Athearn, models representing a balance of detail features and price point, in HO and N scale. Roundhouse, representing affordable, durable models for entry-level buyers; from 2004 to 2015 the line consisted of former "Blue box" models only. [6] McHenry, HO-scale and N-scale model railroad couplers
In the larger scales, working scale or near-scale models of Janney couplers were quite common, but proved impractical in HO and smaller scales. For many years, the "X2F" or "Horn-Hook" coupler was quite common in HO scale , as it could be produced as a single piece of moulded plastic.
