I have added an additional page to my site to link to.
I think there are 10 pages of coastal UK describing small sections and 8 pages of tutorials.
The coastal UK pages are relating to c1800 but were illustrated with the blender 3D content.
Nothing train or Trainz related as my site is about maritime and historical and simulations, c1800.
I used blender 3D to make all content and also the small coastal simulations.
All my content is basic. i.e mainly solid objects but...used in my simulations up to 12 miles square.
Boats, schooners, dock gates, watermills, locks, tides etc, can be made animated etc.
I think that link should find it as it's a new site I made.
To get Blender 3D made content into Trainz you would need to look that up on the Trainz site as I do not use Trainz now and I do not know the details.
There are no simulations to download on my site.
Please refer to Surveyors and Engineers thread as I started a similar thread on that.
