the Beit Bridge to Bulawayo line in Zimbabwe. Since February 2004 NLPI Logistics (NLL or LOG) has been operating between Bulawayo and Victoria Falls on the Zimbabwe-Zambia border. Since February 2003, the Railway Systems of Zambia (RSZ) operated on the former Zambia Railways (ZR) line from Victoria Falls to Sakania in the Congo. In Zambia, the RSZ locomotive fleet included former Zambia Railways locomotives, but the rest of the locomotive fleet of all three operations consisted of South African GM-EMD Classes , and and GE Classes and locomotives, supplied by Transnet Freight Rail (TFR). These locomotives were sometimes marked 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. The locomotives did not appear to be restricted to work in any one of the three operations sections and have been observed being transferred between Zimbabwe and Zambia across the bridge at Victoria Falls as required. Class locomotives which serve with NLPI include the locomotives annotated "NLPI" in the "leased or loaned" column in the table. Zambia Railways, the state-owned holding company, resumed control of the Zambian national rail network on 11 September 2012. This followed the Zambian government’s decision to revoke the operating concession which had been 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”. Tanzania Railways Ten Class locomotives were leased to Tanzania Railways, where they were regauged to Metre gauge. Locomotives which served there include the ones annotated "Tanzania" in the "leased or loaned" column in the table. Zaire Class locomotives were also leased to Société Nationale des Chemins de Fer Zaïrois (SNCZ) in Zaire and were occasionally used by Zambia Railways on their journey north through Zambia. This was done with the agreement of SNCZ, who stipulated that they could only haul transit traffic for Zaire. Class locomotives which were noted in such service through Zambia were, amongst others, two unidentified locomotives at Kabwe in August 1981, no. 35-464 at Choma in May 1985, no. 35-451 at Lusaka in February 1986, and another unidentified locomotive at Lusaka in May 1990, all under power on northbound goods.
