Thanks Eric. I did see some K-line 21" cars but they are undoubtedly the same generic cars that are used in the Super Chief and others.
I may have a lead on a 2-rail GGD set. I can run 2 rail on my home layout (Atlas 3R track) and I prefer Kadees, but my 2R GGD PRR heavyweights don't track well on our club layout (Gargraves/Ross). Does anyone know what 3R wheelsets will fit the GGD 2-rail passenger cars?
