I don't think Athearn or for that matter anybody who has produced N scale has thrown in the towel. It is simply a matter of putting your effort into where the money is particularly now given the economics of the past 8 years or so. HO has always offered more variety than N scale thus continues to be more popular. Try finding a Forney, Class B Climax, or a 2-8-8-4 in N scale as examples. As far as finding what I want in N scale that is basically my fault for the choice of roads I decided to model. If I had decided to model one of the more popular and seemingly mass produced roads like UP, BNSF, or CSX I would have most of what I want in my era. The roads I did decide to model do have a fairly good representation in HO scale they just don't in N scale because the modeler numbers are just not there in this scale. Even the SP&S is fairly well represented in both steam and diesel in HO scale and the SP&S group I belong to have at most five members out of several hundred that are N scale. So I would say that Athearns limited N scale releases and purported re-releases is basically staying where there will be a fairly guaranteed return on the investment.
