The London, Midland and Scottish Railway (LMS) Ivatt Class 2 2-6-0 is a class of steam locomotive designed for light mixed traffic. Elderly 0-6-0s formed the backbone of the low-powered locomotives within the LMS fleet. William Stanier had concentrated on introducing larger engines and it was left to George Ivatt to introduce a new class of low-powered locomotive. He designed a tender version of the Ivatt Class 2 2-6-2T

Further engines of this type were built as the BR Standard Class 2 2-6-0, these locomotives having BR standard fittings and a modified cab and tender profile to allow completely unrestricted route availability; both LMS and BR 2MT moguls are often nicknamed "Mickey Mouse".

A total of 128 were built between 1946 and 1953, mostly at Crewe. 20 were built by LMS and 108 by BR. Seven members of the class have been preserved and six have run so far.
