The fuel crisis has spurred the plan to electrify a distance of 525 kilometers of South African Railways (SAR), i.e., the coal line from Witbank area to Richards Bay. Use will be made of ac rather dc because there are load restrictions with the 3 k dc system, and loads of 3,000 or 4,000 tonnes or more cannot be handled economically. The changeover is expected to save 30 percent and 35 percent on the fixed installation compared with dc. The coal line has been designed for loads of 6,000 t, and electrification has now started using a 25 kV system. A further section of SAR now handling 8,000 t of ore may be electrified and designed for ac working. The history of the electrification of SAR routes is briefly reviewed and future plans are outlined. Computer programs have been drawn up for SAR's requirements which will be utilized to determine a suitable locomotive and track design; the locomotive must be capable of handling gradient of 1:66.
