context_page_description: The South African Railways Class 25 4-8-4 of 1953 was a condensing steam locomotive.
  Between 1953 and 1955, the South African Railways placed ninety Class 25 condensing steam locomotives with a 4-8-4 Northern type wheel arrangement in service. The Class 25NC which was placed in service at the same time was a non-condensing version of the Class 25 condenser.
context_section_description: The design work on the locomotive's condensing apparatus and the condensing tender was carried out by Henschel & Son, who built one locomotive complete with tender, no. 3451 with works number 28730. After being trialled in Kassel, it was then dispatched to the North British Locomotive Company (NBL) in Glasgow who built the rest of the Class 25 locomotives, numbered in the range from 3452 to 3540. They were delivered between 1953 and 1955.
  Apart from the complete engine and tender no. 3451, Henschel built sixty more of the condensing tenders to which they held the patent, with works numbers in the range from 28780 to 28839, as well as four spare boilers for the Classes 25 and 25NC with works numbers in the range from 28770 to 28773. The last 29 condensing tenders were built by NBL.
  In 1963, one more condensing tender, no. 3541, was built by the Salt River shops of the SAR on a spare cast frame which had been delivered as part of the original order which called for three spare frames, one for an engine and one each for a condenser and non-condenser tender.
