Beatty, chief locomotive superintendent of the CGR from 1896 to 1910, they were ordered from the Schenectady Locomotive Works in the United States and partly delivered by Schenectady in 1901, with the remainder delivered from the newly established American Locomotive Company in 1902. Conceived as mixed-traffic locomotives, they had bar frames and narrow fireboxes. In 1912, when these locomotives were assimilated into the South African Railways (SAR), they were designated Class 8X. In 1902, the CGR also placed a single experimental tandem compound Consolidation in service, based on its Schenectady/ALCO-built 8th Class. Delivered by ALCO in 1902, the locomotive was not classified and was simply referred to as the Tandem Compound. In 1912, it was designated Class Experimental 2 on the SAR. In 1903, the CGR received a second experimental tandem compound Consolidation from ALCO. It was similar to the earlier one, but with a larger fire grate and an increased heating surface which enhanced its steaming ability. It also remained unclassified and was also simply referred to as a Tandem Compound. In 1912, it was designated Class Experimental 3 on the SAR. Also in 1903, the CGR received four more Consolidations from Kitson and Company of Hunslet in Leeds. They were very similar to the earlier Schenectady and ALCO-built Consolidations, but with the boiler pitch raised by . Coupled with a shallow firebox, this enabled the grate to be extended out sideways over the fourth set of drivers, resulting in a grate area of compared to the of the previous model. In 1912, they were designated Class 8Y on the SAR. In 1904, the CGR placed its last eight Consolidations in service. These were ordered from the North British Locomotive Company of Glasgow in Scotland and were very similar to the previous four Kitson-built locomotives, but slightly larger in boiler and firegrate area dimensions. In 1912, these eight were designated Class 8Z on the SAR. While subjecting the Consolidations to exhaustive testing on all types of traffic and under varying conditions, some trouble was experienced with the leading pony truck and it was dropped in favour of a four-wheeled bogie in later orders for more eighth class locomotives. All subsequent Cape eighth class locomotives were therefore built with a Mastodon wheel arrangement.
