into brackets welded onto the running board, they are easily removed. Electronic control system Beginning in 2010, some locomotives were equipped with electronic fuel injection and GE Bright Star control systems. On some of the first locomotives which were so modified, externally visible evidence of the modification is a raised middle portion of the long hood. All Bright Star-equipped locomotives emerged from this modification repainted in the Transnet Freight Rail livery. Service Class locomotives work on most mainlines and some branchlines in the central, western, southern and southeastern parts of the country. Some eventually joined the Class on the Sishen-Saldanha iron ore line to haul export ore from the open cast iron mines at Sishen in the Northern Cape to the harbour at Saldanha in the Western Cape. On the Sishen–Saldanha Orex line, GE Class 34 series diesel-electric locomotives run consisted to Class 9E and Class 15E electric locomotives to haul the 342-truck iron ore trains. Each truck has a 100-ton capacity and the trains are at least in length, powered by mixed consists of Class 9E and Class 15E electric and type GE U26C Class , , , and, from 2012, type GE C30ACi Class diesel-electric locomotives. In South Africa, mixed electric and diesel-electric consists are unique to the iron ore line. Works numbers The Class builder's works numbers are listed in the table. Liveries All but seven Class 34-900 locomotives were delivered in the SAR Gulf Red livery with signal red buffer beams, yellow side stripes on the long hood sides and a yellow V on each end. In the 1990s many of the Class 34-900 units began to be repainted in the Spoornet orange livery with a yellow and blue chevron pattern on the buffer beams. In the late 1990s many were repainted in the Spoornet blue livery with outline numbers on the long hood sides. After 2008 in the Transnet Freight Rail (TFR) era, many were repainted in the TFR red, green and yellow livery. The seven exceptions, numbers to , were painted in the SAR Blue Train livery and took the place of the five SAR Blue Train liveried Class locomotives, numbers to which were then all eventually repainted in Spoornet's orange livery. Some of the Class locomotives, numbers to , and , were later repainted in Spoornet's orange era Blue Train livery, while the other two, numbers and , received the Spoornet blue with
