In the process they were also equipped with Watson cabs with their distinctive slanted fronts, compared to the conventional vertical fronts of their original cabs. In spite of still being nearly lighter after reboilering, they were reclassified to Class 14R along with reboilered Class 14 locomotives instead of to Class 14AR. Even so, they could still be identified as ex Class 14A locomotives by the absence of the big sandboxes on their running boards. Their original Belpaire boilers were fitted with Ramsbottom safety valves, while the Watson Standard boiler was fitted with Pop safety valves. An obvious difference between an original and a Watson Standard reboilered locomotive is usually a rectangular regulator cover just to the rear of the chimney on the reboilered locomotive. In the case of reboilered Class 14A locomotives, two even more obvious differences are the Watson cab and the absence of the Belpaire firebox hump between the cab and boiler on the reboilered locomotives. As intended, the Class 14A was placed in service on the East London mainline. Although they were good engines, they were not very successful there and were soon relocated to be shared between the Cape Western system for use between Cape Town and Beaufort West and the Eastern Transvaal system for use on the line to Delagoa Bay out of Pretoria, particularly between Waterval Boven and Komatipoort. The Cape Western's engines later joined the rest of the Class in the Eastern Transvaal. They proved themselves as free steaming locomotives, low on maintenance costs and trouble-free, and therefore popular with crews and fitters alike. Six were eventually sold into industrial service. The main picture shows second order Class 14R no. 1905 at Klerksdorp, Transvaal, on 17 April 1978. The first of the following pictures illustrate the locomotive as built, while the rest show reboilered Class 14R (ex Class 14A) locomotives in service.
