Durban Harbour “Edward Innes”
The Port of Durban's first shunter was procured by the Port Commission in 1879, but that commission was abolished in 1894. The tasks were later transferred to a seven-member commission, which belonged to the government of Natal. This again ordered a single six-coupled tank locomotive. This was also imported from Leeds, but this time by Hudswell, Clarke and Co.
The six-coupled engine was named after Edward Innes, who was the first Durban port engineer appointed by the old commission from 1881 until his death in 1887. It was a standard tank locomotive
from a commercial builder without any special adjustments for the customer. In contrast to the “John Milne” it had side water tanks and significantly larger supplies, but was about the same in terms of empty weight. When the inventories of the three former colonial railways were recorded in 1912, the “Edward Innes” was still included. However, as it was listed as an internal port shunter, it did not appear in the South African Railways numbering plan. It was used until 1923 and was then immediately scrapped. It outlived the other two locomotives that were ordered after it: in 1902 a four-coupled locomotive with a saddle tank and named “Congella” and in 1904 a six-coupled locomotive from Hunslet named “Sir Albert”.
