The original frame (lower part of body casting, actually, not the metal Athearn frame) was saved and widened, and a drive was no concern as I planned from the start to build it as a dummy.
The solution on that will be to mount the rear U23B coupler low to match the SD40s and mount the front coupler at the correct height, it will run as the trailing unit. As to mounting the hood on the U23B model I will work out a way that the hood is held on the frame with screws rather than gluing it on as I did with the SD40 models.
While they look pretty good, big picture there are some significant compromises on all three models. One special bummer is that the 3D cabs have some rough surfaces. I was hoping after the bath in Bestine (needed to prep for painting) that they would be smoother, but really they are about the same. I will try to be optimistic that the paint will help level out the rougher side surfaces but realize it will only help so much. I think this may simply be a consequence of the cabs all being scaled up from models developed for smaller scales, although perhaps they were not printed well either.
The next big thing to do is add handrails, I need them on before painting.
As already noted, there are a lot of compromises on these models. Back to the handrails, for example, with all the other things that are a bit off I don’t see a big reason to not just use the original HO handrails. So I will, modifying the end handrails to have the chained off opening in the middle compared to the original Athearn design. It is visually more important that they just match on all three models rather than being exactly correct.
I hope these models come out well but as of this moment I am not real sure of the result, the compromises have me a little worried but hoping still for “good enough.” They should match the modern cars I have from Johann pretty well at least, so that part is good. I will get them done and do my best, I have been pleasantly surprised before. But the next projects after these will be restoration projects, which may be more the direction I head for the thrust of future work. Knowing though that I might get the bug to keep upping my game as a craftsman and do more with 3D parts. Who knows?
In any case, the trio of modern Diesels are getting close and should be finished sometime during the blocks of time for working on models during the holidays. I do look forward to running these, more then!
