 In most cases, an oval number plate, bearing the engine number and often also the tender type and locomotive class, 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.Three locomotive classes were delivered new with Type XD tenders, built by the same manufacturer.
