The South African Railways Class GMA 4-8-2+2-8-4 of 1954 is an articulated steam locomotive. Between 1954 and 1958 the South African Railways placed one hundred and twenty Class GMA branchline and Class GMAM mainline Garratt articulated steam locomotives with a 4-8-2+2-8-4 Double Mountain type wheel arrangement in service. This was the most numerous Garratt class in the world.〔South African Railways and Harbours Locomotive Diagram Book, 2’0” & 3’6” Gauge Steam Locomotives, 15 August 1941, as amended〕〔〔 ==Manufacturers== The light rail branchline Class GMA and mainline Class GMAM Garratt locomotives were a development of the large Class GM branchline locomotive that was introduced on the South African Railways (SAR) in 1938. Designed in 1952 under the supervision of L.C. Grubb, Chief Mechanical Engineer (CME) of the SAR from 1949 to 1954, an order for the first twenty-five of these locomotives was placed with Henschel and Son in Germany. They were built in 1953 and were delivered and placed in service in 1954, numbered in the range from 4051 to 4075.〔Henschel-Lieferliste (Henschel & Son works list), compiled by Dietmar Stresow〕 A second batch of thirty-five locomotives was delivered by Beyer, Peacock and Company (BP) in 1956. Of these, twenty-three were built by BP and numbered in the range from 4076 to 4098, while the other twelve, numbered in the range from 4099 to 4110, had been subcontracted by BP to the North British Locomotive Company (NBL). These twelve were therefore allocated works numbers by BP as well as by NBL.〔〔North British Locomotive Company works list, compiled by Austrian locomotive historian Bernhard Schmeiser〕〔North British Locomotive Co. (from J. Lambert)〕 This was followed by a third and final batch of sixty locomotives in 1958. Of these, thirty were delivered by BP, of which only ten, numbered in the range from 4121 to 4130, had actually been built by BP. The other twenty, numbered in the ranges from 4111 to 4120 and 4131 to 4140, had once again been subcontracted by BP to NBL. These twenty were therefore also allocated works numbers by BP as well as by NBL. The order for the last thirty locomotives, numbered in the range from 4141 to 4170, had again been placed with Henschel in Germany.〔〔〔〔〔〔 The builders, works numbers and year built of these locomotives are listed in the table.〔〔〔〔〔 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 GMA 4-8-2+2-8-4」の詳細全文を読む スポンサード リンク
