I have lost track of my copy of the good old TS editor manual and am hoping that someone can let me know where to find it on line.
I have scanned the one for RailWorks if that is relevant to you. It might not be up to date but it covers most things. If you want it I'll PM you a Google Drive link.
If you mean the RW Creator Manual, it's on your hard drive at RailWorks>Manuals>EN>RW Creator Manual_Web.pdf
