LMS Stanier Class 4P 3-Cylinder 2-6-4T is a class of steam locomotive designed for work over the London, Tilbury and Southend Railway. All 37 were built in 1934 at Derby Works and were numbered 2500–2536. The third cylinder was provided to allow increased acceleration between the many stops on the L.T.&S.R. line. From 1935 the LMS switched to constructing a very similar, simpler, 2-cylinder design. In 1941 two of the class had just been released from overhaul from Derby Works at the same time as a Jubilee class 4-6-0 failed in Derby station. The two tanks took over and got the train into St Pancras only 25 minutes late.

The class were withdrawn from 1960 to 1962.
