I also speed-tree'd that route and many others myself.
While the old billboard trees caused performance issues, this doesn't seem to be the problem any longer. The issue now is they don't look good and look like sheets of mylar or cardboard crisscrossed into stars. The billboard trees rendered well for a bit under TANE and early TRS19 then unfortunately N3V "fixed" something and broke that part and now they render poorly.
Track is a different story, although procedural track (pro-track) has gone through a bit of development with a lot of aches and pains to go with it. Pro-track looks well and renders well, today but the early versions are clumsy. It took me until last year to replace all of my older track with pro-track, not that it took that long to do it but more like it took me that long to find something suitable. The problem I found with the early versions is the ties are too narrow and widely spaced and the rails are too thin. This looks okay for transit track, and maybe for some of that found elsewhere, but it doesn't look good for American railroads, meaning both US and Canada. The track is also a bit tricky to work with in some locations where the switches are a bit tighter such as those found on transit lines and in and around industrial areas, but once I've gotten used to its limitations and quirks, I can get things to work well otherwise.
After trying various pro-track "flavors", I've settled on those by Trainsboi and Samplaire with the latter being European with screw fasteners but looks good, in particular the rusty and dirty track, and I'll use that for cruddy old sidings and mostly abandoned or closed lines which are found on my original route I started back in December 2003 and has been under renovation and revisions recently.
