Perhaps Eric or one of you that is more experienced that I can shed some light, or at least agree on what I have just found.
The situation is that doing a loading/unloading loop at Anchorage requires a triple track, very tight curve. Sixty meter radius pieces closely fit the digitized track and that would be the inside track on some curves, outside on others. Another location does not require such a tight curve but it is a best fit for one we do not have and it is double track.
The finding is that the first piece of dynamic, goes in fine, using a +/- 5meter radius value. No problem, vectors show up as expected. Then the 2nd piece goes in (on curves with 60 meter pieces this would be the 3rd piece) and while it snaps on fine, looks right etc. --- EGAD, only the tangent parts generate a vector, none seen over the curve part. I am ass/u/ming that this is a hard error.

I have found that I can fit in two dynamic pieces one on each end of a fixed value curve and while it isn't pretty it works. Apparently the error has something to do with the close presence of another curve?
