TRE will assemble 85 of the 3MW Locomotives, which are equipped for operation on 25kV ac and 3kV dc electrification systems.

The locomotives are being built by CSR E-loco Supply, a 70:30 joint venture between CSR Zhuzhou and South African partner Matsetse Basadi. The contract with TFR specifies a target of 60.5% for localised content.

Initially TFR assembled locomotives with bodyshells supplied by CSR, but these are now being fabricated in South Africa.
