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.

Numbering

They were initially numbered 15500–15569, but from 1934 were renumbered 1–70. After nationalisation in 1948 British Railways added 40000 on to their numbers to number them 40001–70.

Numbers			Lot Number	Date built
Original	LMS 1934	BR	Lot Number	Date built
15500–20	1–21	40001–21	21	1930
15521–49	22–50	40022–50	29	1931
15550–69	51–70	40051–70	20	1932

Variations

Numbers 15520–39 (later 21–40 and 40021–40) were fitted with condensing apparatus to work around London. Some of the non-condensing ones were fitted with vacuum operated pull and push control.

Withdrawal

All were withdrawn between 1959 and 1962. None were preserved.
