The South African Class 35-000 type GE U15C diesel-electric locomotive was designed and built for the South African Railways (SAR) by General Electric (GE) and imported. The first batch of fifty locomotives was delivered in 1972, numbered in the range from 35-001 to 35-050, with the first locomotives arriving in March. These were followed by a second batch of twenty in 1973, numbered in the range from 35-051 to 35-070. The last locomotives arrived in May 1973.
Class 35 series
GE and GM-EMD designs
The Class 35 locomotive series consists of four sub-classes, the GE Classes 35-000 and 35-400 and the General Motors Electro-Motive Division (GM-EMD) Classes 35-200 and 35-600. Both these manufacturers also produced locomotives for the South African Classes 33, 34 and 36.
The locomotive has interlinked bogies, hence the "Co+Co" wheel arrangement classification. The linkage is usually hidden from view by the saddle-shaped fuel tank.
With the GE U15C Class 35 locomotives, the Class 35-000 and 35-400 are visually indistinguishable from each other. An externally visible modification that is done during major overhauls is the addition of a saddle hood astride the hump on the long hood behind the cab. By 2013 this modification had been done on a large number of Class 35-000s, but not yet on any Class 35-400s.
South African Railways
The Class 35 is South Africa’s standard branchline diesel-electric locomotive. GE Class 35-000s were designed for light rail conditions and they work on most branchlines in the central, western, southern and southeastern parts of the country. In the Western Cape they work out of Cape Town on the branchlines to Bitterfontein, Saldanha and Caledon, and out of Worcester to George. A threesome is allocated to the Swartkops depot in Port Elizabeth from where they work the Passenger Rail Agency of South Africa (PRASA) MetroRail commuter trains to Uitenhage.
New Limpopo Projects Investments Limited (NLPI), a Mauritius registered company, specialises in private sector investments using the build-operate-transfer (BOT) concept. It has three connected railway operations in Zimbabwe and Zambia that form a rail link between South Africa and the Democratic Republic of the Congo.
- The Beitbridge Bulawayo Railway (BBR), commissioned on 1 September 1999, operates the Beit Bridge to Bulawayo line in Zimbabwe.
- As from February 2004 NLPI Logistics (NLL or LOG) operates between Bulawayo and Victoria Falls on the Zimbabwe-Zambia border.
- As from February 2003 the Railway Systems of Zambia (RSZ) operates on the former Zambian Railways (ZR) from Victoria Falls to Sakania in the Congo.
In Zambia the RSZ locomotive fleet includes former ZR locomotives, but the rest of the locomotive fleet of all three operations consist of GM-EMD Classes 34-200, 34-600 and 34-800 and GE Classes 35-000 and 35-400 locomotives from Transnet Freight Rail (TFR). These locomotives are sometimes marked or branded as either BBR or LOG or both, but their status, whether leased or loaned, is unclear since they are still on the TFR roster and still often work in South Africa as well. The locomotives do not appear to be restricted to working in any one of the three operations sections and have been observed being transferred across the bridge at Victoria Falls between Zimbabwe and Zambia as required.
The Class 35-000 builder’s works numbers and NLPI allocation are set out in the table.
The main picture shows number 35-020 in the Transnet Freight Rail livery and with a saddle hood in the Orex Yard at Saldanha on 10 February 2013. Other liveries that were applied to Class 35-000 locomotives are illustrated below. The last picture displays the top of a locomotive with a saddle hood. It was involved in a major derailment near Moorreesburg on 7 June 2007 when the track roadbed was washed away during heavy rain and flooding.
