The British Railways standard class 2MT 2-6-0 Mogul tender steam locomotives were designed by R. A. Riddles and built at Darlington works between 1952 and 1956. They had a light axle loading of just under 14 tons to operate on lightly laid routes and secondary lines. 65 were built, numbered 78000 to 78064.
The design was derived from the Ivatt-designed LMS Class 2F 2-6-0, modified to fit a universal loading gauge and utilising standard fittings. The locomotives were coal fired, had two outside cylinders, Walschaerts valve gear and were fitted with BR3 tenders.
The class was withdrawn between 1963 and 1967, four survived the cutters torch. Nos. 78018, 78019 & 78022 are preserved as built but 78059 is to be rebuilt into a BR standard class 2MT 2-6-2T by the Bluebell Railway. The Mogul class was never allocated to the Southern Region whereas the tank version was, and is therefore more appropriate for the Bluebell’s Southern Region location. It will be numbered 84030, the next number in the original series. 78059 was chosen primarily because it lost its tender while at Woodham Brothers scrapyard, Barry.
