The '''Natal Government Railways Class K 0-4-0ST''' of 1891 was a South African steam locomotive from the pre-[[Union of South Africa|Union]] era in the [[Colony of Natal]].

In 1891, the Natal Government Railways placed five {{whyte|0-4-0|ST}} locomotives in service as shunting engines. One was later sold to the Pretoria-Pietersburg Railway, while two more went to the Harbour Board of Natal. In 1905 or 1906, the remaining two of these locomotives became part of the Natal {{nowrap|Class K}}. By 1912, four of these locomotives survived to come onto the roster of the South African Railways as unclassified obsolete locomotives.<ref name="Holland 2">{{Holland-Vol 2|pages=115, 126-127}}</ref><ref name="Holland 1">{{Holland-Vol 1|pages=119–120}}</ref><ref name="NGR Annual 1906">''The Railway Report for year ending 31 Dec. 1906'', Natal Government Railways.</ref><ref name="SAR&H Sep 1944">Espitalier, T.J.; Day, W.A.J.

==Manufacturer== Five {{whyte|0-4-0|ST}} shunting locomotives were delivered to the [[Natal Government Railways]] (NGR) from [[Neilson and Company]] in 1891, numbered in the range from 89 to 93.<ref name="Holland 2"/>

==Characteristics== The locomotive's cylinders were arranged outside the frame, while the slide valves were arranged between the frames and actuated by [[Stephenson valve gear]] link motion through rocker shafts. The boiler dome was arranged above the firebox, with two [[Safety valve#Salter spring balance valves|Salter safety valves]] which were adjusted to blow off at {{convert|140|psi|kPa|0|abbr=off}}. The locomotive was equipped with a No. 40 combination ejector and two vacuum brake cylinders, each {{convert|15|in|mm|0|abbr=off}} in diameter.<ref name="SAR&H Sep 1944"/>

==Service==

===Harbour Board of Natal=== In c. 1896, two of the locomotives were either sold or leased to the Harbour Board of Natal for use as harbour shunters at Durban Harbour, where they were named ''Andy'' and ''[[Dick King]]''.<ref name="Holland 1"/><ref name="SAR Renumber"/><ref name="Paxton-Bourne"/><ref name="Dulez 150"/>

===Pretoria-Pietersburg Railway=== In c. 1897, another one of the locomotives, no. 90, was sold to the Pretoria-Pietersburg Railway (PPR), where it was named ''Natal'' and employed as a shunting engine. By 1912, when the South African Railways (SAR) classification and renumbering program was executed, this locomotive had also seen service with the ''Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij'' (NZASM) and the Imperial Military Railways (IMR) and was still in service on the [[Central South African Railways]] (CSAR), who used it as a shop engine in the Pretoria railway workshops.<ref name="Holland 2"/><ref name="Holland 1"/><ref name="SAR Renumber">''Classification of S.A.R.

===Natal Government Railways=== [[File:NGR Class K 0-4-0ST on Princess Christian Hospital Train.jpg|thumb|left|On the ''Princess Christian Hospital Train'' at Durban, c. 1900]] The other two locomotives remained in service on the NGR, where they were later renumbered to 510 and 511. By the turn of the 20th Century they were used on light duties like the testing of the vacuum brakes of passenger trains at Durban Station, such as the depicted ''Princess Christian Hospital Train'' which was used to attend wounded soldiers during the [[Second Boer War]].<ref name="NGR Annual 1906"/><ref name="Soul of a Railway 6-1">[https://sites.google.com/site/soulorailway/home/system-6-1/system-6 Soul of A Railway, System 6, Part 1: Durban Old Station.

At some stage in 1905 or 1906, a locomotive classification system was introduced on the NGR and they became part of the Natal Class K, which consisted of a potpourri of different tank locomotive types, including an {{whyte|0-6-0|ST}} and four {{whyte|2-6-0|T}} engines. Both locomotives were still in service in 1905, but by the end of 1906, no. 510 had disappeared from the books.<ref name="NGR Annual 1906"/><ref name="NGR Annual 1908"/><ref name="NGR Annual 1904"/><ref name="Middleton"/>

===South African Railways=== When the [[Union of South Africa]] was established on 31 May 1910, the three Colonial government railways ([[Cape Government Railways]], NGR and CSAR) 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 was only implemented with effect from 1 January 1912.<ref name="SAR Renumber"/><ref name="SAR History">''The South African Railways – Historical Survey''. Editor George Hart, Publisher Bill Hart, Sponsored by Dorbyl Ltd., Published c. 1978, p. 25.</ref>

In 1912, ''Andy'', ''Dick King'', no. 511 and the Pretoria shop locomotive ''Natal'' came onto the roster of the SAR as unclassified obsolete locomotives. The named engines retained their names on the SAR, while no. 511 was renumbered 0511.<ref name="Holland 1"/><ref name="SAR Renumber"/><ref name="Paxton-Bourne"/><ref name="Dulez 150"/>

==Works numbers== The locomotive numbers, works numbers, names and SAR renumber information are listed in the table. The three unspecified names can all be any one of ''Andy'', ''Dick King'' or no. 510.<ref name="Holland 2"/><ref name="Holland 1"/><ref name="SAR Renumber"/><ref name="Paxton-Bourne"/><ref name="Dulez 150"/> {| class="wikitable collapsible collapsed sortable" style="margin:0.5em auto; font-size:100%;" |+'''NGR Class K 0-4-0ST''' |- !
