CSAR Rack 4-6-4RT

what is it?

The Central South African Railways Rack 4-6-4RT of 1905 was a South African steam locomotive from the pre-Union era in Transvaal Colony. In 1905, the Central South African Railways placed two four-cylinder rack tank locomotives with a 4-6-4 Baltic type wheel arrangement in service on the section between Waterval Onder and Waterval Boven. 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.
