So, I though I was opening a can of worms, but no, it is what it is. Let me explain:
Using T:ANE (did not try on 19 yet). Since you have already a dock with tracks, you do a Bulk asset replacement, so the new track substitutes the one you want to replace. And the magic happens and the selected area get's replaced. But the points, do not show the moving blade nor frogs. A second test was to lay new RTRX track, not by bulk asset replacement. For a moment I thought that by bulk replacement, you lose the procedural track effect, but no, newly laid RTRX not being procedural, would not show the effect. Again not complaining just noting this. Is it possible to change textures and pass the nice cracked concrete to a procedural track? Maybe using John's method, but for now I can live with it. Hope this clarifies what I see here.
