British Rails' class 06 was built by Andrew Barclays for the Scotish region to replace the small steam locomotives still in use in the confined industrial areas and dockyards of the Clyde. Hornbys' model has long been one of the most reliable performers and is just at home in a small goods yard as it is in an industrial setting.

The use of small locomotives helps reduce the space needed to build and operate an interesting and satisfying layout, offering more hours of enjoyable shunting, or just watching the local goods train rattling by.
