The South African Railways Class 7E of 1978 is an electric locomotive. In 1978 and 1979 the South African Railways placed one hundred Class 7E electric locomotives with a Co-Co wheel arrangement in mainline service. They were the first 25 kV AC locomotives to enter service in South Africa.〔South African Railways Index and Diagrams Electric and Diesel Locomotives, 610mm and 1065mm Gauges, Ref LXD 14/1/100/20, 28 January 1975, as amended〕 ==Manufacturer== The 25 kV AC Class 7E electric locomotive was designed for the South African Railways (SAR) by the 50 c/s Group, consisting of ACEC of Belgium, AEG-Telefunken and Siemens of Germany, Alsthom-Atlantique and Société MTE of France, and Brown Boveri of Switzerland. They were built by Union Carriage and Wagon (UCW) in Nigel, Transvaal, who was the sub-contractor for mechanical components and assembly. One hundred Class 7E locomotives were delivered in 1978 and 1979, numbered in the range from E7001 to E7100. Beginning with the Class 7E, the SAR numbering practice for electric locomotives was changed to make the class number a part of the locomotive’s number. From the Class 1E through to the last of the Class 6E1 series of locomotives, all electric locomotives were numbered sequentially in the number range from E1 to E2185, with twelve numbers in the range skipped.〔 UCW did not allocate builder’s numbers to the locomotives it built for the SAR, but used the SAR unit numbers for their record keeping.〔 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 7E」の詳細全文を読む スポンサード リンク
