The Timken 1111 was subsequently sold to the NP, where it became NP No. 2626, their sole Class A-1 locomotive. The stability of the wheel arrangement meant that driving wheels up to diameter could be used for high speed passenger and fast freight operation. Lateral control devices allowed these locomotives to traverse relatively sharp curves despite their drivers. The increased boiler size possible with this type, together with the high axle loads permitted on mainlines in North America, resulted in the design of some massive locomotives, some of which weighed as much as 450 tons, including the tender.

After the construction of thirty K class locomotives, the NZR developed the design to strengthen the frame and introduced other improvements, such as roller bearings on all axles and ACFI (''Accessoires pour les Chemins de Fer et l'Industrie'') feedwater heaters. Introduced from 1939, they were also built in NZR workshops, most of them with streamlined shrouding to cover the external pipe work of their feedwater heater systems. The first 35 locomotives were designated K^A class and worked on the North Island mainlines with the older K class locomotives.

. The design work on the engine's condensing apparatus and the enormous condensing tender was carried out by Henschel, who built one locomotive complete with tender as well as sixty of the condensing tenders, to which they held the patent. The other 89 condensing locomotives and thirty tenders were built by NBL. SAR Class 25 3511 (4-8-4) Tender

The Type CZ condensing tenders were slightly longer than their engines. One-third of the total length of the tender was taken up by the water tank and coal bunker, while the rest was taken up by eight large radiators on each side, cooled by five steam-driven roof-mounted fans. Roller bearings were used throughout on all these locomotives, including the coupling and connecting rods, the crosshead gudgeon pins as well as the three-axle bogies of both the standard and condensing tenders. The leading bogies and coupled wheels had Cannon-type axle boxes. The cylinders and frames were cast in one piece, while the steel cylinders and steam chests were fitted with cast iron liners. The tender frames of both locomotive types were also one-piece steel water-bottom castings. Since they were entirely mounted on roller bearings, very little effort was required to move these big locomotives. On the condensing locomotives, spent steam was recycled and condensed back to water for repeated use. Since the steam was not expelled up the chimney, the smokebox contained a steam turbine-driven fan beneath the chimney to keep the draught going. Visual evidence of this altered and slightly longer smokebox is the locomotive's banjo-face smokebox front. The condensing system proved extremely efficient and reduced water consumption by as much as 90% by using the same water up to eight times over, which gave the Class 25 a range of between water refills. In addition, the hot condensate feedwater resulted in significantly reduced coal consumption. SAR Class 25NC 3480 (4-8-4) Tender

However, the Class 25 was a complex locomotive that required high maintenance, especially on the turbine blower fans in the smokebox, whose blades needed to be replaced frequently due to damage by solid particles in the exhaust. The equally complex condensing tender also required frequent maintenance. Between 1973 and 1980, partly motivated by the spread of electric and diesel-electric traction, all but three of the locomotives were converted to free-exhausting and non-condensing locomotives and reclassified to Class 25NC. In the process their condensing tenders were also rebuilt to ordinary coal-and-water tenders by removing the condensing radiators and roof fans and replacing it with a massive round-topped water tank. Since the tenders were built on single cast-steel main frames, it was impractical to attempt to shorten them. Locomotives with these rebuilt Type EW2 tenders were soon nicknamed ''Worshond'' (Sausage dog or Dachshund). 3450 - Pretoria 250481

. The primary objectives of the modifications were to improve the combustion and steaming rate to reduce the emission of wasteful black smoke and to overcome the problem of clinkering. This was achieved by the use of a Gas Producer Combustion System (GPCS), which relies on the gasification of coal on a low temperature firebed so that the gases are then fully burnt above the firebed. The GPCS minimises the amount of air being drawn up through the firebed, the main source of air required for combustion being through ancillary air intakes located on the firebox sides above the firebed.The Ultimate Steam Page
/ref>
/ref>
/ref> The modified locomotive became the only Class 26. Compared to an unmodified Class 25NC, the ''Red Devil'' achieved a 28% measured saving on coal and a 30% measured saving on water, measured during freight service, and a 43% increase in drawbar power based on the maximum recorded drawbar power. Its approximate maximum range in full load freight service on 1% to 1¼% grades was based on its coal capacity, and based on its water capacity. The maximum recorded freight load hauled relative to gradient was on 2% grades, and it could haul a passenger train at a constant speed of on 1% grades. The ''Red Devil’s'' great power, however, also turned out to be its one weakness. The Class 25NC had already proven to be on the slippery side and the much more powerful Class 26, with essentially still the same dimensions as the Class 25NC, was even worse. It was a poor performer at starting or at low speeds on steep gradients.

At certain intervals, the locomotives were taken out from staging, steamed up and put to work to haul trains to test the condition of the locomotives. In the late 1980s, these strategic reserves of locomotives were disbanded and the Class P36 locomotives were distributed to museums and for preservation. Some that had not seen regular use for more than fifteen years and were in the worst mechanical condition, were scrapped. It was found that the roller bearings suffered most by standing unused. When the computerised new class numbers were introduced by the Russian Ministry of Railways, the Class P36 were designated Class 1000.0001 to 1000.0251. In the 1990s, after the collapse of the Soviet Union, a number were sold to private train operators.
