With new items of rolling stock and locomotives arriving at Sandstone from Germiston over the next few days, we have been hard at work preparing the display area for the new arrivals. Much of the hard work and ground preparation has been done by our 1965 Caterpillar 621 scraper. 621 tractors were powered by a Caterpillar model D336TA V8 turbocharged and after-cooled diesel rated at 300 horsepower and connected to a Caterpillar eight-speed full powershift transmission, with the first two speed ranges direct converter drive for added torque during loading and pulling out of the cut.

At Sandstone we carry on our tradition of using our older machinery for modern tasks and the Caterpillar 621 is no exception.
