The Cape Government Railways of 1881 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

Between 1881 and 1904, thirteen locomotives entered shunting service at the Table Bay Harbour in Cape Town. They were virtually identical to three Brunel gauge locomotives which entered service as breakwater construction locomotives in Table Bay Harbour between 1881 and 1893. In 1908, they were taken onto the Cape Government Railways roster and in 1912, when the South African Railways was established, eleven were still in stock.[1] [2]

Manufacturers

Thirteen locomotives were acquired by the Table Bay Harbour Board in Cape Town between 1881 and 1904, for use as dock shunters at the harbour. They were delivered in five batches from three manufacturers.[1]

Characteristics

The locomotives were virtually identical to three Brunel gauge 0-4-0ST locomotives which entered service as breakwater construction engines in Table Bay Harbour between 1881 and 1893. Apart from the gauge difference, the Brunel gauge engines had larger bore cylinders of 110NaN0 diameter, compared to the 10inches bore of the Cape gauge engines. Both engine types had domeless boilers with a sandbox mounted in the centre of the saddle tank.[1]

Service

Cape Government Railways

By 1908, no. 1 was already either scrapped or sold. The remaining twelve locomotives were all taken onto the Cape Government Railways (CGR) roster in 1908. They retained their original Harbour Board numbers while in CGR service.[1]

South African Railways

When the Union of South Africa was established on 31 May 1910, the three Colonial government railways (CGR, Natal Government Railways and Central South African Railways) were united under a single administration to control and administer the railways, ports and harbours of the Union. Even though 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 was only implemented with effect from 1 January 1912.[5] [6]

By 1912, eleven of these locomotives survived, but they were considered obsolete and excluded from the South African Railways (SAR) classification and renumbering program. While ten of them were listed in the notes to the renumbering lists as having been excluded, no. 15 was not mentioned. They were initially staged in a shed in Cape Town, but appear to have been placed back in service since a number of them survived into the late 1930s before being scrapped.[1] [6]

Obsolete locomotives on the SAR had the numeral "0" prefixed to their existing numbers, although on these engines it appears that new number plates to that effect were never affixed to them. In the SAR era, no. 09 was transferred to Mossel Bay Harbour and two, numbers 010 and 014, went to Port Elizabeth Harbour. These three engines were eventually scrapped at Uitenhage between 1916 and 1938. No. 15, which was not mentioned in the SAR renumbering lists of 1912, was sold to Lourenco Marques Forwarding Agency in Mozambique in 1913 and employed in the Lourenco Marques docks. The rest remained in service in Table Bay Harbour until they were withdrawn and scrapped between 1913 and 1935.[1]

Works numbers and disposition

The numbers, builders, works numbers, dates ordered, SAR numbers and disposition of these locomotives are listed in the table.[1] [3] [6]
