Between 1893 and 1898 one hundred and seventy-five 46 Tonner tank steam locomotives were placed in service by the Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij in the Zuid-Afrikaansche Republiek. In 1899 twenty more were ordered, of which only two were delivered by the time the Imperial Military Railways took over all railway operations in the two Boer Republics during the South African War. The other eighteen locomotives in this order were delivered directly to the Imperial Military Railways, who diverted two of them to Lourenço Marques.〔〔 At the end of the war the survivors of these locomotives were taken onto the roster of the Central South African Railways, renumbered and reclassified to Class B, while the two in Mozambique were taken onto the roster of the Caminhos de Ferro de Mocambique. In 1912, when the remaining locomotives were assimilated into the South African Railways, they were renumbered again but retained their Class B classification.〔〔 ==Forerunners== In 1891 the Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij (NZASM, often shortened to ZASM) of the Zuid-Afrikaansche Republiek (ZAR) placed an order with Emil Kessler’s firm, the Maschinenfabrik Esslingen in Germany, for twenty 40 Tonner 0-6-2T tank steam locomotives. While these locomotives were satisfactory in service, the trailing wheels initially proved troublesome owing to insufficient sideways freedom of movement when traversing curves.〔 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 B 0-6-4T」の詳細全文を読む スポンサード リンク
