The Metropolitan Railway A Class and B Class were 4-4-0T condensing steam locomotives built for the Metropolitan Railway by Beyer Peacock, first used in 1864. A total of 40 A Class and 26 of the slightly different B Class were delivered by 1885. Used underground, the locomotives condensed their steam, and coke or smokeless coal was burnt to reduce the smoke. Most locomotives were withdrawn after electrification in the early 20th century, forty having been sold by 1907. By 1936 only one remained, and this is now preserved at the London Transport Museum. Beyer Peacock built a number of 4-4-0T locomotives to the same basic 'Metropolitan' design, for the London & South Western Railway and the Midland Railway, as two examples, with others being sold on by the Metropolitan to other railway companies. As well as working in Britain, examples of the same basic pattern of Beyer Peacock 4-4-0Ts are known to have operated in Spain, on the Tudela–Bilbao Railway, and in Germany, on the Rhenische Railway.
