In 1891 and 1892 the Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij of the Zuid-Afrikaansche Republiek (Transvaal Republic) placed twenty-four tank locomotives with a 0-4-2 wheel arrangement in service. Since the railway classified its locomotives according to their weight, these locomotives were known as the 19 Tonners. ==Manufacturers== The first ten of eventually twenty-four tank locomotives with a 0-4-2 wheel arrangement, built in two batches of five by Emil Kessler’s Maschinenfabrik Esslingen in 1890, were placed in service by the Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij (NZASM) in 1891 and numbered in the range from 21 to 30. Since the NZASM classified its locomotives according to their weight, these locomotives were known as .〔 The 19 Tonners were equipped with Allan link valve gear, mounted externally and driven by eccentric sheaves that were mounted on a return crank.〔 Since they proved to be useful locomotives, an order for six more of the type was placed with Machinefabriek Breda voorheen Backer & Rueb (Breda machine factory, formerly Backer & Rueb). They were built in 1891 and 1892 and were numbered in the range from 15 to 20, but for some reason, possibly their delivery sequence, their numbering was not in the same sequence as their works numbers.〔 Eight more 19 Tonners were delivered from Maschinenfabrik Esslingen in 1892, numbered in the range from 31 to 38.〔 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「NZASM 19 Tonner 0-4-2T」の詳細全文を読む スポンサード リンク
