The British Railways standard class 2MT 2-6-2T Prairie side tank steam locomotives were designed at Derby Works under the oversight of R. A. Riddles and built at Crewe and Darlington works between 1953 and 1957. 30 were built for local services on the London Midland and Southern Regions and were numbered 84000 to 84029.

The design was derived from the Ivatt-designed LMS Class 2P 2-6-2T, modified to fit a universal loading gauge and utilising standard fittings. The locomotives were coal fired, had two outside cylinders and Walschaerts valve gear.

The class was withdrawn between 1963 and 1966, none were preserved. However, four BR standard class 2MT 2-6-0 locomotives, the tender equivalent, did survive. One of these, No. 78059 is to be rebuilt into a 2-6-2T by the Bluebell Railway because the tender version of the 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.
