LMS 2-Cylindered Stanier 2-6-4T

The Stanier Class 4P 2-cylinder 2-6-4T was a class of 206 steam tank locomotives built between 1935 and 1943 to Sir William Stanier's design for the London, Midland and Scottish Railway. The LMS numbered them 2425 to 2494 and then 2537 to 2672, with British Railways adding 40000, and classified them 4P, which British Railways called 4MT. They were the basis for the Fairburn 2-6-4T. Number 2429 had a starring role as Celia Johnson's branch line engine in the 1945 film Brief Encounter, made at Carnforth station, and 42474 was hauling a train in a collision at Irk Valley Junction, Manchester, in 1953 in which ten people were killed. The first withdrawal was in 1960 and the last in 1967, and none were preserved.
