The Natal Government Railways (NGR) vehicles, named K and S after their manufacturers Kitson and Stephenson, were tank locomotives with a 2'C wheel arrangement. They were adopted as class C by the South African Railways (SAR) . A preserved example of the locomotives built from 1879 is one of the oldest operational steam locomotives in Africa.

description

37 pieces were delivered between 1879 and 1884 and were given the numbers 8-14, 16-26 and 29-47. They were used on the main line leading inland from Durban and replaced the only slightly older Beyer-Peacock machines there .

The locomotives had plate frames, inclined cylinders and an internal Stephenson control . The water supply was in side tanks and the cab was completely open except for the front and the roof. Occasionally, the machines were operated with two-axle tender tenders in order to increase their range over longer distances.

Conversions

Locomotive no. 21 was converted to the 2'C2 'wheel arrangement in 1896, whereby the amount of supplies was also increased. The weight increased from 29.6 to 33.6 t with a slightly reduced axle load. The aim was to achieve equally good running characteristics in both directions, because the locomotive was to be used on the south coast route starting from Durban , where there were no turntables at that time. This locomotive became the model for the slightly larger Neilson-Reid class, built from 1904 onwards . With the SAR it was classified as class C2 with track number 86 and remained in operation until 1931.

Another locomotive, No. 25, was converted in 1901, this time to a 2'C1 'wheel arrangement. At 39.2 t it was even heavier than the 2'C2 '. This machine was designated as class C1 by the SAR and was given the number 77. Another four machines with this wheel arrangement were reproduced in the SAR workshops in 1912, mainly from existing spare parts. They were given the numbers 325–328. They were also in use until 1931.

Whereabouts

The 15 unmodified locomotives that were still taken over by the SAR were given the track numbers 62-76. They were used on branch lines and in shunting services. In 1940 the last copies were taken out of service and scrapped.

One example, the former No. 13 of the NGR and No. 62 of the SAR, named Kitson after their builder , has been preserved. The locomotive had been sold to the Eskom utility company and was in service until the 1980s. In 1983 it was declared a "national monument". Since 1993 it has been on loan to the South African National Railway and Steam Museum (SANRASM) in Krugersdorp and was at that time the oldest operational locomotive in South Africa. However, it is no longer in use.
