In 1900, two 2-6-0 saddle-tank locomotives were delivered to the Port Elizabeth Harbour Board from Kitson and Company. In 1904, they were followed by one more from the same manufacturer. The builder’s works numbers of the first two locomotives are not known, but are probably two of Kitson numbers 4079 to 4083 in respect of which no trial date or owner are given in the Kitson Works Trial Book. The third locomotive, Kitson no. 4245, is listed with trial date 8 December1903 and customer H Chaplin P.E.H.B. From the trial date, it would follow that the locomotive could only have entered service in Port Elizabeth early in 1904. The locomotives were similar in appearance and general dimensions to the 1st Class 2-6-0ST of 1876 which had been delivered as a pair of Stephenson's Patent back-to-back side-tank locomotives, before being rebuilt to saddle-tank locomotives by the Cape Government Railways in the 1880s. The new locomotives were slightly larger, with an increased heating surface and tractive effort.
Service
Port Elizabeth Harbour Board
The locomotives were acquired as construction locomotives for use on the Port Elizabeth harbour works. The PEHB used letters to number its locomotives at the time, and the first two of these engines were lettered I and J, while the one which was delivered in 1904 was lettered O.
Cape Government Railways
In terms of Cape Act 38 of 1908, the Cape Government Railways became responsible for the administration of the three major harbours in the Cape of Good Hope with effect from 1 January 1909. The locomotives were therefore all taken onto the CGR roster and renumbered in the range from 1024 to 1026. They spent their entire service lives as dock shunting engines in the Port Elizabeth Harbour.
South African Railways
When the Union of South Africa was established on 31 May 1910, the three Colonial government railways were united under a single administration to control and administer the railways, ports and harbours of the Union. Although the South African Railways and Harbours came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways were only implemented with effect from 1 January 1912. In 1912, the locomotives were considered obsolete by the SAR and renumbered by having the numeral "0" prefixed to their existing engine numbers. Even though obsolete, they remained in service until 1931.
