The BR Standard Class 2 2-6-0 is a class of steam locomotive, one of the British Railways Standard classes of the 1950s. They were physically the smallest of the Standard classes; 65 were built.
The design was derived from the Ivatt-designed Class 2 2-6-0, with a reduced cab to enable it to fit into a universal loading gauge, and other standard fittings, most notably a taller chimney, others including the lack of an Ivatt dome and side plates connecting the two sections of the engine. Like the LMS predecessor the BR design had a tender cab to enhance crew protection and visibility when running tender-first. They were all attached to a BR3 type tender. These locomotives are often known by the nickname "Mickey Mouse".
