The London, Midland and Scottish Railway (LMS) Fowler 2-6-2T was a class of steam locomotive. The LMS classified them 3P, BR 3MT. All were built at Derby Works between 1930 and 1932. William Stanier used them to form the basis for the LMS Stanier 2-6-2T, which was essentially a taper boilered version.
They were initially numbered 15500âÂÂ15569, but from 1934 were renumbered 1âÂÂ70. After nationalisation in 1948 British Railways added 40000 on to their numbers to number them 40001âÂÂ70.
Numbers 15520âÂÂ39 (later 21âÂÂ40 and 40021âÂÂ40) were fitted with condensing apparatus to work around London. Some of the non-condensing ones were fitted with vacuum operated pull and push control.
All were withdrawn between 1959 and 1962. None were preserved.
