The South African Railways Class 14B 4-8-2 of 1915 is a steam locomotive. In 1915 the South African Railways placed fifteen Class 14B steam locomotives with a 4-8-2 Mountain type wheel arrangement in service. When they were subsequently converted to superheating, they were reclassified to Class 14. Later all but one were reboilered with Watson Standard no. 2 boilers and reclassified to Class 14R. ==Manufacturer== The third version of the Class 14 locomotive was ordered from Beyer, Peacock and Company in 1914. Because it was intended for use on the lower section of the Natal mainline where speeds were low with frequent stops, D.A. Hendrie, then the Chief Mechanical Engineer (CME) of the South African Railways (SAR), concluded that no high degree of superheat would be attainable, so they were ordered without superheaters. These non-superheated versions of the Class 14 became the Class 14B. Like the Class 14, the Class 14B had Walschaerts valve gear and a Belpaire firebox. Fifteen locomotives were delivered from Beyer, Peacock in 1915, numbered in the range from 1746 to 1760.〔〔〔Beyer, Peacock and Company production list, excluding Garratts, Customer List V1 04.08.02〕
