These were designated the 14th Class and all of them were initially allocated to Umtali to replace the 13th class Garratts on the line to Vila Machado in Mozambique. From 1939, some of the class were transferred for branchline work in Southern Rhodesia at the Salisbury, Bulawayo and Gwelo depots. In October 1949, the Beira line in Mozambique was taken over by the state-owned "Caminhos de Ferro de Moçambique" (CFM). At the same time, the CFM purchased a number of locomotives from RR, including eight 14th Class Garratts, which continued to work on the Beira line from the new depot at Gondola in Mozambique. In 1950, RR ordered a modernised version of the 14th Class for branchline work in Southern Rhodesia. There were eighteen of them and they were designated the 14A Class. From 1979, they were refurbished for shunting work, receiving roller bearings on the driving and coupled axles and, in many cases, larger water tanks and coal bunkers. By 2012 this class, now on the roster of the National Railways of Zimbabwe, still saw occasional service on Bulawayo shunt duties.
