O-Scale Coupler Information


We do not make O-Scale "three rail" oversized couplers. Our O-Scale couplers are actual scale size and are designed to be body mounted. Thanks to MTH for making body mounted coupler platforms for Kadee couplers. Most other makes of O-Scale models can be converted to KadeeĀ® couplers with a bit of custom fitting.
