In SAR, Spoornet and Transnet Freight Rail (TFR) service, the Class worked on most mainlines and some unelectrified branchlines in the central, eastern, northern and northeastern parts of the country. From at least 1988 until at least 1992, the National Railways of Zimbabwe (NRZ) hired type GT26MC Class locomotives from the SAR and later Spoornet. At least one Class locomotive, no. , also served on lease in Zimbabwe and was observed there in September 1992. NLPI Limited, abbreviated from New Limpopo Projects Investments, a Mauritius-registered company, specialises in private sector investments by using the build-operate-transfer (BOT) concept. It had three connected railway operations in Zimbabwe and Zambia, which formed a rail link between South Africa and the Democratic Republic of Congo. In Zambia, the RSZ locomotive fleet included former ZR locomotives, but the rest of the locomotive fleet of all three operations consisted of South African GM-EMD Classes , and and GE Classes 35-000 and 35-400 locomotives from Spoornet and later TFR. These locomotives were sometimes marked or branded as either BBR or LOG or both, but their status, whether leased or loaned, was unclear since they were still on the TFR roster and still often worked in South Africa as well. Class locomotives which served with NLPI include the locomotives annotated "NLPI" in the "disposition" column in the table below. Zambia Railways, the state-owned holding company, resumed control of the Zambian national rail network on 11 September 2012. This followed the government's decision to revoke the operating concession awarded to RSZ after Finance Minister Alexander Chikwanda claimed that RSZ had "blatantly disregarded the provisions of the agreement" and had been "acting in a manner prejudicial to the interests of Zambians”. In 1979, one Class locomotive was delivered new to Iscor's Newcastle steel works in Natal, numbered . The works numbers of the Class as well as their known disposal and deployment are displayed in the table. The Class 34-800 were all 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 them began to be repainted in the Spoornet orange livery with a yellow and blue chevron pattern on the buffer beams.
