what is it?

The London, Midland and Scottish Railway (LMS) Fowler Class 4F is a class of 0-6-0 steam locomotive designed for medium freight work. They represent the ultimate development of the Midland Railway's six-coupled tender engines. Many trainspotters knew them as "Duck Sixes", a nickname derived from their wheel arrangement.
