The LMS Stanier Class 4P 3-Cylinder 2-6-4T is a class of steam locomotives designed for work over the London, Tilbury and Southend Railway route. 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, albeit simpler, 2-cylinder design.
