the TAZARA Railway and even the Zambian Copper Mines. In Zambia, the South African locomotives were mainly used on goods trains between Livingstone and Kitwe, sometimes in tandem with a ZR locomotive and occasionally also on passenger trains. The first period of hire lasted from October 1978 until about April 1981. Locomotives were selected from a pool of units in the Classes 33-400, and which were allocated by the Railways for hire to Zambia. The South African fleet in Zambia was never constant, since locomotives were continually exchanged as they became due back in South Africa for their three-monthly services. The pool of Class locomotives allocated by the Railways for hire to ZR included the locomotives annotated "Zambia" in the "allocation" column in the table. The first Class units to serve in Zambia were on hire by May 1980. They served there for less than a year, being employed on road work as well as shunting. By the end of March 1981 the last Class unit to remain there was no. 35-064 which was due to return to South Africa as soon as the last of ZR’s new Krupp-built diesel locomotives, no. , was delivered. NLPI Ltd. NLPI Limited, abbreviated from New Limpopo Projects Investments, is a Mauritius-registered company which specialises in private sector investments using the build-operate-transfer (BOT) concept. It had three connected railway operations in Zimbabwe and Zambia that formed a rail link between South Africa and the Democratic Republic of Congo. The Beitbridge Bulawayo Railway (BBR) was commissioned on 1 September 1999 and operates between Beit Bridge and Bulawayo 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 Zambian Railways (ZR) line from Victoria Falls to Sakania in the 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 34-200, and 34-800 and GE Classes and locomotives. These units 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. The units did not appear to be restricted to working in any one of the three
