Last Christmas, I built a small layout on a closet door for my 9-year old grandson. I used Kato unitrack and mostly Bachmann locos and rolling stock. He seems to enjoy it, and doesn't seem to have much difficulty with the size. I do, but mostly because I model in HO. I am sure glad I did not convert to N-scale several years ago when I was condisering.
We started out with freight cars with Rapido couplers, and soon found there is much discrepancy in the coupler mounting height of these truck mounted couplers, and they uncouple frequently.
Now I am in the throws of converting all of the Rapidos to Bachmann's dummy knuckle couplers. Microtrains are too expensive and too "fiddly" for my grandson or myself.
I need to replace the couplers on his two Diesel locomotives: both Bachmann - a Spectrum F7A and a non-Spectrum U30B. The front of the F7 and both ends of the GE have what look like extended shank couplers. I Bachmann couplers I bought are not long enough.
I went to Bachmann's web site and found their N-scale parts list is very limited. They don't list the replacement knuckle couplers at all.
I need to find a source for the extended shank couplers for the locos. Anyone know where I might go? A Google search turned up only the short-shank couplers in multi-packs.
