The first 10 units of Transnet Freight Rail's newest diesel locomotives, the Class 43 GE C30-Aci, were built in the USA (see photo ID 349791). The remaining 90 units are being built by Transnet Rail Engineering (TRE) at their Koedoespoort works in Pretoria, where loco 027 is seen on the production line. TRE are currently producing one complete locomotive every five days, with plans to reduce this to 3 days. These are the first AC traction diesel electric locomotives in sub-Saharan Africa.
