context_page_description: Under the Whyte notation for the classification of steam locomotives, 0-8-0 represents the wheel arrangement of no leading wheels, eight powered and coupled driving wheels on four axles and no trailing wheels. Locomotives of this type are also referred to as eight coupled.
context_section_description: On the South African Railways (SAR), shunting was traditionally performed by downgraded mainline locomotives. When purpose-built 3 ft 6 in (1,067 mm) Cape gauge shunting locomotives were eventually introduced in 1929, the SAR preferred to adhere to the American practice of using tender locomotives for shunting, rather than the European practice of using tank locomotives. Three classes of 0-8-0 shunting steam locomotives were introduced between 1929 and 1952.
  In 1929, fourteen Class S locomotives were placed in service. They were built by Henschel and Son in Germany, designed to SAR specifications. The top sides of the tender’s coal bunker were set inwards and the water tank top was rounded to improve the crew’s rearward vision.
  The second type, the Class S1, was designed by Dr. M.M. Loubser, chief mechanical engineer of the SAR from 1939 to 1949. Twelve of these locomotives, a heavier version of the Class S, were built at the Salt River workshops in Cape Town with the first being delivered in October 1947. A further 25 Class S1 locomotives were ordered from the North British Locomotive Company in Glasgow in 1952 and delivered in 1953 and 1954. The Class S1 was noted for its efficiency and economy and could cope with block loads of up to 2,000 long tons (2,032 tonnes).
  To meet the need for shunting locomotives with a light axle load for harbour work, these were followed in 1952 and 1953 by 100 Class S2 locomotives, built by Friedrich Krupp AG of Essen in Germany. To adhere to the specified weight limit, the Class S2 was built with a small boiler, with the result that it had the appearance of a Cape gauge locomotive with a narrow gauge boiler, particularly when viewed from the front. Also to reduce the axle load, it had Type MY1 torpedo tenders which rode on Buckeye three-axle bogies.
