    Once the Kadee patents ran out, a number of other manufacturers began to manufacture similar (and compatible) magnetic knuckle couplers. An exact-scale HO model of the AAR coupler has been designed and manufactured by Frank Sergent. [66] This design uses a tiny stainless steel ball to lock the knuckle closed.

    Note: to interpret the number in the left-hand column, these examples illustrate: 3.5 mm scale (HO): 3.5 mm scale measurement = 1 foot (304.8 mm) prototype. The ratio is therefore 1:87.08571, usually reported as 1:87. 1 in scale: 1 in scale measurement = 1 foot prototype, the ratio is reported as 1:12.
