South African Class 12A 4-8-2 be very successful engines which performed well, with low repair costs. Modifications in design of details after entering service were negligible. None of the SAR Class 12A or Class 12AR locomotives were sold into industrial service, but between 1947 and 1953 eight Class 12A locomotives, similar to the unreboilered SAR locomotives but without superheaters, were built new for industrial service by NBL. The builders, years built, works numbers, reboilering particulars and original tender types are listed in the table.

Because of its length, such a locomotive must be an articulated locomotive. It is not longer than a normal articulated; the fourth and fifth sets of drivers are located under the tender.
