The CGR 0-4-0ST of 1878 "Aid" is a South African steam locomotive from the pre-Union era in the Cape Colony.
In June 1874, while construction work by the Kowie Harbour Improvement Company was underway at Port Alfred, the Cape Government Railways shipped their 0-4-2 tank locomotive no. 9 "Blackie" from Cape Town to Port Alfred for use as construction locomotive. When it became necessary to regularly ferry the locomotive from one bank of the Kowie river to the other as circumstances demanded, a second locomotive was obtained in 1878, a 0-4-0 saddle-tank engine named "Aid".[1][2]
Port Alfred harbour
In the middle of the 19th century Port Alfred on the Kowie River was considered as a possible third major port in the Eastern Cape, in addition to the ports of Port Elizabeth toward the southwest and East London toward the northeast. The Kowie Harbour Improvement Company commenced work in 1857 to construct embankments and increase the depth of the river mouth. The work was eventually taken over by the Cape Government, who spent more than £800,000 in the attempt to develop the harbour.[2]
When the need arose in 1874 for a construction locomotive on site, the 0-4-2 tank locomotive no. 9 "Blackie", the first locomotive in South Africa, was shipped to Port Alfred by the Cape Government Railways. The engine Blackie, officially named "Frontier", was put to work on the west bank of the Kowie river, but as pressure of work demanded, it became necessary to regularly ferry the locomotive from one bank of the Kowie to the other.[1]
Manufacturer
To do away with the time-consuming tedium of ferrying the locomotive to and fro across the river, an order for a second locomotive was placed in 1877 with Fox, Walker and Company of Bristol in England, through the Crown Agents for the Colonies. Fox, Walker supplied a 0-4-0 saddle-tank locomotive that was shipped in two sections and on two brigs, the Frieda and the Lena, which arrived at Port Alfred on 1 January 1878.[1]
Service
The new locomotive, also built for 4 ft 8 1⁄2 in (1,435 mm) broad gauge, was assembled on the east bank of the Kowie and named "Aid". It worked at Port Alfred until the harbour construction work was terminated around the turn of the twentieth century as a result of continuous silting up of the river mouth, which made the project unviable. The engine Aid was then abandoned and left standing in a shed.[1][2]
Disposal
At some time shortly after the end of World War I, the engine Aid was stripped down and buried on site. Its remains were exhumed in January 1960 and presented to the museum at Port Elizabeth, where it was intended to rebuild the locomotive to a condition suitable for static exhibition, using dimensional drawings of the locomotive that had since been discovered.[1]
However, nothing came of the restoration plans and at some stage the exhumed remains of the locomotive were sold as scrap metal.[3]
