I'm almost sorry I got my route back. it's a shadow of its former self. Tons of orange boxes for items that are NOT missing, but fail to show. I can "get" them and they can be placed down, but the orange boxes remain.THis means replacement one by one. A lot of the textures are missing (grid patterns showing, but not the texture). If I "get" them, they remain just grid textures and not what they're supposed to be. The primary culprit seemed to be an ordinary 4-way intersection which, once I disabled it, allowed the route to be worked on. The odd thing is once I deleted it from the route, I could place it once more and the route remained stable. There was no error with the content at any time. I may end up kicking this off TS2019 and going back to TANE where I first developed it.
Thanks for all the help.
