Tracks, pass 2

Here is the latest look at my tracks. There IS a texture on the tracks, but its been blown out by a read-only environmental sun and sky node in the scene file. The material on the posts is mental ray only, so I had to render using this. The quality is poor because I had to render it on my home computer, but you can at least get a sense of how the layout looks and how I have changed the design of the posts.
