TheDriverDigest, the longest road train in Africa operates at Richardsbay Minerals in KwaZulu-Natal, South Africa.
Operated 24/7 by Unitrans, these road trains are driven on average for 19 hours day by a relay team of four drivers per train.
Each train has a Western Star with a Cummins ISX 565 straight six pulling four Afrit wagons.
Empty the rig weighs 60 tons, which equates to one tone each for the 60 wheels at the back.
With so many wheels, drivers expected the rig to trammel like the devil himself, but a healthy dollop of science and a little voodoo magic from the Afrit toolbox has ensured that each of the axles under the road trains tracks true.

Minerals in South Africa average 19-hour working days.
An Allison gearbox with 14 forward ratios ensure continuous power delivery to the three heavy-duty Sisu axles from Finland.
The elite group of drivers controlling these rigs say the true tracking and continuous power delivery makes driving these 42,15 metre monsters "almost easy", compared to the older, tail-happy three axle road trains.
"Almost", for turning a 42 metre rig tomorrow requires from the driver to have started planning that turn last week. Once committed to a radius, no corrections can be made to the decreasing corners cut by the 30 rear axles.
