This 2-10-0 Decapod is a British Railways Standard Class 9F number 92212. Built in 1959 at Swindon Works the engine was designed for BR by Robert Riddles. It is one of the most powerful locomotive types ever constructed in Britain for use on heavy freight trains over long distances. Due to the long wheelbase the center wheelset is flangeless while the preceeding and following wheelsets have flanges of reduced depth.
