This 5” gauge logging loco was displayed by S Lee at Harrogate in 2014. We do not have details of this loco, but it is certainly unusual. Not only does it have a vertical boiler, it is fitted with chain and sprocket drive rather than the usual geared drive. Sprocket drive was used for this type of locomotive by Aveling & Barford before it developed a gear driven version of its traction engines fitted with flanged wheels. Later Shay, Heisler and Climax were to develop the logging engines more familiar to model engineers.
