Manufacturer
The first locomotive in the Cape Government Railways (CGR) Consolidation type 8th Class, later to become the South African Railways (SAR) Class 8X, was designed by H.M. Beatty, the CGR's Chief Locomotive Superintendent from 1896 to 1910.
In 1904, a third batch of eight of these locomotives was delivered from the

of Glasgow, Scotland. All eight were allocated to the Western System of the CGR, numbered in the range from 821 to 828.

Characteristics
These locomotives were very similar to the previous four
Kitson-built Consolidations, but slightly larger in boiler and firegrate area dimensions. They also used
saturated steam and cylinders with overhead
slide valves, actuated by inside
Stephenson valve gear. Of the three models of
Type XE1 tender which were in use at the time, these locomotives were equipped with the version which had the coal capacity.

) were united under a single administration to control and administer the railways, ports and harbours of the Union. Even though the South African Railways and Harbours came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways were only implemented with effect from 1 January 1912.

In 1912, these locomotives were designated Class 8Z on the South African Railways (SAR) and renumbered in the range from 900 to 907.
In spite of the difference in wheel arrangement, the CGR grouped its Consolidation and post-7th Class Mastodon locomotives together as the 8th Class. In 1912, all these and locomotives, together with the to Mastodon locomotives from the

Service
In SAR service, the Class 8Z was used mainly in the Western Cape, shedded at Touws River. A few later ended up at Bloemfontein in the Orange Free State and Klerksdorp in Transvaal. They were withdrawn by 1935.
