HO/OO Learning Curve inspired Barrel Car Chain

This product is my interpretation of the famous "Barrel carr" from Learning Curves Thomas & Friends Wooden Railway Toyline.  I grew up with these toys, and thought this would be a great way, in conjunction with my Sodor Lines Cabooses, Sodor Lines Baggage cars, and Learning Curve inspired Barrel Cars, to honor and update those childhood toys.   The Bachmann version of this product features the international Hook and Loop coupling system, with coupling Hooks included.  The Chain version does not feature international Hook and Loop couplings, instead being intended for the more realistic 3-chain and hook coupling system.  All this model needs to be ready to roll is either a set of Hornby 14.1mm or HO scale 38" wheels.
