A 3000 V DC NETWORK COPES WITH OVERLOADING PROBLEMS

Fifty years after completion of South Africa's first mainline electrification, parts of SAR's 4,500-km network of 3.00 V DC lines have had to be heavily reinforced to permit operation of 7,300-ton trains hauled by six units. This is in part why the the 1,625 route km authorized for immediate electrification after the 1973 oil crisis includes two major segments at 25 kV AC where fixed equipment is about half the cost of 3,000 V DC installations for the same heavy-load situation.
