Hunt Couplings

A PRACTICAL alternative for the common but obsolete tension lock coupling remains to be agreed and engineered by the mainstream manufacturers for ‘OO’ gauge models.

The adoption of NEM-362 coupling pockets with their well defined specification seemed to be difficult enough, with Bachmann mounting them at the wrong height at the start and other manufacturers occasionally failing to apply the standard correctly for the height of the coupling box together with its position in relation to headstocks. Supplying a stepped shank tension lock coupling resolved the problem for coupling to other tension lock fitted models, but failed to address the needs of alternative NEM-362 compatible coupling systems – the whole point of the exercise in establishing such a standard. Based on experience, modellers would be excused in thinking that a new, more realistic working coupling system that
