South African Class 21E Coal Terminal. They work directly from the coal mines around Ermelo, running under 3 kV DC catenary. The dual voltage Class 21E locomotives can therefore haul their loads directly from the mines all the way to Richards Bay without having to change locomotives in Ermelo to cater for the change in the power supply. South African Class 21E The Transnet Freight Rail Class 21E of 2014 is a South African electric locomotive. On 16 September 2014, the first of the Class 21E dual voltage electric locomotives for Transnet Freight Rail was rolled out at the CSR Zhuzhou Electric Locomotive Company
