Well I thought I'd give the new Kadee #158 scale whisker couplers a try. I've had some problems with the return springs on the original Kadees losing their ability to return the coupler to center. This mostly occurs on my locomotives where the couplers are forced hard over to one side or the other between MUed locomotives. The new whisker couplers performed really well on my decoupling magnets and were able to couple/uncouple to single cars sitting on a siding. A good report I guess. Time will tell how well the whisker springs hold up. Has any one else tried these new couplers?
