The last time I looked, Athearn still did the delrin (engineering Plastic) trucks. They had 4 styles, Archbar, Andrews, Bettendorg, and roller bearings. They were being sold built up for about 10 a pair. At various times they have been sold as kits and 10 packs of kits. It is the primary truck I use on kit built cars and any others that give me problems. they are sprung with springs that allow a little equalization which makes them handle rough track better than the rigid trucks we see from a lot of mfgs.
I have had a few Athearn freight car kits and built up over the years. They were very similar to the All Nation line in design and build process. I don't know if they ever did any thing other than reefers and boxcars.
As for the wishlist of locos above, they have all been done, and some very recently and some very well. the GE 44 tonner has been done in brass by Yoder, NJCB, and Sunset, and more than once in some cases. The SW switchers in some forms have been done in brass over the years. And Atlas O still does an SW8/9 in plastic/diecast with a great single motor drive. Babbitt loco works did a 2-6-0 based on the All Nation stuff and of course All Nation/Varney did the 4-6-0 and a few other small locos, including a very nice 2-6-2 using a Cary Cast boiler. Recently Atlas O tried a USRA 0-6-0 which is about as generic as you can get and still have a prototype. It apparently was not a great seller. Most of thse things show up at O scale shows new, slightly used, or Well used. At the recent March Meet, I saw one of the 2-6-2 kits new in box, that priced around 200.
I don't think Athearn can see any products that would be a big entry to the market.
