copper Corporation during the subsequent years, eventually bringing the total number of these locomotives up to twenty-one by 1958.〔 When the narrow gauge Otavi Railway was regauged to Cape gauge in 1960, all twenty-one locomotives were taken over by the South African Railways. They were transferred to the Eastern Cape for further service on the narrow gauge line from Port Elizabeth to Avontuur. ==Manufacturers== The Class NG15 2-8-2 Mikado type narrow gauge steam locomotive was designed by the South African Railways (SAR) and built by Henschel and Son for the Otavi Mining and Railway Company. The company operated a narrow gauge line across the Namib Desert from Swakopmund on the Atlantic coast to Tsumeb and Grootfontein in South West Africa (SWA, now Namibia). The first three locomotives were delivered in 1931, numbered in the range from NG17 to NG19, followed by three more in 1939, numbered in the range from NG117 to NG119.〔Henschel-Lieferliste (Henschel & Son works list), compiled by Dietmar Stresow〕 Ten more of these locomotives were built for the Otavi line by Société Franco-Belge and delivered in two batches of five in 1950 and 1953, numbered in the ranges from NG120 to NG124 and NG132 to NG136 respectively.〔 In 1958 five more of these locomotives, once again built by Henschel, were delivered to the Tsumeb Copper Corporation, numbered in the range from TC1 to TC5, for use by the SAR in terms of an agreement between the SAR and the Corporation. They were later renumbered in the SAR range from NG144 to NG148.〔〔〔South African Railways and Harbours Locomotive Diagram Book, 2’0” & 3’6” Gauge Steam Locomotives, 15 August 1941, as amended〕 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 NG15 2-8-2」の詳細全文を読む スポンサード リンク
