In 3 rail scale basically everything is in scale except the track wheels and
couplers and that is why I'm in 2 rail scale.
OK, so what is the issue you have with the couplers? As a 3RS modeler, I use nothing but Kadee couplers, and I'm now starting to use 2-Rail wheel sets. Do you "2-Raile modelers" use lots of different couplers, rather than the Kadee brand?
