When it was noticed that the 75 mph (121 km/h) class 24 was too slow for many tasks, the 90 mph (145 km/h) class 25 was born. Thanks to an intercooler, the engine now produced 90 hp more. Several manufacturers delivered a total of 327 locomotives of subclasses 25/0 to 25/3, which mainly differed in terms of the electrics. They mainly hauled freight trains, but some locomotives had steam heating for passenger trains. They were called “Rats” because of their widespread use. Regular use ended in 1987. In 1983, three locomotives had been converted into electric train heaters, which were carried on trains and scrapped in 1994. Today a total of 20 class 25 units are being preserved.

After the 13 class KK16 freight locomotives, ENR ordered 38 passenger locomotives from Henschel, which in turn were developed based on EMD technology. In contrast to the predecessors, these locomotives only received an engine from the 567 series from EMD, which here had 16 cylinders and delivered 1,950 hp. One motor reduced the length of the locomotive by about two meters. The three-axle bogies were still equipped with two traction motors and a carrying axle. They were designed for a top speed of 120 km/h and were 20 tonnes lighter than the KK16.

After the classes KK16 and AA16, the Egyptian National Railways ordered another 70 diesel locomotives from Henschel, which were again built under license from EMD. They were to be used for light passenger service and were therefore designed with a lower weight. The 567 series engine here had twelve cylinders and delivered 1,425 hp. In this case, four axles were enough, all of which were powered. Since high speeds were not used in lighter service, the maximum speed of 100 km/h was even lower than that of the KK16 freight locomotive. With a total length of almost 19 meters, these locomotives were the shortest of their sister series.
