I'm trying to export an animated Venetian gondolier I made from Blender. I've had to severely reduce the polygons on it e.g. removing the couple sitting. Now I just have the rower. I then had to cut the boat in half from its original size. My latest error because of vertex count is at 153,984. Can anyone tell me the max vertex count allowed. I wish the exporter allowed a larger number. I wonder if this could not be changed?

Anything above 20,000 polys will be really suspect in Trainz and the CCG guidelines are more like 7,000 polys even for a steam loco.

If you are modeling for 2006 maybe I just did some checking because I wanted to make sure before commenting, but JointedRail's SD 70 just the body mesh is 39,000 and change and it runs rather flawless even when there are many of them in the same scene.
My latest mobile homes are 7500
I've put 150 of these in the scene at the same time and frame rates never hiccuped.
Yeah looking at the CCG I'm committing a mortal sin, but low poly models are just that, low poly models. Now of course my model above started out life very low poly, but as things get added on the poly count went up but actually my personal best exporting from 3DS Max was something like 1,369,000 polys, and it actually loaded in Trainz.
It was a complete rookie mistake, but it did export and load in Trainz the latter only being tried after I realized the former.

Over a million polys! The exporter for 3DS Max is just better than for Blender. After removing the lamp I'm left with 26,915 triangles and 61647 vertices.
I suspect that the SD 70 will have at least some LOD provision, so I doubt if you are typically going to get the top level LOD loaded more than a couple of times if you have a yardful.
And by the look of your system specs, if anyone is going to be able to run a route full of your mobile homes, it's on a machine like that...
Just out of interest, where have the 7500 polys been used? It looks like it should be pretty easy to get down to under 1000 for a distance LOD.

Well 90% is the back steps because they are real (ok virtual) wire mesh..
Now yeah I could do without them or do them using planes but I'm sorry I build what looks good to me for me, and if others want them and can run them they are welcome.
Now yeah my 3 year old i7 may seem impressive but it really isnt and again I am not going to pinch polys and create sad looking stuff hoping someone with a 486 can run it and enjoy it...

Mesh size
I just did a test using the new Y6B steam loco from TS12. In 3D Studio, at LOD0, it has the following values;
149,505 Polys
86,162 Verts
I placed 43 in the same yard in a route I am doing now with said route being 4,259 boards in size at 5 meter squares. Looking straight along the yard tracks, I got the following values in surveyor;
978,088 Vertices
2,309,928 Indices
My system didn't even blink with that load. TS12 has an almost unlimited capacity with certain size reservations for polys and verts.

The current guidelines
http://online.ts2009.com/mediaWiki/index.php5/Modeling_Trains_for_Trainz
say "The sum of the locomotive exterior including all bogies, hoses and fans etc may be up to 120k polygons with four LOD levels provided. It's ideal to aim for a reduction of up to half at each level, though this may not always be possible."
