The LMS Ivatt Class 4 2-6-0 is a class of steam locomotive primarily designed for medium freight work but also widely used on secondary passenger services. The London Midland and Scottish Railway ordered 162 of this type between 1947 and 1952, but only three were built by the LMS before nationalisation in 1948. Designed by George Ivatt, they were classified 4F by the LMS and 4MT by BR. In BR days they were used extensively across the system, being prevalent on the London Midland region and to a lesser extent elsewhere, notably on the Midland and Great Northern Joint Railway, an East Anglian line that had previously been joint owned by the LMS and LNER, where they became the dominant locomotive type. The design was noted for its American looks – the running-plates were positioned at a high level and a gap left ahead of the cylinders. Because of this many locomotive enthusiasts considered it to be the ugliest British locomotive produced, especially those locomotives outshopped with double chimneys (the first 50 engines); however, these gave poor performance and were quickly replaced with single chimneys. The class were withdrawn between 1963 and 1968. Only one example survived into preservation, No 43106, the final member of the class in service, which was based at Lostock Hall depot, near Preston.
