CSAR Rack 4-6-4T
The Central South African Railways Rack 4-6-4T of 1905 is a South African steam locomotive from the pre-Union era in the Transvaal.
In 1905 the Central South African Railways placed two four-cylinder rack tank locomotives with a 4-6-4 Hudson type wheel arrangement in service on the section between Waterval Onder and Waterval Boven, but the locomotives were underpowered and proved to be failures in rack service, with the result that their rack mechanisms were removed in 1906 to convert them to ordinary two-cylinder tank locomotives.
==Manufacturer==
In 1905 the Central South African Railways (CSAR) placed orders with Vulcan Foundry for the construction of two 4-6-4 Hudson type rack tank locomotives for use on the rack section between Waterval Onder and Waterval Boven. According to the designs and specifications of CSAR Chief Locomotive Superintendent P.A. Hyde, the CSAR Rack locomotive was to have a bar frame, two cylinders with bore and stroke, and was to use the same drive system as the ex Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij 0-4-2T Class G rack locomotive which had proven satisfactory.〔
The builders chose not to adhere to the original designs and specifications. The cylinder stroke was reduced to and two inner cylinders of the same dimensions were added to drive the rack mechanism independently. The boiler capacity was not increased to compensate for the additional cylinders and a plate frame was used instead of the specified bar frame. The two locomotives were delivered in 1905, numbered 995 and 996 following on from the number range of the Class G rack locomotives.〔
