[[Tank engine]]s with the [[2-6-4T]] wheel arrangement were produced for many different railway systems worldwide and were mainly used for freight and suburban passenger working. They have been less successful on express passenger trains. The earliest known example also originated in South Africa, the [[South African Class D 2-6-4T|Pretoria-Pietersburg Railway's 55 Tonner]] of 1898.<ref name="Holland 1">{{Holland-Vol 1|pages=52-54, 56, 120, 122, 126}}</ref><ref name="Holland 2">{{Holland-Vol 2|page=136}}</ref><ref name="Paxton-Bourne">{{Paxton-Bourne|pages=29, 45, 112, 156}}</ref>
