The CSAR class 10-2 is made up of Pacific tender locomotives which were primarily based on the Class 10. In 1910, five locomotives were built without and five with a Schmidt superheater. Here it was shown that the locomotives with a superheater could pull about 25 percent more. In 1911 five more were built with superheaters and in 1912 the SAR classified the two variants as class 10A and 10B. In the thirties a total of ten were fitted with the standard boiler No. 1 of A.G. Watson and renamed class 10BR. They remained in service until 1974.
