I'm new to the forums, but i played ttd, ttdpath and ottd for 5 years now.
I a mechanical engineer and I`m used to make 3d models of equiment, but i have no knowlegde about textures, light, camera, etc.
I saw that the rails where not taken in the wiki, and I tried to make a model (it took me 20 minutes to make the 3d model, and about 30 to test diferent colors, but didn`t quite get it

I don`t know if there is someone already working on this, but i like to give it a try (as you can see, i do need a little help)..
ps. i used solid edge v9
sorry for the bad english...
