They are two different industries. JR's and RRmods are the only "companies" that make content for Trainz. Neither has nearly the man power that companies like Walters, Athearn, or Atlas does. They can pump out new products in a few months and take advantage of economics of scale. They can make the same products because of that. It takes JR and RRmods several months to over a year to make a new piece of content. With them being the only two in Trainz, don't you think it would get pretty redundant if they both kept making the same items, with little differentiation between them? I just look at this from a business perspective because that's what it has turned into (and because business is my major). I'm simply suggesting that both parties look at their strengths, use them, and don't make competitors when they don't need to.
