Rick,
I don't have all the individual files, so I have put this together for you. You will need to download and extract the files you require. I had these for TRS2004 so I am unsure what dependencies are required for each, but the entire site is a treasure trove of narrow gauge logging. Hope you are able to get them all as when I checked this afternoon, they were all available.
All files can be found at
Trainzone.co.nz
