HO/OO Freelance ÖBB Boxcar Bachmann Bogies & Roof

This product is a set of bogies and a roof for my HO/OO Scale ÖBB boxcar line of models.   The Bachmann version of this model features the international Hook and Loop coupling, whereas the Chain version is intended for the more realistic 3 chain and hook system.  This product will need 4 wheelsets of HO scale 33' wheels and a size #4 screw with the associated Hex nut in order to get rolling.  The hex nut will fit in the hex shaped hole on the underside of the chassis and will require glue to stay in place.  The screw will then go through the hole in the bogie and screw into the hex nut attached to the chassis.  Links to the shells and information about Hex screws and nuts will be included below:
