The Class 39-000 project
In 2005, Transwerk, later renamed Transwerk, Transnet Rail Engineering (TRE) and in 2013 Transnet Engineering, commenced a project to rebuild existing locomotives to South African Class 39-000, Class locomotives for Spoornet. The Electro-Motive Diesel type EMD diesel-electric locomotives were to be rebuilt from South African Class 34-600, Classes and South African Class 34-800, type GT26MC and South African Class 37-000, Class type GT26M2C locomotives. The original locomotives had all been designed by Electro-Motive Diesel, General Motors Electro-Motive Division and had been built by General Motors South Africa (GMSA) in Port Elizabeth between 1974 and 1981. Suitable frames from wrecked locomotives were used.South African Railways Index and Diagrams Electric and Diesel Locomotives, 610mm and 1065mm Gauges, Ref LXD 14/1/100/20, 28 January 1975, as amended The rebuilding was done at the Transwerk shops in Bloemfontein. It was intended to produce one hundred Class , but in spite of the technical success of the TRE part of the project, rebuilding was halted after completing only five locomotives, allegedly due to higher than anticipated cost. Instead of rebuilding one hundred old locomotives, it was decided to rather continue the program by building fifty new Class locomotives.The new Class 39-200
The Class locomotives were built new from imported and locally produced components at the Koedoespoort TRE shops east of Pretoria, in collaboration with EMD. By October 2009, more than twenty locomotives had been built and were undergoing road testing. By April 2010, the last of the fifty locomotives came off the production line, thereby completing the building project in twelve months. They were numbered in the range from to .Railways Africa, 6 Apr 2010: Final 39-200 Rolls OutFeatures
Characteristics which distinguish the Class from the existing TFR diesel-electric locomotive fleet, which was more than three decades old at the time, are features such as EM2000 microprocessor control, 26% more maximum continuous tractive effort and 15% more tractive horsepower compared to a Class , and a Knorr-Bremse electronic brake rack (EBR) instead of the old pneumatic braking controls. The EM2000 control system featured in the Class is a proprietary EMD microprocessor-based system which offers improved performance and reliability compared with older locomotives. It manages all critical operating functions and greatly improves tractive effort, while its creep control attains high- and low-speed adhesion advantages.Service
The Class locomotives were placed in service on the line between the Mpumalanga Lowveld and northern KwaZulu-Natal, working from Lydenburg via Swaziland and Golela to the coal export harbour at Richards Bay.Illustration
All the Class locomotives were delivered in the Transnet Freight Rail livery.References
