Jamie,
I actually remember changing the number to 42213, so I'll check that out and fix it if it's wrong. I regret now not changing the track type as I have been doing on my other route. It's now at the stage that it would be more trouble than it's worth to have to redo it all. I think the trees are good content for the age of the version I'm running, (TS2009). I'm sure there's much better quality items available now and as soon as I can I'm going to get TS13. I know that there's always room for improvement no matter what I've done, so it's a case of getting it as good as I can with what I currently have and make improvements when the opportunity arises. The other part of me baulks at the thought of having to totally redo all the effort I've put in so far, but hey, that's what progress is!
Thanks for the feedback though, it all helps to make it as realistic as I can.
Dan.
