The Type YE tender first entered service in 1901, as tenders to the first four {{nowrap|6th Class}} {{nowrap|2-6-2}} Prairie type steam locomotives of the Cape Government Railways, which were soon modified to a {{nowrap|2-6-4}} Adriatic wheel arrangement. These locomotives were designated Class 6Z on the South African Railways in 1912.[1][2][3] ManufacturersType YE tenders were built by Neilson, Reid and Company in 1901 and Kitson and Company in 1903.[1] In 1901, the Cape Government Railways (CGR) placed four 6th Class steam locomotives with a {{nowrap|2-6-2}} Prairie type wheel arrangement in service. The engines were soon modified to a {{nowrap|2-6-4}} Adriatic type wheel arrangement. The locomotive and tender were designed at the Salt River works in Cape Town under the supervision of Western System Locomotive Superintendent H.M. Beatty. They would be designated Class 6Z on the South African Railways (SAR) in 1912.[1][2][3] The Type YE first entered service as tenders to these locomotives. More entered service in 1903, as tenders to the CGR Karoo Class of 1903 and the CGR 6th Class 2-6-2.[1][2][3] CharacteristicsThe tender had a coal capacity of {{convert|5|lt|10|lcwt|t|1|abbr=off}}, a water capacity of {{convert|2825|impgal|l|sigfig=3|abbr=off}} and a maximum axle load of {{convert|10|lt|17|lcwt|kg|sigfig=4|abbr=off}}.[2][3] LocomotivesIn the SAR years, tenders were numbered for the engines they were delivered with. In most cases, an oval number plate, bearing the engine number and often also the tender type, would be attached to the rear end of the tender. During the classification and renumbering of locomotives onto the SAR roster in 1912, no separate classification and renumbering list was published for tenders, which should have been renumbered according to the locomotive renumbering list.[3][4] Three locomotive classes were delivered new with Type YE tenders. Bearing in mind that tenders could and did migrate between engines, these tenders should have been numbered in the SAR number ranges as shown.[2][3][4]
Classification lettersSince many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR. The first letter of the tender type indicates the classes of engines to which it could be coupled. The "Y_" tenders could be used with the following locomotive classes:[3]
The second letter indicates the tender's water capacity. The "_E" tenders had a capacity of between {{convert|2800|and|2855|impgal|sigfig=3|abbr=off}}.[3] A number, when added after the letter code, indicates differences between similar tender types, such as function, wheelbase or coal bunker capacity.[3] ModificationThe original slatted upper sides of the Type YE tender's coal bunker were soon replaced by sheet-metal sides.
