==43106 in service==

43106 is the only surviving example of an LMS Ivatt Class 4 [[Whyte notation |2-6-0 Mogul]]. These locomotives were mainly designed for medium freight work but were also widely used on secondary passenger services. They were classified as 4MT by BR. The unusual design with raised running plates led to members of the class being referred to by nicknames such as “Doodlebug” or “Flying Pig”.
