all earlier south african electric locomotives, with the exception of the orex line's class 9es, ran on spoked wheels using spur gears. amongst south african electric locomotives, the class 14e was the first to have solid wheels with double helical or herringbone gears and with a traction motor to wheel gear ratio of 20:103. this gear ratio had the result that, while the three prototypes were very fast, they struggled to pick up a load. the locally built class 14e1, on the other hand, ran on spoked wheels with helical gears and had a more conservative traction motor to wheel gear ratio of 18:67..
