In July 2011, the first of the 209 locally built locomotives for Transnet Freight Rail and two more customers was rolled out at the Koedoespoort shops in Pretoria.

Sibanye was a South African Black Economic Empowerment (BEE) front company, dealing with locomotives and spare parts.

[11] Upon completion of the first two TFR orders, the TE production line at Koedoespoort continued to manufacture C30ACi diesel-electric locomotives for customers elsewhere on the African continent.

Since the C30ACi was the latest state-of-the-art GE locomotive specifically designed and built for Cape gauge which is widely used in West and Southern Africa, potential customers may include Ghana, Nigeria, Congo-Brazzaville, Democratic Republic of the Congo, Angola, Mozambique, Malawi, Zambia, Botswana, Namibia, South-western Tanzania and Zimbabwe.

It met with the emission standards for brake-specific nitrogen oxides, unburned hydrocarbons, carbon monoxide and particulate matter.

The locomotives, numbered in the range from F123-0100 to F123-0600, were painted in a dark blue livery with yellow sills and handrails.

The Mozambican locomotives are 9 tonnes lighter than those of TFR, with bogies fabricated by UGL in Australia and different traction motors.

In South Africa mixed electric and diesel-electric consists are unique to the Orex line, necessitated by the huge voltage drops which can occur as a result of the long distance between some of the sub-stations along the route.
