For lack of a classification, these locomotives are referred to as 26 Tonners, since the NZASM, who took possession of the PPR, classified its own locomotives according to their weight

In 1896 and 1897, the Pretoria-Pietersburg Railway in the Zuid-Afrikaansche Republiek placed three 26 Tonner0-6-0ST locomotives in service. These locomotives were not classified and, since all three were named, they were referred to by name.[1][2]

The Pretoria-Pietersburg Railway Company (PPR), incorporated in London on 13 May 1896 with a capital of £500,000, constructed a railway which operated northward from Pretoria West via Warmbad and Nylstroom to Pietersburg. The 176-mile long (283-kilometre) line was constructed under a concession granted by the government of the Zuid-Afrikaansche Republiek (ZAR) to Hendrik Jacobus Schoeman on 30 October 1895. Construction commenced in 1897 and the first 80 miles (130 kilometres) to Nylstroom was opened to traffic on 1 July 1898. The remaining 96 miles (154 kilometres) to Pietersburg was completed on 31 May 1899.[1][2]

On 1 May 1899, the southern terminus of the PPR at Pretoria West was connected to Pretoria station of the NZASM by a link line, constructed at the cost of the PPR. Mr. G. Mayo was appointed as the General Manager of the PPR, and the official opening of the whole line took place on 21 May 1899.[2]

The first locomotives of the PPR were three 26 Tonner0-6-0ST engines which were built by Hawthorn, Leslie and Company, one in 1896 and the other two in 1897. They were employed as construction locomotives while the line was being built and were not classified or numbered, but named Pretoria, Pietersburg and Nylstroom.[1][2]
