LMS Compound 4-4-0

The LMS Compound 4-4-0 was a class of steam locomotives designed for passenger work for the London, Midland and Scottish Railway, almost identical to the Midland Railway 1000 Class. The LMS built 195 of them, adding to the 45 Midland engines, and the most obvious difference was a smaller driving wheel diameter, 6 ft 9 in against the Midland locomotive's 7 ft 0 in. They were given the power classification 4P. The LMS continued the Midland numbering from 1045 to 1199 and then started on the lower block of 900 to 939, and after nationalisation in 1948 British Railways added 40000 to the numbers. The class was withdrawn between 1952 and 1961. None survived into preservation, although the first of the Midland 1000 Class engines has been preserved.
