Ex South African Railways Class 6C number 544 is one of a large number of this type of locomotive in various sub classes built in the late 19th century for railway administrations in South Africa.
At the end of the Boer War number 73 was taken into Central South African Railways stock as their number 349.
In 1910 when the Union of South Africa came into being together with a new railway administration, South African Railways, number 349 was classified 6C and renumbered 544 and ended her days as the depot shunter at Bethlehem loco.
