The '''Cape Government Railways 0-4-0ST 1881 ''Coffee Pot''''' was a South African steam locomotive from the pre-[[Union of South Africa|Union]] era in the [[Cape Colony|Cape of Good Hope]].
In 1881, two [[Cape gauge]] saddle-tank locomotives with a 0-4-0 wheel arrangement were placed in service by Teague and Company, who operated Teague's Tramway at the [[Kimberley, Northern Cape|Kimberley]] diamond mine. In March 1885, one of them was purchased by the Cape Government Railways for use as a construction locomotive, while the other was sold to the Kimberley Diamond Mine. The Railways locomotive was nicknamed the ''Coffee Pot'' while serving as construction engine at [[Norvalspont]].<ref name="Holland 2">{{Holland-Vol 2|pages=110-122}}</ref><ref name="Coffee Pot">[[:Talk:CGR 0-4-0ST 1881 Coffee Pot#Additional information supplied by John Middleton|Email from John Middleton regarding the ''Coffee Pot'']]</ref>
==Cape railways expansion==
In 1876, the [[Cape Government Railways]] (CGR) was reorganised into three semi-autonomous systems, the Western System headquartered in [[Cape Town]], the Midland System headquartered in [[Port Elizabeth]] and the Eastern System headquartered in [[East London, South Africa|East London]].<ref name="SAR History"/>
Construction of the two Midland System mainlines of the CGR commenced in 1874, one line from Swartkops in Port Elizabeth and the other from [[Uitenhage]] towards [[Graaff Reinet]]. The Swartkops line reached [[Alicedale]] in 1877, [[Cookhouse (village)|Cookhouse]] in 1880 and [[Cradock, South Africa|Cradock]] in 1881. At Rosmead, the Midland System linked up with the Eastern System out of East London in 1883, and [[Noupoort]] was reached in that same year. From Noupoort, two lines were constructed. One headed northwestward and linked up with the Western System out of Cape Town at [[De Aar]] on 31 March 1884. The other headed northward via [[Colesberg]] towards the Orange Free State and, also in 1884, reached the [[Orange River]] at [[Norvalspont]]. Here a bridge had to be constructed across the Orange for the line from Colesberg to be continued to [[Springfontein]] in the [[Orange Free State]].<ref name="Holland 2"/><ref name="SAR History">The South African Railways – Historical Survey.

==Teague's Tramway==
In May 1881, Teague and Company began operating on a short {{Track gauge|Cape|allk=on}} line, known as Teague's Tramway, at the Kimberley diamond mine. This isolated line, the first railway in Kimberley, was about one mile long and was used for waste removal, serving many of the companies operating at the mine.<ref name="Coffee Pot"/>
The tramway acquired four locomotives, of which numbers 3 and 4 were {{nowrap|0-4-0}} saddle-tank engines, built in 1881 by [[Ruston, Proctor and Company]] with works numbers 7272 and 7273. They were supplied through agents Sinclaire, Hamilton and Company in 1881, along with 150 four-wheel tip wagons built by Brown, Marshall and Company.<ref name="Holland 2"/><ref name="Coffee Pot"/>
The line was not economic and, when Teague and Company withdrew in October 1881, it was taken over by the Kimberley Mining Board, which itself went bankrupt in March 1883. The tramway ceased to operate after July 1883 and its equipment was offered for sale in March 1885. Of the four tramway locomotives, engine no. 3 was purchased by the CGR and no. 4 by the [[De Beers|Kimberley Diamond Mine]].<ref name="Coffee Pot"/>
==Cape Government Railways==
Engine no. 3 had its [[Railway coupling#Buffers and chain|spring buffers-and-chain couplers]] replaced with the CGR's standard [[Railway coupling#Johnston coupler|Johnston link-and-pin]] couplers. The locomotive was probably never classified or renumbered in CGR service and became generally known as the ''Coffee Pot''. It served as construction locomotive while a temporary rail bridge was being constructed across the Orange River at Norvalspont, later to be replaced by a permanent bridge. In 1889, the ''Coffee Pot'' became the first locomotive to steam across the border between the Cape of Good Hope and the Orange Free State.<ref name="Holland 2"/>
