HO/OO RWS Works Unit Coach v1 Chain

This model is based off of the Works Unit Coach that appeared in the Railway Series story Thomas and the Missing Christmas Tree.  This wagon was coupled between Donald and Douglas as they ploughed through the snow to rescue Thomas.  This particular iteration of the product does not feature the international Hook and Loop coupling system, instead being intended for the more realistic 3 Chain and Hook system.  All this product needs to be ready to roll is a set of either Hornby 14.1mm or HO scale 38" wheels.
