The Spoornet Class 14E1 of 1994 is a South African electric locomotive. In December 1994 Spoornet took delivery of the last of ten locally manufactured Class 14E1 dual voltage electric mainline locomotives with a Bo-Bo wheel arrangement. They had been preceded in 1991 by three prototype Class 14E locomotives.〔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 dual voltage 3 kV DC and 25 kV AC Class 14E1 electric locomotive was designed by Consortium 14E, consisting of Siemens, ABB, AEG-Westinghouse, GEC and Alsthom-Atlantique, headed by Siemens. They were built for Spoornet by Union Carriage and Wagon (UCW) in Nigel, Transvaal, under licence to Swiss Locomotive and Machine Works (SLM) in Winterthur. Ten locomotives were delivered and placed in service by December 1994, numbered in the range from 14-101 to 14-110. The original order was placed for fifty locomotives. The first locomotives to be delivered were subjected to intensive trial runs on speed-freight trains in KwaZulu-Natal and the Free State, during which it was found not to be a suitable locomotive for the infrastructure on lines rated at 20 ton per axle. It caused some damage to points when travelling at in the Free State. When the first one to be delivered developed a vibration in the gear box, the order for fifty locomotives was summarily reduced to ten only, given the unsatisfactory trial results to date.〔Information supplied by Mr. Brian Clark, Krugersdorp〕
