and the Karoo. It proved the viability of condensing locomotives in South Africa by attaining a saving of between 88% and 93% on water as well as a lower coal consumption, the latter brought about by the higher temperature of the condensed feedwater. Depending on the operating conditions, a water range of between was achieved. At the end of 1951, the locomotive was relocated to Touws River where it was used for further condensing tests and occasionally put to work in regular service. The positive results of the condensing trials led to the introduction of the Class 25 condensing locomotive fleet in 1953. At that time, no. 2485 was again relocated, this time to De Aar for service on the section via Prieska to Upington on the line to Windhoek in South West Africa. It remained in service there until 1958. Even though its service record and uniqueness justified preservation, it was scrapped in 1961. Illustration The pictures illustrate the Class 20 locomotive as built with a Type MP1 tender, then fitted with a larger capacity Type MT2 tender, and finally after modification to an experimental condensing locomotive with a Type CL tender.
