A friendly wave from the assistant on the Road Knowledge pairing of Coach No. 40117 (still in the red and grey SAR livery) and E1102 as they make their way back to Danskraal / Ladysmith, after a week of training in Durban. E1102 is a significantly refurbished (2007) Class 5E1 Series 5 electric unit, originally built in 1966. She and her sister, E1101, are now used by Transnet Freight Rail for road knowledge training purposes. For this purpose they are used to push Coach No. 40117, which is equipped with a classroom type setup, full driving controls and large viewing windows at the ends.
