    By Kaolin2FS,

    One of the reasons I switched to 2FS was the ugliness of the rapido coupling. I'm still not sure there's a perfect solution for its replacement but what I have done, however, is got hold of some 3-link chain from Mathieson Models (usual disclaimer) which is designed to replace the coupler on their wagons. These can be used on many recent Farish wagons with only a modest amount of 'persuading' - simply unclip the coupler pockets, widen slightly if needed, and press the Mathieson coupler lugs into the holes. This is an experiment with HFAs which are about to undergo conversion to CDAs, which in the real world have the 'Instanter' type couplings but in this scale who's going to be able to tell... A comparison:
     
    Farish HFAs with standard coupling at top and 3-link chain replacement at bottom, set on 2FS track:

     
    Difference in length for a rake of 4 (I've kept the rapidos at the end of the bottom rake to facilitate coupling for the time being, they will be replaced with DGs idc):

     
    Traversing N-gauge Peco medium-radius turnouts (inset into 'concrete' - more on this another time). No buffer-locking evident:

     
    Given the success of this experiment using the greater N-gauge tolerances, I'm not expecting any problems in 2mm, but I'll let you know...
